Archived Federal Data (2025)

This page has been created in response to recent and ongoing removal of federal datasets, websites, and other digital resources. It is a work in progress and will be updated as new archives and repositories are surfaced. Please reach out to us if you need assistance in locating data or if you know of a resource that you think should be included. Many of the resources linked here have been gathered through the efforts of the Data Rescue Project (https://bsky.app/profile/datarescueproject.org). 

While many of the sources below are easy to search and use, some -- especially the mirrored datasets -- will be more complicated to access. Please reach out to us if you run into any issues.

DataLumos accepts deposits of public data resources from the community and recommendations of public data resources that ICPSR itself might add to DataLumos.”

Harvard's Library Innovation Lab Team's Data.gov Archive

“The 16TB collection includes over 311,000 datasets harvested during 2024 and 2025, a complete archive of federal public datasets linked by data.gov. It will be updated daily as new datasets are added to data.gov.”

Harvard's Climate Change and Health Research Coordinating Center (CAFE) Collection

Harvard Dataverse deposits including data from a number of federal agencies. “The purpose of this sub-collection is to store critical climate and health datasets accessible at various locations in one place. Because these datasets are extracted with minimal modification, complete metadata that notes where appropriate citation data can be found is especially important to note.”

IPUMS

Access to U.S. survey products, including ACS, Current Population Survey microdata and Decennial Census data. "IPUMS provides census and survey data from around the world integrated across time and space. IPUMS integration and documentation makes it easy to study change, conduct comparative research, merge information across data types, and analyze individuals within family and community contexts. Data and services available free of charge."

Government Website Archiving

The End of Term (EOT) Web Archive

“The End of Term Web Archive captures and saves U.S. Government websites at the end of presidential administrations. The EOT has thus far preserved websites from administration changes in 2008, 2012, 2016, and 2020. We are currently accepting URL nominations for the End of Term 2024 Web Archive.”

GovDiff

Tool created by Jerome Paulos to show side-by-side changes in government websites, using the Internet Archive’s crawls.

The Internet Archive's Wayback Machine

“Explore more than 916 billion web pages saved over time”

Archived White House website of the Biden Administration

From the Joseph R. Biden Jr. Presidential Library: “The official files that make up a Presidential administration's website are preserved in the National Archives’ Executive Office of the President Electronic Records Archive. In order for the public to easily access the websites, the National Archives has taken an additional step to "freeze" the websites and make them available online. Because the archived websites are hosted by the National Archives and are historical material, they are no longer updated. Any broken links (internal or external) will not be updated.”
