A data set is a collection of data. In the case of tabular data, a data set corresponds to one or more database tables, where every column of a table represents a particular variable, and each row corresponds to a given record of the data set in question. The data set lists values for each of the variables, such as height and weight of an object, for each member of the data set. Each value is known as a datum. Data sets can also consist of a collection of documents or files.
The United States Census Bureau (USCB), officially the Bureau of the Census, is a principal agency of the U.S. Federal Statistical System, responsible for producing data about the American people and economy. The Census Bureau is part of the U.S. Department of Commerce and its director is appointed by the President of the United States.

Data analysis is a process of inspecting, cleansing, transforming, and modeling data with the goal of discovering useful information, informing conclusions, and supporting decision-making. Data analysis has multiple facets and approaches, encompassing diverse techniques under a variety of names, and is used in different business, science, and social science domains. In today's business world, data analysis plays a role in making decisions more scientific and helping businesses operate more effectively.
A data library, data archive, or data repository is a collection of numeric and/or geospatial data sets for secondary use in research. A data library is normally part of a larger institution established for research data archiving and to serve the data users of that organisation. The data library tends to house local data collections and provides access to them through various means. A data library may also maintain subscriptions to licensed data resources for its users to access the information. Whether a data library is also considered a data archive may depend on the extent of unique holdings in the collection, whether long-term preservation services are offered, and whether it serves a broader community. Most public data libraries are listed in the Registry of Research Data Repositories.
Research data archiving is the long-term storage of scholarly research data, including the natural sciences, social sciences, and life sciences. The various academic journals have differing policies regarding how much of their data and methods researchers are required to store in a public archive, and what is actually archived varies widely between different disciplines. Similarly, the major grant-giving institutions have varying attitudes towards public archival of data. In general, the tradition of science has been for publications to contain sufficient information to allow fellow researchers to replicate and therefore test the research. In recent years this approach has become increasingly strained as research in some areas depends on large datasets which cannot easily be replicated independently.
The National Bureau of Statistics, abbreviated as NBS, is an deputy-cabinet level agency directly under the State Council of the People's Republic of China. It is responsible for collection, investigation, research and publication of statistics concerning the nation's economy, population and other aspects of the society. Ning Jizhe is the commissioner of the bureau since 2016.
The Ministry of Statistics and Programme Implementation (MoSPI) is a ministry of Government of India concerned with coverage and quality aspects of statistics released. The surveys conducted by the Ministry are based on scientific sampling methods.
The National Transportation Library (NTL) maintains and facilitates access to information necessary for transportation decision-making in government and coordinates with public and private transportation libraries and information providers to improve information sharing among the transportation community. It is currently under the administration of the Bureau of Transportation Statistics (BTS).
The Bureau of Safety and Environmental Enforcement is an agency under the United States Department of the Interior. Established in 2011, BSEE is the lead agency in charge of improving safety and ensuring environmental protection relating to the offshore energy industry, mainly natural gas and oil, on the United States Outer Continental Shelf (OCS). The agency exercises the safety and environmental enforcement functions formerly under the Minerals Management Service including the authority to inspect, investigate, summon witnesses and produce evidence, levy penalties, cancel or suspend activities, and oversee safety, response, and removal preparedness.
The Energy Citations Database (ECD) was created in 2001 in order to make scientific literature citations, and electronic documents, publicly accessible from U.S. Department of Energy (DOE), and its predecessor agencies, at no cost to the user. This database also contains all the unclassified materials from Energy Research Abstracts. Classified materials are not available to the public. ECD does include the unclassified, unlimited distribution scientific and technical reports from the Department of Energy and its predecessor agencies, the Atomic Energy Commission and the Energy Research and Development Administration. The database is usually updated twice per week.
Google Public Data Explorer provides public data and forecasts from a range of international organizations and academic institutions including the World Bank, OECD, Eurostat and the University of Denver. These can be displayed as line graphs, bar graphs, cross sectional plots or on maps. The product was launched on March 8, 2010 as an experimental visualization tool in Google Labs.
The Observatory of Economic Complexity (OEC) is a data visualization site for international trade data created by the Macro Connections group at the MIT Media Lab. The goal of the observatory is to distribute international trade data in a visual form. At present the observatory serves more than 20 million interactive visualizations, connecting hundreds of countries to their export destinations and to the products that they trade.
Data science is an inter-disciplinary field that uses scientific methods, processes, algorithms and systems to extract knowledge and insights from structured and unstructured data, and apply knowledge and actionable insights from data across a broad range of application domains. Data science is related to data mining, machine learning and big data.
ICPSR, the Inter-university Consortium for Political and Social Research, was established in 1962. An integral part of the infrastructure of social science research, ICPSR maintains and provides access to a vast archive of social science data for research and instruction. Since 1963, ICPSR has offered training in quantitative methods to facilitate effective data use. The ICPSR Summer Program in Quantitative Methods of Social Research offers a comprehensive curriculum in research design, statistics, data analysis, and methodology. To ensure that data resources are available to future generations of scholars, ICPSR curates and preserves data, migrating them to new storage media and file formats as changes in technology warrant. In addition, ICPSR provides user support to assist researchers in identifying relevant data for analysis and in conducting their research projects.
Common Operational Datasets or CODs, are authoritative reference datasets needed to support operations and decision-making for all actors in a humanitarian response. CODs are 'best available' datasets that ensure consistency and simplify the discovery and exchange of key data. The data is typically geo-spatially linked using a coordinate system and have unique geographic identification codes (P-codes).
Datacommons.org is an open knowledge repository hosted by Google that provides a unified view across multiple public datasets, combining economic, scientific and other open datasets into an integrated data graph. The Datacommons.org site was launched in May 2018 with an initial dataset consisting of fact-checking data published in Schema.org "ClaimReview" format by several fact checkers from the International Fact-Checking Network. Google has worked with partners including the United States Census, the World Bank, and US Bureau of Labor Statistics to populate the repository, which also hosts data from Wikipedia, the National Oceanic and Atmospheric Administration and the Federal Bureau of Investigation. The service expanded during 2019 to include an RDF-style Knowledge Graph populated from a number of largely statistical open datasets. The service was announced to a wider audience in 2019. In 2020 the service improved its coverage of non-US datasets, while also increasing its coverage of bioinformatics and coronavirus.
