The gross world product (GWP) is the combined gross national income of all the countries in the world. Because imports and exports balance exactly when considering the whole world, this also equals the total global gross domestic product (GDP). According to the World Bank, the 2013 nominal GWP was approximately 75.59 trillion United States dollars. In 2017, according to the CIA's World Factbook, the GWP was around $80.27 trillion in nominal terms and totaled approximately 127.8 trillion international dollars in terms of purchasing power parity (PPP). The per capita PPP GWP in 2017 was approximately 17,500 international dollars according to the World Factbook. According to the World Bank, the 2020 GWP in current dollars was approximately $84.705 trillion.
Purchasing power parity (PPP) is the measurement of prices in different countries that uses the prices of specific goods to compare the absolute purchasing power of the countries' currencies, and, to some extent, their people's living standards. In many cases, PPP produces an inflation rate equal to the price of the basket of goods at one location divided by the price of the basket of goods at a different location. The PPP inflation and exchange rate may differ from the market exchange rate because of tariffs, and other transaction costs. The Purchasing Power Parity indicator can be used to compare economies regarding their GDP, labour productivity and actual individual consumption, and in some cases to analyse price convergence and to compare the cost of living between places. The calculation of the PPP, according to the OECD, is made through a basket of goods that contains a "final product list [that] covers around 3,000 consumer goods and services, 30 occupations in government, 200 types of equipment goods and about 15 construction projects".
A country's gross government debt is the financial liabilities of the government sector. Changes in government debt over time reflect primarily borrowing due to past government deficits. A deficit occurs when a government's expenditures exceed revenues. Government debt may be owed to domestic residents, as well as to foreign residents. If owed to foreign residents, that quantity is included in the country's external debt.
Government spending or expenditure includes all government consumption, investment, and transfer payments. In national income accounting, the acquisition by governments of goods and services for current use, to directly satisfy the individual or collective needs of the community, is classed as government final consumption expenditure. Government acquisition of goods and services intended to create future benefits, such as infrastructure investment or research spending, is classed as government investment. These two types of government spending, on final consumption and on gross capital formation, together constitute one of the major components of gross domestic product.
The economy of the European Union is the joint economy of the member states of the European Union (EU). It is the third largest economy in the world in nominal terms, after the United States and China, and the third one in purchasing power parity (PPP) terms, after China and the United States. The European Union's GDP was estimated to be around $17.9 trillion (nominal) in 2020, representing around one sixth of the global economy.
Canadian government debt is the liabilities of the government sector. For 2020, the market value of financial liabilities, or gross debt, was $2,852 billion for the consolidated Canadian general government. As a ratio of GDP, gross debt was 129.2% in 2020, the highest level ever recorded.
