The System of National Accounts or SNA (until 1993 known as the United Nations System of National Accounts or UNSNA [1] ) is an international standard system of concepts and methods for creating national accounts. [2] The system is nowadays used by almost all countries in the world. SNA-type national accounts are among the world's most important sources of macroeconomic statistics. They provide essential data for empirical macroeconomic models and economic forecasting. [3]
When governments use SNA standards to guide the construction of their national accounting systems, it results in much better data quality and data comparability (between countries and across time). In turn, that helps to form more accurate judgements about economic situations, and to put economic issues in correct proportion — nationally and internationally.
The first international standard was published in 1953. [4] Additions and revisions were published in 1960, 1964, 1968, 1993 and 2008. [5] After more than four years of work and global consultation with a thousand experts, the pre-edit version for the SNA 2025 revision was adopted by the United Nations Statistical Commission at its 56th Session in March 2025. [6] Behind the accounts system, there is also a system of people: the people who are cooperating around the world to produce the statistics, for use by government and international agencies, businesspeople, media, academics, political parties and interest groups from all nations. [7]
SNA guidelines have now been adopted in more than 200 separate countries, territories and areas, [8] although in many cases with some adaptations for local circumstances. [9] Whenever people in the world are using macroeconomic data, of their own nation or foreign nations, they are most often using information sourced (partly or completely) from SNA-type accounts, or from social accounts "strongly influenced" by SNA concepts, designs, data and classifications. Economists and officials across the world depend on timely SNA data, to monitor economic activity, evaluate policy options, and make strategic decisions.
Adherence to SNA standards by national statistics offices (abbreviated "NSO's" [10] ) and by governments has always been strongly encouraged by the United Nations and its partner organizations. However, using SNA guidelines for compiling national accounts is in principle voluntary and not mandatory. [11] What countries are able to do, will depend on available capacity, local priorities, and the existing state of statistical development. [12] Government agencies usually determine their own policies for economic statistics, within the framework of local laws. However, cooperation with SNA has many advantages in terms of data comparability and data quality, gaining access to data, exchange of data, data dissemination, cost-saving, technical support, and scientific advice for data production. [13] Most countries see the advantages, and are willing to participate. Moreover, if reliable and up-to-date SNA macroeconomic data is not available, this could hinder the financial strategies of governments. [14]
The SNA-based European System of Accounts (ESA) [15] is an exceptional case, because using ESA standards is compulsory for all member states of the European Union. [16] This legal requirement for uniform accounting standards exists primarily because of mutual financial claims and obligations by member governments and EU organizations. [17] Another exception is North Korea (the DPRK). [18] North Korea is a member of the United Nations since 1991, [19] but does not use SNA as a framework for its economic data production. Although North Korea's Central Bureau of Statistics does traditionally produce economic statistics, [20] using a modified version of the Material Product System, its macroeconomic data area are nowadays not (or very rarely [21] ) published for general release. [22] UNDP and the Bank of Korea produce a few estimates; the validity of the Bank of Korea estimates has been disputed. [23]
The global grid of the SNA social accounting system continues to develop and expand, and is coordinated by five international organizations: United Nations Statistics Division, [24] the International Monetary Fund, [25] the World Bank, [26] the Organisation for Economic Co-operation and Development, [27] and Eurostat. [28] The European Commission [29] is also involved, via membership of the Intersecretariat Working Group on National Accounts (ISWGNA) [30] set up by the United Nations Statistical Commission (UNSC) [31] to promote cooperation between statistical agencies worldwide.
There are also other UN organizations which contribute to SNA development, in specific areas. For example, UN regional commissions can assist with SNA capacity building, technical/scientific advice and accounts design (discussed below). The United Nations Conference on Trade and Development (UNCTAD) and The United Nations Office on Drugs and Crime (UNODC) created a conceptual framework for measuring illicit financial flows (IFF's) which is consistent with SNA concepts. [32] The UNECE Statistical Division is pioneering the use of artificial intelligence in UN statistical operations. [33] The United Nations inter-agency forum called Committee for the Coordination of Statistical Activities (CCSA) [34] brings together international and supranational organisations whose mandate includes the provision of statistics. The CCSA promotes inter-agency coordination and cooperation on statistical programmes, and consistency in statistical practices and development across the world.
All these organizations (and other associated or related organizations) have a vital interest in internationally comparable economic and financial data, based on data sets obtained regularly from NSO's, and they play an active role in the publication of international statistics for data users worldwide. The SNA accounts are also "building blocks" for many more macroeconomic data sets which are created using SNA data in combination with other data.
The precise historical origins of accounting are disputed by scholars, but the practice of accounting already occurred millenia ago in the ancient Near East; in Europe, double-entry business accounting was practiced in Northern Italy circa 1300 AD. [35] Similar sorts of accounting techniques were also developed independently in China, India, Iran and Arab countries. [36]
The first systematic attempts at national accounting by individual researchers in Europe, from the 17th century through most of the 19th century, aimed mainly to estimate national income and national wealth. [37] The first known attempt in England was by William Petty, in 1665. Petty tried to work out how best to spread the tax burden caused by government spending on the second Anglo-Dutch War (1665–1667). For this purpose, he estimated the income and capital of England. [38] The new science was often called “political arithmetick” (a term invented by Petty) – it aimed to calculate what the best policies would be for the state and the country, with recognition of different economic, social and political interests at stake. The first known estimate of “value-added” in England was created by Arthur Young around 1770, in a production account for agriculture; he also created a national income estimate for England. [39]
At first individual researchers in different countries followed their own approach, although they borrowed ideas from each other. In the 1830s-1850s, "statistical offices" and national "statistical societies" were founded in Europe and America, and in the mid-19th century, the idea arose of "organized contacts between the statisticians of different countries although informal contacts occurred earlier". [40] In those days, the name "statistics" referred mainly to "matters of state", and British statisticians were often called "statists". [41]
Adolphe Quetelet was the driving force behind an international statistical congress held at Brussels in September 1853, and more congresses followed. The International Statistical Institute was founded in 1885. Subsequently (and especially in the 1930s) interventionist governments began to organize much more statistical research, and used national income & wealth estimates regularly to inform their fiscal, social and economic policies. [42] The production of “official statistics” was often delegated as a specialized service to separate statistical authorities, bureaus or institutes which had considerable scientific autonomy, partly to safeguard the objectivity and scientific integrity of data reports.
The first official estimates of national income were made in Australia (1886), Canada (1925), Soviet Russia (1925), Germany (1929), Netherlands (1931), New Zealand (1931), United States (1934), Turkey (1935), Yugoslavia (1937) and Switzerland (1939). [43] In Britain, the Central Statistics Office established in 1941 created the first official white papers with annual estimates of national income and expenditure, which subsequently became a standard feature of the Blue Book. [44] In the United States, a standard national accounting system was in development after a report to the US Senate in 1934, based on initial studies of US national income. From the 1930s onward and especially during the reconstruction era after World War 2, more and more countries began to publish annual official estimates of gross national product and national income.
A recommendation for a global standard system for national accounts was first tabled at the League of Nations in 1928. At its eighth session held in April 1939, the League of Nations Committee of Statistical Experts officially decided to create global standards for national accounts. Standards for banking accounts and balance of payments accounts were also to be created. However, the activities of the Committee were interrupted by World War 2 (1939–1945), and the work resumed at its Princeton conference only in December 1945. The approach that the United Nations subsequently took was “no radical innovation, but a logical development of recent investigations in the field of national income”. [45]
The first global national accounts standard, SNA 1953, was an initiative of the United Nations Statistical Commission. The United Nations believed that the creation of internationally comparable economic data was essential for its own work, and that such data would also serve many other policymaking needs of government and intergovernmental agencies. UNSD provides a useful overview and summary of the historical evolution of SNA across the last eight decades, with supporting documentation. [46]
Nowadays, the role of the state in the economy has become much larger (see Wagner's Law). [47] As a corollary, the standard national accounts have become much more sophisticated and comprehensive. The first SNA manual in 1953 was 46 pages long, but SNA 2025 has more than a thousand pages (not including supporting handbooks and other methodological documents).
All of this means that detailed data is nowadays produced for “which types of economic actors do what, with whom, in exchange for what, by what means and rights, for what economic purpose, and how this changes the financial position of the national economy (or parts of it)”. [49] To create comparable data for all countries, requires a conceptually rigorous, logically consistent accounting system, and standardized measurement practices. SNA provides that unitary framework, for the whole world.
The Penn World Tables and the Maddison Project provide long-run historical time series for SNA-based gross product, national income and capital formation statistics, covering most countries in the world. This data is used by economists, econometrists and economic historians for statistical comparisons and trend analysis across long intervals of time. [50]
The flagship academic journal for research on national accounts is the online Review of Income and Wealth, published since 1951 by the International Association for Research in Income and Wealth. Other journals include, for example, the Journal of Income and Wealth, the National Accounting Review, Journal of Economic Perspectives, Survey of Current Business ,and the Review of Economics and Statistics.
Series of technical papers and documentation covering national accounts topics include the United Nations Statistics Division publications, the OECD Working Papers, OECD Reports and research papers,IMF Staff Papers, IMF Working Papers, World Bank documents and reports and Eurostat statistical working papers. Each of these organizations has its own library or publications portal, which can be accessed online. [51] Often NSO's publish their own methodology papers, and may send a copy to UNSD, which archives it in databases linked to UNdata. [52]
To master the whole of the national accounts system in detail takes a long time and a lot of effort. Even very experienced statisticians may not know some details, or can still find some parts of it difficult to understand. Broadly, the SNA framework consists of a series of standards which guide the production of national accounts, including:
The framework standards guide SNA data producers about what to do, how to do it and why it should be done in a specific way. There is often room for some flexibility of interpretation, but if the standard is accepted, then data have to be produced in line with the standard. It is not possible to set out the whole SNA framework here; this article gives only some of the main points. The official SNA manuals (and associated technical handbooks with detailed guidelines) provide in-depth and detailed coverage. [54]
To compile an entry in an SNA account, basic logical steps are: accounting goal → economic concept → accounting rules → appropriate measure → measurement technique → data collection → data collation, registration and storage → data calculation/estimation → data result (a statistic) → data vetting/testing → data approval → inclusion in the new accounts table(s) → data publication. In reality, however, the sequence of the data production process may not be so linear and straightforward. For example,
In practice, the SNA framework used by NSO national accounts statisticians has the following main components: [56]
All these aspects have to be identified, decided on, approved and documented by the national accounts team and the NSO management, as the official methodology. The NSO has to be able to "account for the accounts", i.e. what was done, how it was done, why it was done, where it was done, and who did it. In principle, it must be possible to track down the whole data production process for every part of the accounts, from beginning to end. One of the reasons is, that if there is a data change, gap or error, it must be clarified what exactly the effect or implication is of that issue for other, related data.
The SNA concepts form a logically consistent system. SNA categorization is conceptually coherent, mathematically rigorous and testable. However, in practice SNA is not exactly 100% consistent, for several reasons:
In a double-entry accounting system, for every recorded expenditure/payment there exists in principle always a recorded revenue/income or receipt (and vice versa), for every recorded debit there is a recorded credit (and vice versa), and for every record of a withdrawal there exists a record for an deposit. This enables checks and controls for the accuracy and reliability of the estimates. In the case of Balance of Payments data, the international transactions are usually measured both by the sending country and the receiving country, enabling reliability checks of the data sets. In principle, each line-item in the core accounts, whether a large or small aggregate, can be derived by adding/subtracting other items in the accounts and/or via standard equations, and the tallies can be verified exactly.
If a change is introduced in one part of the system, it can have consequences for other parts of the system, and lead to revisions of the estimates. For example, in December 2024 the National Bureau of Statistics of China (NBS) stated that it had revised the 2023 estimate for the value of GDP by +2.7%, after taking into account the results of the 5th national economic census and a change in the method for calculating housing services of urban residents (the impact on the reported economic growth rate for China in 2024 was rather small). [59] In Europe, the ESA 2010 implementation and the introduction of other statistical improvements had the effect of raising the level of EU-28 gross domestic product (GDP) by 3.7% in 2010. [60]
National accounts are integrated, composite statistical systems. They bring together raw data, calculated data, estimated data and ready-made statistics using a great variety of sources. Typically, hundreds of separate data sources are used for a complete set of annual national accounts, depending on the size and complexity of the country's economy. The source of the data could be a survey, a publication, a government agency, a business agency or institution, an econometric model, or an unofficial source etc. Some of the data sets are fully produced by the national statistics agency itself, some data is imported readymade from other agencies, and some data is obtained from elsewhere but reworked for use in SNA accounts.
National accountants often act as "statistical engineers", who reconcile thousands of inconsistencies between different sources, to obtain valid estimates which conform to national accounting standards. [61] An economic "map" is created for all measured transactions in the national economy. In this map, all stocks and flows are allocated and categorized according to SNA rules. For every entry in the SNA accounts, the appropriate measurement methodology is defined by statisticians, consistent with the SNA manual and SNA handbooks. [62]
In principle, there is a place in SNA for almost every type of transaction in the economy. However, some things that happen in the economy are not measured in SNA accounts. [63] That is either because they are conceptually excluded from the SNA framework, or because it is practically difficult to estimate them accurately (for example, specific changes occurring within an accounting interval, or changes completed across several accounting intervals; the sales and purchases of specific types of used goods; illegal and informal transactions).
SNA statisticians get the data and information they need to compile the national accounts from ten types of possible data sources:
SNA statisticians can refer to all kinds of national and international documentation, including scientific or other academic literature and news stories. But they cannot collect data from just any source at will. [65] Much of the detailed source data used to produce economic statistics is confidential, classified or secret information (for privacy, military, official and business reasons). In the private sector, there are trade secrets and in the public sector there is classified information. Access and use rights for this information require special authorization. Normally only the anonymized aggregates derived from the detailed base data are accessible and published in the accounts (many more tables and accounts are produced by national accounts research staff which are not accessible to the general public, or which are not officially published).
Normally there exists a national or federative legal framework [66] for the collection and publication of all official statistical data (not just SNA data), which defines (1) the obligations to supply and collect data, (2) legitimate use of data, (3) protection of data, (4) privacy rights and (5) rules for the release of data. The NSO must specify "under whose authority" the information is collected, and "for what purpose". National accounts data can only be collected if it is really necessary to produce the national accounts. In this way, the response burden is kept within acceptable bounds for data suppliers, unnecessary costs are avoided, and there is less chance of response error, data sabotage or non-compliance with information requests (see, for example, the 1980 Paperwork Reduction Act of the United States).
An important reason why some types of information are traditionally not collected, is simply because there is resistance to supplying it and a lack of trust. Sometimes the data is practically difficult to obtain. Ultimately SNA statistical research cannot be done successfully, if people do not or cannot cooperate with information requests. Different countries have different laws, but usually there are norms and rules for relevant data collection. A lot of thought goes into finding the best ways to approach individuals and organizations with information requests, so that the response rate is high, the response burden is low, response errors and response bias are low, and response quality is high.
The observables about the national economy which are the basis for SNA accounts concern the recorded activities of buying and selling; owning, paying and renting; lending and borrowing; disbursing, receiving, depositing and saving; leasing and hiring; financial gains and losses; insuring, charging, taxing and levying; and various other types of financial claims and counter-claims. These economic observables can be identified, allocated and grouped for accounting purposes using six sorting criteria:
Using information about these six criteria, plus SNA accounting rules, and a lot of economic/legal/administrative knowledge, statisticians categorize, group, adjust, aggregate and reaggregate all the observables into a large set of stock values and flow values. [67] These stocks and flows are the basic units of all the accounts in the SNA system. Each line item in the SNA core accounts is either a stock value, or a flow value. Each item can increase in value, stay constant or decrease across time, so that the trend can be measured. There are three noteworthy exceptions:
Part of the work involved in allocating observables to categories can be automated with the aid of computer programmes, but part of the work requires the human judgement of SNA statisticians. Some transactions are easily identifiable and countable, because they always occur in the same way, and for the same purpose. The way these transactions are recorded is plain, straightforward and uncontroversial. But there are other transactions which are much more complex and changeable — they may not be consistently recorded, and therefore they are more challenging to categorize and allocate correctly for accounting purposes. To understand some types of business and government processes requires a lot of knowledge. To understand the data aggregation methods also requires a lot of specialist knowledge.
To compile the whole inventory of SNA stock values and flow values, a complex grid of concepts, definitions and rules is applied. [68] In this way, all the base data collected to build the accounts is ordered and structured. An annex document of the SNA 2008 manual provides an overview of the structure of SNA classifications, each of which has its own codes (SNA 2025 will introduce some revisions). [69]
The logical starting point of the ordering task consists of grouping the types of registered/recorded “institutional units” of a country, guided by the Classification of Institutional Sectors. An institutional unit is a separate economic entity which can engage in production and/or trade with other entities in its own right, receive income, own assets and incur liabilities (debts or other obligations to pay). Normally an institutional unit maintains its own business accounts. Institutional units are usually legally defined organizations, social groups, or households consisting of one or more economically active persons. The main types of institutional units are:
• Financial corporations.
• Non-financial corporations.
• Non-incorporated enterprises.
• Government organizations.
• Households.
• Non-profit organizations.
• Foreign institutional units [70]
Institutional units can be grouped in sectors, and institutional sectors also contain sub-sectors, which identify and distinguish e.g. public and private, market and non-market enterprises, and domestically owned and foreign-owned enterprises, as well as different types of households. Usually the characteristics of all units are registered in large databases with metadata (including physical and postal addresses), and are continuously or regularly updated. These databases are the largest, most detailed collection of information about all the organizations active in the national economy.
All economic activities of institutional units in a country are identified and grouped with the aid of the 2023 International Standard Industrial Classification of All Economic Activities (ISIC version 5) or one of its predecessors. [71] When all economic activities are registered in databases with metadata, according to their characteristics, it is possible to sort the data in a huge variety of different ways, at higher or lower levels of generality/specificity. This makes detailed and comprehensive comparisons possible for different economic activities, both within countries and between countries.
There are dozens of other classification systems which are applied to categorize stocks and flows in SNA accounts and sub-accounts. Some classifications are universal, others are tailored to local conditions which could be relatively unique. At more detailed levels, the classification systems may be guided by existing SNA standards, but they may also be adapted to local circumstances or specific purposes (depending on the economic structures and processes involved). For example, the IMF Balance of Payments statistics modify and expand the SNA standards for external transactions with extra details.
The standard classification systems are designed to enable international comparisons. But they are also designed to provide data that give insight into local economic conditions. Statisticians normally try to design categories which combine standardization requirements plus technical essentials with the known needs of data users. If the data categories are not suited to the analyses that researchers want or need to do, or if they are not consistent with what the government requires, then the statistical information is not useful. So this matter has to be thought through carefully and comprehensively.
Categories and classifications in SNA are not so easily changed, because that can create new problems of statistical comparability, and because it can change the estimates of related statistical aggregates. Any classification change must be consistent with SNA concepts. Usually the majority of changes occur when a new SNA revision is released. Examples of some other global standard classifications that are, or will be applied in SNA are:
Traditionally, the SNA framework provides a set of ten core accounts. The detailed design and terminology has changed somewhat through successive revisions, but conceptually the design remains more or less the same. The accounting principles for each of these core accounts are explained in the SNA manual. Broadly speaking, the ten traditional accounts deal with four main topics: (1) national income, expenditure & product, (2) national capital formation and investment, (3) the national financial position, and (4) foreign transactions of the nation. This provides economic insight into what is happening with production, the generation, distribution and use of income, and the accumulation of wealth of the nation. The ten core accounts can be described as follows:
The majority of member countries of the United Nations compile these ten "core" accounts. For each of these core accounts, more detailed breakdowns are possible in additional tables. However, NSO's usually do not publish a complete national set of all “possible” SNA accounts. They might not even supply a 100% complete set of national SNA data for the core accounts they do publish. The reasons could be (1) that some sorts of data are not applicable, (2) it is currently too difficult or costly to produce the data, (3) relevant data is not (yet) available, (4) the data is already published elsewhere, (5) there is some kind of official or legal restriction on data production. For example, if there is a lot of tourism in a country, a standard tourism account makes sense. But if there is very little tourism, then producing a standard tourism account may lack a good justification. NSO's may also produce and publish extra tables and accounts external to the SNA system, in addition to required core accounts.
The SNA 2025 framework changes the formats of the core accounts to some extent. An important new step in SNA 2025 is the acceptance of more comprehensive household accounts, which according to many experts ought to be a standard feature of national accounts (household income, expenditure, assets, liabilities/debts and net wealth). The experience of the 2008 financial crisis revealed that changes in the financial position of households can have very large macroeconomic effects. Traditionally, statistics offices have collected data on household income and spending, but not for the whole financial position of households. An important reason could be that many respondents find the financial survey questions too intrusive, and do not want to cooperate (but respondents might also have difficulty to supply the information). However, in the digital era (and because of legal changes), people's attitudes have often changed, so that they are more willing to provide information (with proper data custody, and anonymized by the statisticians), because they recognize its national importance.
Each of the SNA core accounts can be complemented with annexes providing extra details, sub-accounts with more detailed breakdowns, satellite accounts linked to the core accounts, and supplementary tables (or account variants) providing additional information. Some of these added accounts follow an existing SNA standard, but others could be mainly custom-designed by an NSO for its own (limited) uses in local conditions. Ideally all extra national accounts or tables produced by an NSO should be internationally comparable, but that may not always be the case. The non-core accounts are in principle always optional (there are exceptions to this norm in the European Union). Whether extra accounts or extra tables are compiled and published by an NSO, depends mainly on their practical usefulness. NSO's produce them, if there is a need or demand for such accounts, and if there is a budget to produce the accounts. In some countries, it is not yet feasible to produce particular ancillary or satellite accounts, or it is too costly for them to do that.
Starting with the 1968 SNA revision, standards are provided for input-output tables (I/O tables) showing interactions between production sectors within the national economy (the enterprises of each sector make payments when they purchase inputs from other sectors, and receive revenue when they sell outputs to other sectors, so that the input and output values can be identified). The supply and use tables (SUT tables) [73] are a further development of the input-output analysis for which standards were first created in SNA 1993. These SNA tables provide a detailed breakdown of the origin and use of goods and services in the national economy. They show in matrix format the supply of goods and services from production and imports, and their destined uses (intermediate and final consumption, capital formation and exports). In the European System of Accounts (ESA 2010), it is compulsory for EU member states to provide both SNA standard input-output tables and SNA standard supply & use tables to Eurostat, with a deadline of three years. [74]
The term "satellite accounts" (comptes satellites) originated in France. [75] French statisticians created the first official satellite accounts in the late 1960s, initially with experimental housing accounts in 1968. By the 1970s, they had developed systematic satellite accounts for health, education, research & development, social protection, and transportation. [76] The goal was to provide detailed analyses of specific sectors to support government planning – maintaining consistency with the central national accounts framework, without altering it. [77]
The U.S. Bureau of Economic Analysis (BEA) developed auxiliary accounts for its NIPA framework already in the 1950s, but they were not called "satellite" accounts. [78] In the late 1980s, the demand for environmental accounts was met by the creation of satellite accounts. [79] The US Bureau for Economic Analysis officially adopted a satellite account framework for research & development in 1994 and later for tourism and the space economy, referring to SNA guidelines. [80]
Satellite accounts were officially recognized and defined for the first time in SNA 1993, and elaborated in SNA 2008. [81] [82] Several standards for satellite accounts are outlined in SNA 2008 and SNA 2025. Often more comprehensive explanations of standards and their application have been given in special handbooks, brochures or working papers. The OECD provides a guide to designing satellite accounts. [83] In 2019, a review suggested that satellite accounts had been implemented for 21 different topics, with another 11 account topics being planned. [84] Another source claimed that over 80 countries had implemented satellite accounts by 2019, with more than 20 different topics. [85] A 2020 survey about the national use of SNA satellite accounts discovered that 241 satellite accounts had been created by 80 countries for 20 different account topics. The number of satellite accounts per country varied from 1 to 15 accounts, with a median number of 2 accounts, and an average of 4 accounts. The countries with the most satellite accounts were Canada (15), Portugal (13), Israel (9), Australia (8), Finland (8), Lithuania (8), China (7), and Mexico (7). [86]
In SNA 2025, the term "satellite account" is formally abandoned in favour of the terms "thematic account" and "extended account". Thematic accounts disaggregate and rearrange already existing items in SNA core accounts, to make particular aspects of economic relations more visible and explicit. In other words, they provide extra details and breakdowns for the totals given in core accounts. Extended accounts go beyond the conceptual boundaries of the SNA integrated framework, often linking SNA accounting data to external data (for example, demographic data, geographic data, employment data, population data, data on natural resources), with the aim of enabling more comprehensive insight about a topic of interest. In such cases, SNA data is linked to non-SNA variables, following standard conventions to assist comparability. The SNA 2025 Manual enlarges the scope of macroeconomic accounting, and defines how SNA standards can be linked to non-SNA standards. For example, SNA 2025 recognizes four kinds of capital: economic capital, human capital, natural capital and social capital.
How the “largest national accounts” should be defined is debatable. [87] The criterion used here is population size, because as a general rule the larger the population is, the larger will be the volume and complexity of transactions and transfers that have to be accounted for. In 2025, the world's eight largest countries by population together had about 4.67 billion residents, which is equal to about 56.7% of the total world population. The United States and the European Union are included among the "largest accounts", because they produce integrated national accounts based on data from their member states.
India first introduced national income estimates in 1952, and has progressively integrated SNA updates in its National Accounting System (NAS), including the 1968, 1993, and 2008 revisions. NAS adheres broadly to SNA concepts (such as GDP, Gross Value Added, and sectoral accounts), but also uses country-specific methods to deal with data limitations, a large informal sector, and local administrative practices. India's Central Statistics Office (under the Ministry of Statistics and Programme Implementation) continues to revise the NAS to improve harmonization with SNA standards, but retains methods specially designed for Indian economic conditions. [88]
Annual SNA-based estimates for the People's Republic of China (excluding Hong Kong, [89] Macao [90] and Taiwan [91] ) were first produced for 1985. For 1985–1992, separate national accounts were compiled according to the Material Product System (MPS) and SNA 1993, although at that time the SNA data were mainly derived from MPS accounts (using a conversion method created by the United Nations Statistics Division). [92] In 1992, SNA was adopted by the National Bureau of Statistics of China as the official accounting system. From that time, the MPS system was abandoned, and Chinese national accounts were directly compiled in accordance with SNA principles. [93]
Eurostat uses a version of the SNA for the European Union, called the European System of Accounts (ESA). [94] Participation in the ESA system is mandatory for European Union member states. [95] All EU Member States are legally obliged to use ESA 2010 for their national and regional accounts. [96] This includes providing standardized macroeconomic data to Eurostat, consistent with the ESA framework. The ESA concepts are uniformly applied in budget reports by EU member governments and in their official financial statistics, as well as in EU financial surveillance systems for member governments. For example, according to the EU Stability and Growth Pact (SGP), EU government budget deficits must ordinarily not exceed 3% of GDP, and the norm for EU government debts (the public debt) is that they must not exceed 60% of GDP.
The American-designed National Income and Product Accounts (NIPA), used uniquely in the United States, feature broadly the same concepts as SNA, but they differ from the SNA in details of methodology, classifications and presentation. [97] The traditional similarity between the SNA and the NIPA exists, because the original design of the SNA in 1953 was to a certain extent modeled on the NIPA accounting system already adopted by the US federal government in 1947. [98] The subsequent SNA revisions were also informed or influenced by developments in the NIPA accounts. Since 1993, the American Bureau of Economic Analysis has made an effort to achieve greater conceptual consistency with SNA standards. [99] The differences in data and presentation between the two systems are not an insurmountable problem, because the NIPA and the SNA both provide sufficient information to rework statistics to match each other's concepts, categories and classifications.
The national accounts of Brazil, Indonesia, Pakistan and Nigeria (altogether home to about 988 million people in 2025, i.e. almost one billion) are all based on SNA concepts and methods, but with differences in the SNA versions used, implementation quality, and institutional capacity. The Brazilian Institute of Geography and Statistics (IBGE) uses SNA 2008, and is highly advanced in social accounting, with full implementation of institutional sector accounts, supply and use tables, quarterly national accounts and integration of satellite accounts (e.g., environmental accounts, health, and education). Statistics Indonesia uses SNA 2008, and its accounts are quite comprehensive. The Pakistan Bureau of Statistics uses SNA 1993 and SNA 2008, but complete data is not yet available for all standard SNA accounts. The National Bureau of Statistics, Nigeria (NBS Nigeria) uses SNA 2008, aiming to rebase the data sets to 2019. [100]
There exist numerous regional organizations which assist countries at different stages of statistical development to implement SNA accounting techniques. The World Bank tracks the level of statistical capacity for all countries of the world, and provides an overview. [101]
The United Nations Economic Commission for Europe (UNECE) set up in 1947 by the UN Economic and Social Council (ECOSOC) promotes the implementation of SNA in UNECE countries, especially in South-East European (SEE) countries and East European, Caucasus and Central-Asian (EECCA) countries. [102] UNECE maintains its own statistical database.
In Latin America and the Caribbean, there is the regional program Sistema de Cuentas Nacionales (SCN), coordinated by the Economic Commission for Latin America and the Caribbean (ECLAC) [103] together with the UNSD, IMF, and World Bank. Its aim is to organize, standardize and harmonize the implementation of SNA 2008 across the region. There are 33 participating countries.
The Caribbean Community framework (CARICOM) provides SNA technical cooperation for Antigua and Barbuda, Bahamas, Barbados, Belize, Dominica, Grenada, Guyana, Jamaica, Haiti, Montserrat, St. Kitts and Nevis, St. Lucia, St. Vincent and the Grenadines, Suriname, Trinidad and Tobago. It coordinates with UNSD and ECLAC on SNA 2008 implementation, with a special focus on tourism satellite accounts (TSA) and remittances.
The ASEAN Guidelines on National Accounts aim to improve SNA 2008 alignment, harmonize national accounts, strengthen capacity, and improve data quality and dissemination in the ASEAN region. The program involves 10 countries and is sponsored by ASEANstats, IMF, UN ESCAP, and Asian Development Bank (ADB). [104] The Statistical Institute for Asia and the Pacific (SIAP) of the United Nations Economic and Social Commission for Asia and the Pacific (ESCAP) as well as the United Nations Economic and Social Commission for Western Asia (ESCWA) provide trainings in SNA knowledge, and technical support for SNA implementation. [105]
In West Africa and Central Africa, there is the Economic and Statistical Observatory of Sub-Saharan Africa (AFRISTAT) created in 1993 by WAEMU countries and other associated countries. The organization promotes harmonized national accounts, following SNA 1993 and moving to SNA 2008 and SNA 2025. In East Africa and Southern Africa, there are regional organizations like Common Market for Eastern and Southern Africa (COMESA), Southern African Development Community (SADC), and East African Community (EAC) which have statistical committees supporting SNA implementation. These are backed by AfDB, the IMF's AFRITAC organizations, and the African Centre for Statistics in UNECA.
The GCC Statistical Center (GCCStat, Gulf Cooperation Council) coordinates statistical work, including national accounts, for Saudi Arabia, UAE, Qatar, Kuwait, Bahrain, and Oman. It is moving toward SNA 2008-compliant national accounts. The focus is now on non-oil sectors, satellite accounts, and price indices. Although it is not a UN organization, the Statistical, Economic and Social Research and Training Centre for Islamic Countries (SESRIC) works with the UN to support statistical capacity and socio-economic research in Islamic countries.
To support and harmonize the implementation of SNA across the Pacific region, several organizations provide technical assistance and capacity-building initiatives. Pacific Community's Statistics for Development Division offers guidance and training to enhance statistical systems. The Pacific Financial Technical Assistance Centre (PFTAC) aims to strengthen institutional capacities in macroeconomic and financial management, including national accounts statistics. The United Nations Economic and Social Commission for Asia and the Pacific (UNESCAP) conducts regional programs to improve economic statistics in Asia and the Pacific. In addition, the National Transfer Accounts (NTA) network is also active in the region.
Athough the OECD does play an important role in shaping the global statistical system, and has observer status in the United Nations, it is not counted here as a "regional organization". The reason is that geographically the OECD member states are not in "one region", but are spread across the whole world, from Chile to South Korea, from New Zealand to France and from the United States to Poland. So there is no exclusively "regional" mandate. Originally, the OECD really was a regional organization. It was called the Organisation for European Economic Co-operation (OEEC). That institution was founded in 1948 to administer American and Canadian aid under the Marshall Plan for the reconstruction of Europe after World War II. However, there are now many member countries of the OECD outside Europe, and the international role of the OECD has changed and expanded greatly. Now the OECD takes a global approach, working with more than a hundred countries to improve and advise on government policies, economic and business development, statistical analysis, social and environmental issues etc. Compiling comparative SNA data sets, providing macro-economic country analyses and advising on SNA methodology are only a part of a multitude of tasks that the OECD performs today, to help countries to advance.
No single agency has a monopoly on publishing SNA statistics. SNA statistical data as such is usually considered to be a public good, and its producers typically do not “own” the data they make publicly available (in the sense of copyright or patent rights). However, they do own intellectual property and access rights for the processes, methodologies, documents, databases and software used to compile, store, distribute and manage the statistical data (see e.g. Data Act (European Union) and EU Data Act, September 2025). [106]
There are few universal standards for how exactly SNA data are published, in print copy or digitally. There is no universal SNA logo, trademark, barcode or QR-code. NSO's typically publish SNA-type national data series using their own formats and styles. International organizations like the IMF, OECD, the World Bank and Eurostat often adjust national SNA data according to their own methodologies. International agencies will often include adjusted United States data sets in their comparative SNA statistics, even though the US has its own NIPA accounting system. Sometimes estimates for core variables are included for countries/areas which are at present still outside the SNA aegis.
Published SNA statistics can be freely used and cited by the public, provided that the source is acknowledged correctly by the user. More detailed accounts data at a lower level of aggregation is often available on request. Statistics offices typically provide a lot of information free of charge (as a government-funded public service). However, usually they do charge fees for (1) many printed and copyrighted publications, (2) the supply of specialized data sets, and (3) specialized data services. How exactly the boundary between paywall data and free data is drawn, and what the costs are, can vary from country to country. It may depend on who the data users are, what sort of data they want, how the data is used, and what the local laws and policies permit.
For particular sorts of SNA data sets, one national or international agency is usually the "primary" publisher. For example, international agencies are more likely to publish comprehensive international comparisons of SNA data on a regular basis (for example, UNSD, OECD, IMF, World Bank and Eurostat). Detailed national SNA statistics are usually available from national statistics offices (NSO's) or national governments. [107] Data users have the option of getting their national data sets either from NSO's or from intergovernmental organizations, or from some third-party source (such as central banks, economic research institutes or academic collections).
Economic and financial data produced by UN member countries are used to compile comparable annual (and sometimes quarterly) data on the gross product, national income, investment, capital transactions, government expenditure, and foreign trade. The results are published by NSO's, but also in two UN Yearbooks: (1) National Accounts Statistics: Main Aggregates and Detailed Tables and (2) National Accounts Statistics: Analysis of Main Aggregates. From 2025 onward, the yearbooks are published in line with the SNA 2025 standards. The values provided for the accounts of individual countries in the UN yearbooks are cited in the national currency.
Current and constant US dollar equivalents can be found in the online UN National Accounts Main Aggregates Database. Additional variables can be accessed online in the UNdata Portal. Alternative sources of GDP and its components in US dollars at current and constant prices are the World Development Indicators (WDI) of the World Bank, and the World Economic Outlook Database of the IMF. Both the World Bank and the IMF use exchange-rate converted GDP estimates and PPP-adjusted measures. The IMF publishes comprehensive SNA-based Balance of Payments statistics for the world's countries, as well as comparative statistics on government finance. The OECD [108] and the World Bank publish a lot of SNA-based comparative economic statistics, country reports and regional reports. To make the comparisons, the data series often have to be converted to a common currency (usually US dollars).
National accounts data is susceptible to revision. A very large number of different data sources, entries and estimation procedures are involved that can have impact on the totals. Discrepancies can occur between the totals cited for the same accounting period in different publications issued in different years. The "first final figures" may later be revised, sometimes several times. The revisions may be quantitatively slight, but cumulatively across e.g. ten years they can sometimes alter a trend significantly. The researcher has to bear all this in mind when seeking to obtain consistent and up-to-date data series. Often it is possible to link old and new data series using some suitable chaining method. The possibility of data revisions are a good reason for correctly citing the source of the data.
SNA data quality is relatively good, because there are data standards, and because the data are regularly checked and monitored by several agencies, not just by the data producers. Nevertheless, the data sets of some countries are much more complete than others. Both the quality and the comprehensiveness of national accounts data can differ between countries. There are six main reasons:
The United Nations and its partners have rather little power to enforce the actual production of statistics to a given standard, even if international agreements are signed by member states. But they can help with technical advice, training and capacity building. The UNSD collects and archives national accounts statistics from most of the world's countries and territories. [111] Some of the world's states are part of other international/interstate unions (for example the European Union, the OECD, or the United States), which oblige member states to supply standardized data sets, for the purpose of interstate or international comparisons and coordination. In exchange for supplying data, countries can also receive foreign data and expert scientific advice. So there are incentives and benefits for countries to cooperate, for the sake of obtaining more useful, comprehensive, and internationally comparable statistical information. If they cooperate, countries can obtain vastly more foreign statistical information and expertise at a lower cost, which matters if the information is essential to have for local, national and international decision making. The bottom line for the quality of official national accounts data is adequate funding and staffing, cooperation and trust. [112] ).
SNA continues to be developed further. International conferences are regularly held to discuss various conceptual and measurement issues, and proposed revisions. This is necessary, because the world changes, [113] new data needs emerge, new coordination/integration challenges arise, and new production techniques become available. [114] The proposed SNA 2025 provides for many new standards and supplementary SNA tables on different topics. [115] Many of the new supplementary tables aim to link SNA financial data with social or physical statistics from other international or national agencies, with the aim of providing standardized, comparable national data sets on specific topics (such as labor use, natural resources, productivity, health etc.).
There are many ongoing projects, such as developing standard accounts for environmental resources, [116] the measurement of the trade in various services and of productivity, the treatment of insurance payments, the grey economy and informal economy, employee compensation in the form of non-wage income, intangible capital, cryptocurrencies, labor economics etc. Projects related to the SNA 2025 revision are mentioned on the UNSD webpage. [117]
Revisions of the SNA national accounts system are normally coordinated by the Intersecretariat Working Group on National Accounts (ISWGNA), comprising representatives from the United Nations Statistics Division (UNSD), International Monetary Fund (IMF), World Bank (WB), Organisation for Economic Co-operation and Development (OECD), Statistical Office of the European Communities (Eurostat) and the United Nations regional commissions. The ISWGNA working group has its own website under the UN Statistics Division [118] and works with the Advisory Expert Group (AEG). [119]
Discussions and updates are reported in the news bulletin SNA News and Notes. [120] Official SNA revisions are always documented at the UN Statistics Division site. [121] For the 2008 SNA revision, the full final text is available online. [122] For the 2025 Revision, only the pre-edit document is available so far; the final official text still has to be approved and published. [123] The pre-edit version of SNA 2025 shows which text from SNA 2008 is revised, and which text is a new addition to SNA guidelines.
The achievements of SNA, and why they matter, can be summarized as follows:
SNA data is used every day by millions of public servants, private sector data professionals, businesspeople, media and academics worldwide. Without SNA data (whether published by the UN, or published by other agencies), they would not have the internationally comparable economic data they require. So the data users appreciate that the information is available. However, SNA has also been criticized for its shortcomings. [124] That is to be expected — with so many users of SNA data worldwide, and given the limits of what the SNA accounts can provide for different countries, it is simply impossible to satisfy everybody's economic data needs all of the time. For example, it has been argued that SNA should include measures of happiness, but this idea has never been implemented. [125] There do already exist international happiness measures, such as the World Happiness Report, which can be compared with SNA economic variables. [126] The United Nations introduced the Human Development Index in 1990 specifically because it was felt that economic indicators alone are insufficient to assess human development; economic indicators do not necessarily express the average quality of life of a country's residents.
The criticism most often made of SNA is that its design, concepts and classifications do not adequately reflect the interactions, relationships, and activities of the real world. [127] The effect of that is (allegedly) a distorted picture of the world. For example, there are the following sorts of criticisms:
SNA authorities have responded to such criticisms in many different ways, large and small.
In the last decades, there are constantly many efforts across the world to standardize statistical data to make them internationally comparable, with equal or similar data quality. SNA was created specifically as a tool for measuring changes in economic activity, national income and economic growth in a standard way, which enables international comparisons. SNA was not designed to include “everything we need to know about a country or about the world”, and it is impossible for SNA to do that. SNA design is a compromise involving many different concerns and interests, but it aims to be the best possible compromise that is currently feasible. There are many data topics which, although they are not included in the SNA framework, are already covered elsewhere by other United Nations agencies or by its partner organizations.
As regards current topics of interest, the United Nations is often already developing concepts & methods for statistical information (e.g. Islamic banking [131] ), or there is already an UN agency which supplies data (e.g. UNCTAD provides data on multinational/transnational corporations). Furthermore, a lot of SNA data that seems to be "not available" can be obtained simply by digging deeper into the detailed breakdowns of the SNA tables. Quite often, there exists much more SNA statistical information than most data users actually use.
Many concerns about unmet data needs are being addressed via the design of supplementary SNA standard tables or SNA satellite accounts (thematic and extension accounts), which provide modified SNA aggregates for special uses, or which integrate SNA accounts data with social, demographic, financial or environmental data from other sources. The advantage of this approach is that the comparability with traditional SNA accounts and previous SNA data is not jeopardized by constant revisions to accommodate new data demands.
SNA requires standard, comparable accounting formats, and its design has a specific, limited statistical purpose. Some types of data production simply do not fit with that structure and purpose (but SNA data could be combined with data from other sources). The SNA 2025 manual provides standard conceptual frameworks to address the majority of the contemporary concerns and data needs, clearly distinguishing between what SNA can contribute and the integration or matching of the SNA framework with non-SNA standards. It is primarily the responsibility of the NSO's to take the initiative to produce new and additional data that is consistent with the new SNA 2025 frameworks for various new topics, if they consider it important to create that data, in the present or in the future.
Particularly in OECD countries, a great effort has been made by NSO's to supply timely SNA data which is accurate and complete, and which does not have to be revised very much afterwards. Modern technology increasingly makes possible much faster data collection, processing and publication, because it can be done with digital and online questionnaires (sometimes using mobile phones); digital coding; data warehouses; automated searching, editing, error-tracking and dataset construction; automating procedures with artificial intelligence, etc. Aided by modern computers, data production can often be realized faster, more efficiently, with fewer errors and better quality. This is especially important in countries with very large survey populations (for example, Brazil, China, Germany, India, Indonesia, Japan, Nigeria, Russia, and the United States).
Statisticians do their best to safeguard the autonomy, objectivity, quality and integrity of data production and data releases, with specific professional protocols and the provision of explanations to the public about significant statistical trends. [132] There are now more and more different ways to make data available to users, and much more attention is being given to information design to make data understandable. [133] Often vastly more data is available than is actually used for empirical investigation by researchers.
In the digital era, people have to process much more information in much less time. To do this, they have to be able to find/navigate through records, data sets and documents faster. There is growing awareness that good, thoughtful information design saves time, effort and money. It also prevents eyestrain and headaches. Data means nothing, if it is not communicated in an effective way so that people can understand it. [134]
The most popular criticism of national accounts concerns the concept of gross domestic product (GDP). GDP has been criticized from all sides for what it does not measure, or because it allegedly mismeasures the national economy. Economists like Joseph Stiglitz argued that a measure of "well-being" was needed to balance a measure of output growth. [135] Such measures were designed, but so far they have not been used much in national SNA accounts. SNA 2025 does broaden the national accounts framework, to account better for elements affecting wellbeing and sustainability, and to inform various policy goals of governments and international organizations. According to Stiglitz, one of the paradoxes of GDP measurement is that:
“…while GDP is supposed to measure the value of output of goods and services, in one key sector — government — we typically have no way of doing it, so we often measure the output simply by the inputs. If government spends more — even if inefficiently — output goes up.” [136]
In part, the criticism of GDP is misplaced, because the fault is not so much with the concept itself. It is useful to have measures of the value of a country's total net output and measures of national income, showing their changes over time – that's better than having no measures at all. The fault is more with the actual use that is made of the concept by governments, intellectuals, the media and businessmen in public discourse. [137]
GDP measures are frequently misused by writers who do not understand what the measures mean, how the measures were produced, or what the measures can be validly used for. Many of the critics of SNA have no real knowledge about the main purpose of SNA, never mind understanding the possibilities and limits of the accounting design. GDP is used for an enormous diversity of comparisons, but many of those comparisons may conceptually lack validity or are not appropriate.
In the US, for example, it is very common for politicians and the media to equate GDP with "the economy", but this is plainly false — GDP does not measure all economic activity, it is only a measure of the new gross value added generated by production of goods and services during an interval of time (the net value of a country's output) which, in the SNA accounts, equates to certain measures of national income/expenditure. [138] All economic activities, transactions and incomes which are outside the SNA production boundary (for example, asset trades, receipts of property income, transfers and capital gains) are not included in Gross Output and GDP.
For another example, a popular statistic is "public debt as a percentage of GDP". This debt/GDP ratio could be understood (wrongly) to mean that the public debt, or its annual repayment, is a component of expenditure on GDP, or that it represents the size of national income currently required to pay off the national debt. What this debt/GDP ratio ignores, is that the coverage of the public debt variable and the coverage of the GDP variable are quite different. GDP includes only flows of incomes/expenditures and taxes considered to be inside the production boundary, i.e. flows directly generated by production. GDP does not include all the revenues and expenditures of the government, it does not include all the revenues and expenditures in the economy, and it is not a measure of assets or liabilities. The debt/GDP ratio says nothing about the amount of principal and interest that must repaid per year or per quarter. To assess a financial position, debt liabilities incurred must in principle always be related to the total assets held and the total revenues from which the debt can be repaid. It must be made clear how much must be paid each year or quarter to repay the debt (which is usually not the whole sum). If (say) a couple applies for a home mortgage loan from a bank, the bank usually wants to know much more financial information than just their annual net salary from work. To assess the total "mortgage" of the whole national economy, both public debt and private debt has to be considered — quite often, and particularly in developed countries, private debt exceeds public debt, by a large margin.
The main response by statistical authorities to the criticism and misuse of GDP data has not been to abandon or abolish the GDP measure. [139] Instead, statisticians have provided additional, complementary data sets about phenomena which GDP does not measure, and cannot measure. [140] With this approach, most data users can get the data that they want, most of the time, without denying the data needs of other users. There are official limits to the varieties of data that can be made available, but with the aid of modern technology, a vastly greater variety of data can be made accessible to the public, at the touch of a button.
SNA has been criticized as biased by feminist economists such as Marilyn Waring, [141] Maria Mies, [142] Lourdes Benería, [143] and Nancy Folbre, [144] because no imputation for the monetary value of unpaid housework or for unpaid voluntary labor (mainly done by women) is made in the accounts, even although GDP does include things like the "imputed rental value of owner-occupied dwellings" [145] and an imputation for "financial intermediation services indirectly measured" (FISIM). This SNA omission of unpaid housework (because it falls outside the SNA "production boundary" [146] ) is said to obscure the reality that market production depends to a large extent on non-market labor being performed. [147] In turn, that lacuna in the data allegedly promotes a distorted picture of economic life (which in reality includes both paid and unpaid work). [148]
However, such criticism does raise technical issues [149] for the statisticians who would have to produce the standard data, such as:
The intention of those who would like to produce standard data for the imputed market value or imputed cost of women's voluntary labor can be perfectly honorable. Many scientific studies already exist on the subject. [153] However, the production and cost of creating this data every year, as a standard procedure, has to be justifiable in terms of scientific feasibility and practical utility. It could be argued that attaching an imputed price to housework as a standard international procedure, might not be the best data to have about housework. It míght not make people who do housework more valued in the eyes of others, and it might not result in a general improvement of social attitudes and behaviour. There is certainly a permanent need for data on housework and voluntary work, because (as surveys prove) so many people are involved in it. But SNA might perhaps not be the best place to supply that data. There have nevertheless been quite a few proposals for a standard SNA satellite account for household labour [154] ).
The (pre-edit) SNA 2025 manual provides a definitive solution: it revises and refines the concepts for the analysis of the household economy; it encourages countries to develop extended accounts for unpaid household service work (in chapter 1 §64); recognizes the importance of the household economy for wellbeing (in chapter 2 §56-61); fully integrates voluntary and unpaid labour into labour accounting (in chapter 16); and specifies the standard conceptual structure and formats of accounts for "unpaid household service work" in chapter 34 §83-103. So this is a win for the feminist movement. However, the creation of such satellite accounts by NSO's remains optional and voluntary, not compulsory or obligatory. It does not necessarily mean that all countries will now regularly produce such accounts, using exactly the same measurement techniques.
In most OECD countries so far, statisticians have usually estimated the value of housework using data from time use surveys. [155] The valuation principle applied is usually that of how much a service would cost on average, if it was purchased at market rates, instead of being voluntarily supplied. Sometimes an "opportunity cost" method is also used: in this case, statisticians estimate how much women could earn in a paid job, if they were not doing unpaid housework. [156] Robert Eisner estimated that the market value of unpaid housework in money terms was equivalent to about 33% of the value of US GDP in 1981. [157] Nancy Folbre provides more recent comparative data. [158]
When she was the head of the International Monetary Fund, Christine Lagarde reportedly claimed at an IMF/World Bank annual meeting in Tokyo (October 2012) that women could rescue Japan's stagnating economy, if more of them took paid jobs instead of doing unpaid care work. A 2010 Goldman Sachs report had calculated that Japan's GDP would rise by 15 percent, if the participation of Japanese women in the paid labor force was increased from 60 percent to 80 percent, matching that of men. [159]
However, domestic and care work would still need to be done by someone, meaning that either women and men would need to share household responsibilities more equally, or that parents would have to rely on childcare and eldercare supplied by paid caregivers from the public sector, or from the private sector (nursemaids, au pairs, nannies, domestic helpers etc.). Many mothers don't care about a GDP number from a statistics office, they care about their children, and do not want to outsource their parenting. With a greying population, the economy will need more children that can replace retired workers in the future; that makes raising children properly a priority (particularly in the first five years of life). The majority of young people with young children cannot afford to hire caregivers themselves, and would have to rely on young volunteers or low-paid assistants. [160]
According to later IMF data, the female "labor-force participation rate" for paid work in Japan did rise from 63 percent in 2012 to 74 percent in 2023, [161] but estimates of the added contribution to GDP were not very large. [162] The explanation is most probably that while many Japanese women do work in paid jobs, they often work part-time or in non-regular jobs, with lower pay and shorter hours; in Japan there is still a large gender pay gap [163] ). According to the OECD Gender Dashboard, Japan's gender pay gap slightly widened from 21.3% in 2022 to 22% in 2023, while the OECD average stabilized around 11%. As a result, Japan ranks 35th out of 36 OECD countries in terms of pay equity. [164]
According to the International Labour Organization (ILO), about 75.6 million domestic workers are employed in the world, mostly women and migrants, representing 4.5% of all workers (among every 22 workers, one worker is a domestic worker). In terms of their social status, domestic workers remain largely "undervalued, underprotected, and underrepresented". In 2021, the ILO estimated that 81% of all domestic workers were "informally" employed. [165] They are mainly servants of wealthy people and the professional middle classes.
The laments and revolts of women about their domestic roles have a very lengthy history, but the modern theoretical discourse about women's unpaid household labour originated among the European, British, and North American Left at the beginning of the 1970s. [166] Some of the main leftwing criticisms of SNA concepts are that:
One result of the SNA accounting concepts is that workers' earnings are overstated in the production account, since the account shows the total labor costs to the employer rather than the "factor income" which workers actually receive at the time. If one is interested in what incomes workers – the people who produce the wealth – actually get, how much they own, or how much they borrow, SNA national accounts may not provide the required information, or a special disaggregate analysis may be necessary to find that out (in the US, the NIPA's and BLS data provide more details about workers' incomes). At the same time, total business profits are understated in the production account, because true profit income in a country is larger than operating surplus. The most important reason is that many profits fall outside the SNA-defined production boundary of the production account. Ten specific aspects can be mentioned:
SNA statisticians acknowledge that alternative measures of gross product, income/expenditure, capital accounts and external transactions accounts are always possible. Considerable opportunities exist for researchers to reaggregate/rework existing official SNA statistics, to create their own alternative measures for their own analyses and interpretations. However, the SNA statistical framework is designed primarily to provide standard, comparable measures, not "non-standard measures" (or all sorts of non-standard interpretations) which may or may not be valid in specific situations. Sometimes NSO's themselves produce "non-standard" data sets alongside standard data sets, because government departments request such data for a particular project (it is less likely, in this case, that the non-standard data sets would be published like other official statistics, except perhaps some data series cited in the project report).
A few examples of an alternative "non-standard" approach are:
The SNA 2025 manual provides a more detailed conceptual structure to account for the transactions of labour and employment, and it creates the option for extra satellite accounts for labour variables. Future SNA satellite accounts may address some of the leftwing concerns raised, via satellite accounts, on topics such as labor inputs, income distribution and activities of the financial sector.
Originally, SNA was designed to provide standard, internationally comparable measures for the magnitudes and changes in national income, output, spending, capital formation and external transactions. All of these indicators are essential to understand the causes and patterns of economic growth, and to provide insight about economic trends. However, that approach is now often deemed to be inadequate (and for some, totally wrongheaded — see for example degrowth), because it leaves out crucial variables, such as environmental variables which impact on the whole economy. [180]
The technical discussions about the inclusion of environmental variables in SNA accounts have carried on for more than half a century since the 1972 Limits to growth report of the Club of Rome. Nowadays a very large scientific literature exists about the subject. [181] However, for many years it proved difficult to reach (i) a workable international consensus about (ii) a feasible SNA methodology, (iii) to create meaningful environmental accounts that could be (iv) international standard SNA accounts which are both (v) useful for policymaking and (vi) internationally comparable (keeping in mind the great diversity of environmental conditions in 200+ different countries and territories) while (vii) maintaining the continuity of SNA core accounts. Given that a very large amount of data is already being collected about the environment, the central issue for SNA statisticians became what specific contribution SNA accounting could usefully add to the total statistical picture of the natural environment that was emerging.
Ten sorts of environmentalist criticisms were made of alleged deficiencies in SNA accounts. [182] Most of these criticisms were about things that were traditionally not accounted for by SNA, but which (it was argued) ought to be accounted for as a standard procedure.
Each of these ten concerns was elaborated and debated in much more detail by many different researchers. [184] However, dealing with this large international scientific discussion goes beyond the scope of this article. [185] Simply said, across the last half century, the SNA framework has gradually recognized environmental concepts and methods of environmental accounting, and integrated them in the SNA accounting framework. But even if the concepts are now present, there may not be complete agreement ýet about the appropriate measurement techniques to obtain empirical estimates for the concepts.
The development of SNA environmental accounting standards can be briefly sketched as follows:
What SNA environmental accounting concretely involves for an NSO, is usefully described for example in a recent text on the subject by Statistics New Zealand. [193] It is quite possible that many environmentalists will still not be satisfied with the worldwide efforts of SNA statisticians, and that environmentalist criticism of SNA hasn't finished yet (see also greenwashing). Nevertheless, there is substantial evidence that a lot of scientific progress has been made across half a century to create standard accounting methods for natural resources. Not all the measurement issues have been resolved yet, but international discussion/consultation is continuing. [194] At least a basic SNA accounting framework for environmental variables now exists. [195]
It remains to be seen to what extent NSO's across the world will include SEEA in their national statistics as a standard practice. [196] Environmental accounting is in principle optional for UN member countries, although in Europe, NSO's are required by EU regulations to compile a few specific modules in SEEA, as a standard practice (air emissions, environmental taxes by type, and material/energy flows). [197] Most high-income countries began to compile SEEA accounts in the 2010s. [198] In early 2025, at least 94 countries had created “at least one SEEA account” within the last five years. Of these 94 countries, 67 countries are said to be compiling and publishing at least one SEEA account "regularly". [199]
Both the strengths and the weaknesses of national accounts are, that they are based on an enormous variety of data sources. The strength consists in the fact that a lot of cross-checking between data sources and data sets can occur, to assess the credibility of the estimates for the bigger picture. In each account, things do have to "add up" correctly, and the different accounts have to be mutually consistent. The weakness is, that the sheer number of inferences made in compiling data sets increases the possibility of data errors, and can make it more difficult to trace the causes of errors.
Statisticians sometimes comment on the limitations of international comparisons using national accounts data, on the ground that in the real world, the SNA estimates are rarely compiled in a truly uniform way – despite appearances to the contrary. [200] People often assume that the data are "precisely accurate", although the data may only be a "best estimate" under the given conditions, or "approximately true" and "indicative". It can happen that the reported percentage change in a macroeconomic variable is equal to the possible margin of error in the statistical estimates for that variable. There is often little official transparency about data errors in national accounts. [201]
Jochen Hartwig once provided evidence to show that "the divergence in growth rates [of real GDP] between the U.S. and the EU since 1997 can be explained almost entirely in terms of changes to deflation methods that have been introduced in the U.S. after 1997, but not – or only to a very limited extent – in Europe". [202]
According to Steve McFeely, the chief statistician of the OECD,
“As of 2022, the UN Statistics Division reported that only two thirds of countries worldwide had implemented the 2008 SNA guidelines… posing uncomfortable questions as to what it really means to adopt a statistical standard… only about half of all countries compile their GDP estimates using all three (income, expenditure, and production) approaches. Moreover, only a selection of countries currently compile comprehensive balance sheets that include non-produced non-financial assets, such as natural resources.” [203]
NSO's in the OECD member countries are generally much further ahead with their national accounts than NSO's in many developing countries. Developing countries don't have the same resources, facilities, staffing and socio-political stability that most OECD countries can offer (see World Bank Statistical Performance Indicators (SPI) and the World Bank Statistical Capacity Building site). [204] Consequently, developed and developing countries tend to differ in their priorities for producing national statistics. If 130+ countries did implement SNA 2008, that could also be viewed as an astounding political and mathematical success, given that those countries include the great majority of the world population. [205]
The "magic" of national accounts is, that they provide an instant source of detailed international comparisons. [206] However, critics argue that, on closer inspection, the numbers are often not really so comparable as they are made out to be. The practical result can be that all sorts of easy comparisons are tossed around by policy scientists, which, if the technical story behind the numbers was told, would never be attempted, because the comparisons are scientifically not credible. Had there been better education in the use of economic data, a lot of controversies would probably have been resolved quickly, or they would not occur. The counterargument is, that because countries are applying the same statistical standards and concepts, this already makes an enormous positive difference to data comparability. This positive difference far outweighs the effects of remaining methodological discrepancies in the data of different countries.
SNA data producers do not have control over how SNA data will be used. NSO's and intergovernmental organizations only control what information is released, how it is released and when it is released. They act in accordance with a legal framework, and follow directives from the officials in charge. The data can be used for purposes which are not valid, or used for purposes which the data were never meant to serve. [207] That is not the fault of SNA producers, but a matter of data awareness, statistical literacy, scientific debate and data user education. [208]
SNA data quality has been criticized, on the ground that what pretends to be "economic data" may involve extrapolated estimates using mathematical models, and not direct observations. These econometric models are designed (sometimes with great ingenuity) to predict what particular data values ought to be, based on sample data for "indicative trends". One can, for example, observe that if variables X, Y, and Z go up, then variable P will go up as well, in a specific proportion. In that case, one may not need to survey P or its components directly, it is sufficient to get available trend data for X, Y, and Z and feed them into a mathematical model, which then predicts what the values for P will be at each interval of time; at a later stage, the estimates from the model can be checked for their accuracy against relevant new data when it becomes available.
Because statistical surveys can be costly or difficult to organize, or because the data has to be produced quickly to meet a deadline, [209] statisticians often try to find cheaper, faster, and more efficient methods to produce the data. They make use of inferences from data that they already have, or from selected data which they can get more easily. Sometimes this procedure can be proved to supply accurate data successfully. But the purist objection to this approach is often that there is a loss in data accuracy and data quality.
Statisticians do admit that data errors and inaccuracies are possible, it is an occupational risk and a challenge. It would be preferable to have comprehensive survey data available as a basis for estimation. But they would argue that it is usually possible to find estimation techniques that keep margins of error within acceptable bounds. The real problem may be, that errors can be corrected only quite some time after the publication deadline, in the light of fresh data or additional data (cf. the Bureau of Labor Statistics controversy about large after-the-fact revisions of monthly estimates which are used as short-term economic indicators).
The 2024/2025 budgetary crisis of the United Nations has an impact on statistical work across the UN (cutbacks in staffing and technical assistance services; project delays and the shelving of flagship projects; data quality risks; insufficient funding for reporting, classification upgrades, and outreach), and that affects the entire global statistical community. [210] If governments refuse to pay for the production of high quality statistics with qualified staff, statisticians can only do what they are able to do, with the techniques and resources they have. Imperfect statistics may be better to have, than no statistics at all. In the future, digital technology and artificial intelligence will most likely make the production of economic statistics easier, cheaper, faster and better. [211] In particular, artificial intelligence can potentially provide much faster data error detection and error correction. However, artificial intelligence is not a panacea and it may introduce new errors in information systems: “Hundreds of Wikipedia articles may contain AI-generated errors. Editors are working around the clock to stamp them out.” [212]
Criticism can always be made of SNA, and that will probably continue. [213] SNA statisticians make criticisms themselves, although they may not do so publicly (because they lack authorization to do so). However, in the end people do want to have comparable macroeconomic data, to understand the proportions and magnitudes of economic situations. This macroeconomic data has to be produced by somebody, and it must be supplied according to deadlines. When it is published, it can have a strong effect on investment decisions, business activity and government policy. So NSO's and international suppliers of economic statistics are always under pressure to provide data of the highest possible quality, always on time. [214]
If data users are not satisfied with the data they get, they may be able to create their own data sets, starting out from publicly available information supplied by statistical agencies. Behind the published statistical totals, there also exist databases, archives and registers with more detailed information used to compile the totals. With appropriate authorization, it may sometimes be possible to obtain extra data and more detailed information. Usually the NSO staff is willing to help, [215] within the constraints of the relevant laws and rules, and professional protocols.
A great advantage of modern digital technology and digital data storage is, that data users are in principle no longer restricted to just one set of published official SNA accounts — it is technically possible for specialists with a specific research purpose to generate many account variants (or alternative accounts), by reaggregating, rearranging and recalculating SNA data in a spreadsheet. [216] In this sense, Rodney Edvinsson comments that "there is no point in replacing the current System of National Accounts", and that statistical offices should preserve data continuity, but also make available "as much disaggregated data as possible, so as to allow alternative constructions of national accounts".
