The National Center for Science and Engineering Statistics (NCSES) is the principal federal agency for producing data on science, technology, engineering, and mathematics (STEM) activities in the United States. Operating within the U.S. National Science Foundation, NCSES collects and reports official statistics on research and development (R&D) expenditures, the STEM workforce, innovation indicators, research institutions, and related trends across the public and private sectors.

The NCSES website provides access to interactive data tools, downloadable datasets, analytical reports, and methodological documentation. Its data support research, policy analysis, and planning on topics such as national competitiveness, research capacity, workforce development, and technological change, and are widely used by policymakers, academic researchers, and industry analysts.

NCSES Data Tools is the National Center for Science and Engineering Statistics’ suite of interactive interfaces for accessing science and technology statistics. It provides search, visualization, and download options for data on research and development, STEM employment, innovation, and related indicators. These tools support analysis and exploration of U.S. science and engineering trends for research, policy, and planning.

The Statistics of Income (SOI) program is managed by the Internal Revenue Service (IRS) and produces official statistical information derived from tax returns filed by individuals and businesses in the United States. SOI publishes detailed data on income, deductions, tax liabilities, credits, and distributions across income groups, industries, and geographic areas. Its products cover topics such as individual and corporate income tax statistics, estate and gift tax data, and patterns of income reporting.

The SOI portal provides access to tables, historical series, publications, and electronic datasets that are used by researchers, economists, policymakers, and analysts for economic and fiscal analysis, tax policy evaluation, distributional studies, and revenue forecasting. Because SOI statistics reflect actual tax filings, they are a key source for understanding income distribution and the tax system’s impact on economic and social outcomes.

The NASS website provides access to survey results, interactive data tools, downloadable datasets, publications, and methodological documentation. Its statistics are widely used by farmers, researchers, policymakers, and market analysts to monitor agricultural trends, inform decision-making, and support economic analysis and planning in the agricultural sector.

U.S. EIA Data Tools, Apps, and Maps is a collection of interactive tools provided by the U.S. Energy Information Administration for exploring energy statistics. It includes customizable data interfaces, visualization apps, and maps covering energy production, consumption, prices, emissions, and infrastructure. These tools help users analyze trends, compare energy indicators, and support research and policy analysis.

USDA Economic Research Service Data Products is the data portal of the Economic Research Service providing access to economic and statistical datasets on agriculture, food systems, and rural conditions. It includes interactive charts, downloadable tables, and series on farm income, commodity markets, food prices, nutrition assistance participation, and rural demographics.

The U.S. Bureau of Economic Analysis (BEA) is a principal federal statistical agency within the Department of Commerce responsible for producing the nation’s official economic accounts. BEA publishes key indicators such as Gross Domestic Product (GDP), personal income, corporate profits, international trade and investment statistics, and regional economic data for states, metropolitan areas, and counties.

Through its website, BEA provides access to data tables, interactive tools, downloadable datasets, and methodological documentation. Its statistics serve as the benchmark measures of U.S. economic performance and are widely used by policymakers, researchers, businesses, and journalists to analyze economic trends, assess policy impacts, and guide decision-making at national and regional levels.

BEA's interactive data application is the one stop shop for accessing BEA data on the fly. The interactive application makes it easier to access and use our statistics by providing a common look and feel for users accessing national, international, regional or industry statistics. The application makes the data easier to print, save and export. The charting features are robust and visually appealing. The application also allows for data sharing with others via a number of social tools.

BEA updates its data in near real time. During BEA news releases there might be a slight delay in accessing the most recent data but access to supplemental data files is always available.

The interactive data application organizes data by account and topic. The application uses a "tabbed" browser experience common to many e-commerce and other standard Web sites. Navigating between data sets and accessing and changing query parameters is easy, as they are similar across all datasets.
