data statistics finding removed government datasets

Since a flurry of executive orders were issued in early 2025, thousands of datasets and webpages have been removed from federal government websites. The removals have focused on content relating to both topics that have been the subject of executive orders (e.g. gender, structural inequality, climate science, and public health) and content on other topics that uses vocabulary common to research on the topics targeted by the orders. This guide provides a workflow for researchers needing access to data that has been removed. Most US federal government datasets are still available on data.gov, if you have not heard specific reports that a dataset has been removed or moved, begin searching by name or topic on data.gov. If the data is not indexed on Data.gov and you know which government agency produced the information, check their website directly.

The Internet Archive's Wayback Machine indexes many (but not all) .gov webpages. It works best if you have the exact url for the old page - you may be able to find this from cached google search results, citations, etc. A new presidential administration typically brings significant changes to federal government websites. What is not typical, however, is the pressure faced by executive agencies in the second Trump administration to remove data and take down websites that conflict with the president's political views as outlined in... It has become increasingly common for government data sets that were previously publicly available to be removed. Some of these datasets may be altered and made available again, while others may remain offline indefinitely.

Below is a list of non-governmental resources that have some US government-produced data. Please feel free to contact me if you need any help finding US government information. Have a question we haven't answered yet? Starting in the early months of 2025, access to a variety of federally-created and/or federally-hosted datasets has been limited or removed due to various Presidential Executive Orders. Researchers from a variety of disciplines use this data, and continued access is key to their work. Librarians, among others, have worked to gather, organize, and share where these datasets have been archived or are currently hosted.

This page serves as a resource for some of this information but is by no means complete. If you have questions about locating a particular dataset, or finding data on a topic, either federal or not, please reach out to us at librarydataservices@umass.edu. The Data Rescue project is a collaboration between several data organizations, many of which are also library-adjacent. They include IASSIST, RDAP, and members of the Data Curation Network. They maintain the Data Rescue Tracker, which tracks specific datasets that we taken down from public sites, and where it is hosted currently. It also shows sets that are yet to be archived but which are in progress.

This LibGuide is a living document that is continually being edited and improved. Much of the original content was derived from a Google document titled “Data Rescue Efforts,” which circulated in February 2020. The collaborative group behind that document has since grown into the Data Rescue Project. We gratefully acknowledge their foundational work and the ongoing, collective efforts of the data preservation community. Below is a concise guide to help you locate US federal government data that may have been removed or redacted following the Presidential Executive Orders that went into effect on January 31, 2025. Please note that this guide only covers how to find removed information.

For current or active government data, you should use Data.gov, which remains the best resource for discovering existing federal data. Before you begin searching for rescued data, it's a good idea to double-check that the information is truly gone from official sources: If you have confirmed that the data or information is missing, move on to archival resources. The Internet Archive Wayback Machine is the largest web archive, capturing snapshots of websites across the internet over time. It allows you to view websites as they appeared on specific dates in the past. Beginning in January 2025, many federal datasets, websites, and other previously accessible resources, across agencies, are being taken offline to comply with executive orders.

In some cases, press releases or data documentation have been removed; in others, entire datasets have been taken down. Evidence is growing that even datasets that remain accessible on an agency’s website may have scrubbed, corrupted, or otherwise altered information.

Following executive orders from President Donald Trump's administration, government organizations removed or modified over 8,000 web pages and approximately 3,000 datasets. The changes primarily affected content related to diversity, equity, and inclusion (DEI) initiatives, gender identity, public health research, environmental policy, and various social programs, and other topics Trump and the Republican Party has expressed... Major affected agencies included the Centers for Disease Control and Prevention, which saw over 3,000 pages altered or removed, and the Census Bureau, which removed about 3,000 pages of research materials.

While some content was later restored, the modifications represented significant changes to federal government data accessibility and sparked legal challenges from healthcare advocacy groups. Agencies of the United States government share open data for many uses. There are many civic technology, research, and business applications which rely on access to government data.[1] Dataset deletion can be useful maintenance or the result of poor archiving practice.[2] There is little government regulation... In 2009, Data.gov was established to improve public access to high value, machine-readable datasets generated by the Executive Branch of the Federal Government.[5] In 2019, the OPEN Government Data Act ordered agencies to share... Various federal agencies release data on their own websites. In 2019, Trump signed into law the Foundation for Evidence-Based Policymaking Act, which established a system for utilizing data to construct evidence-based policy.

Trump's second administration showed a dramatic pivot from this law passed during his first administration.[6] In late January 2025, organizations under the Department of Health and Human Services (HHS) paused their external communication during a review.[7] This guide 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. Many of the resources linked here have been identified by the Data Rescue Project and LibGuides from other colleges and universities.

Recent executive orders and federal agency actions have raised questions about the future of publicly available government data, what can and can’t be published, and how the future of government-funded research will play out. So far, this has impacted some federal health data, USDA climate change information, Federal Depository Library Program (FDLP) libraries, and more. This guide provides access to and information about United States government data and webpages that have been removed since January 2025. It is divided into Environmental Data, Health and Medical Data, Other Data, and Government Websites. A list of groups working to rescue government data is also available.These resources are intended for research purposes and will be updated as new information is available. If you are have data resources to share, please contact your subject librarian.

When searching for government data that may have been removed, search in this order: Not sure what dataset you need? Here are some search tips. Your subject librarian can also help you with this. For help evaluating data quality, the Data Quality Literacy Guidebook is a good place to start. As you search for information, save your sources, particularly datasets and government publications.

Note the date you were last able to access a source in case it isn’t available later. Check the Internet Archive’s Wayback Machine and other repositories for removed data sources or websites.
