Data of, for, and by the people.

This page memorializes the federal datasets and variables, as well as select data tools, that have been terminated or removed in 2025. This list does not include routine changes and terminations of datasets, but rather strives to capture losses to federal data that are extra-ordinary.

Uses federal datasets as the basis for case studies and stories showing how specific datasets support everyday life, policymaking, and the economy.

The American Statistical Association’s project to assess and monitor the health of the federal statistical agencies was launched in 2023 to take the pulse of the nation’s statistical system—the backbone of America’s public data infrastructure. This effort focuses on the 13 federal agencies whose primary mission is to produce official statistics, along with the chief statistician’s office in the U.S. Office of Management and Budget (OMB).

While primarily a tool, CHR&R publicly documents continued availability and archiving of the federal data used in their indicators, emphasizing resilience amid federal data purges.

DataIndex.us is a collaborative effort dedicated to monitoring shifts in federal datasets and identifying emerging risks to public data integrity. The project builds tools that track changes across five key vectors—accessibility, completeness, methodology, continuity, and transparency—to generate actionable risk indicators. These insights help policymakers, advocates, journalists, researchers, and data users understand when and how a dataset’s reliability may be degrading, and where intervention or additional monitoring is needed.

Research collaborative that documents changes to environment-related federal webpages and datasets, and maintains logs of modifications to public environmental information

Public interface for querying many CDC public health datasets with an ad-hoc query system and downloadable outputs.

Coalition effort housed at the Leadership Conference Education Fund that coordinates advocacy, tools, and messaging to support census equity and data disaggregation.

Open-access platform that simplifies U.S. Census and American Community Survey data through searchable profiles, maps, and tables, enabling journalists, advocates, and researchers to quickly explore and contextualize local demographic data without technical barriers.

Geospatial tool originally developed by CEQ to identify “disadvantaged communities” using multiple climate, pollution, and socio-economic indicators; now mirrored by academic/grassroots hosts after federal access was removed.

A comprehensive framework for assessing the health of federal data collections, highlighting key dimensions of risk and presenting a clear status of data well-being.

EPA web app providing 500+ map layers and analysis tools to explore ecosystem services, environmental conditions, and demographics without needing GIS skills.

The 2020 Census conducted a count of residents of the United States and five U.S. territories. It marked the 24th census in U.S. history and the first time that all households were invited to respond to the census online.

The 2026 Census Test is the U.S. Census Bureau's first major opportunity to try out new tools and methods in two locations around the United States. This operational test in support of the 2030 Census will help us improve how we will count everyone in the country in 2030.

Planning for the 2030 Census began in 2019. We are now in the Development and Integration Phase. This phase focuses on ongoing research, testing (including the 2026 Census Test and the 2028 Dress Rehearsal), adjustments based on results of testing, and, lastly, continuing operational planning. This work enables an efficient and accurate count in 2030. The 2030 Census will count residents of the United States and five U.S. territories and will mark the 25th population count in the United States. The data collected by the census is used to determine the number of seats each state has in the U.S. House of Representatives (a process called apportionment) and is also used to adjust or redraw electoral districts based on where populations have increased or decreased. The results also inform decisions about allocating hundreds of billions of dollars in federal funding to communities across the country—for hospitals, fire departments, schools, roads, and other critical programs and services.

The American Community Survey (ACS) is the premier source of detailed information about the nation's people and housing. As an ongoing survey conducted by the U.S. Census Bureau since 2005, the ACS collects detailed social, economic, housing, and demographic information from a sample of households across the 50 states, the District of Columbia, and Puerto Rico. The ACS provides up-to-date information annually, which helps local officials, community leaders, and businesses make informed decisions. Covering more than 40 topics—including education, employment, income, housing, and transportation—the ACS provides crucial insights into the changing needs and conditions of communities. Its data are used for countless reasons, such as to plan roads, schools, and emergency services, and to guide the distribution of government funding.

The AHS is sponsored by the Department of Housing and Urban Development (HUD) and conducted by the U.S. Census Bureau. The survey is the most comprehensive national housing survey in the United States.

The ABS Program combines data results from survey respondents and administrative records to produce data on business ownership. The survey is collected from employer businesses and the nonemployer data are compiled from administrative records.
