A Shortlist of Federal Data the Trump Administration Has Tampered With or Destroyed in Acts of Greater Transparency

The breadth of federal data and statistics erased or altered under President Donald Trump’s administration is so vast that no definitive list can fully capture it. When Trump signed executive orders this January and February to eliminate diversity, equity and inclusion (DEI) programs, federal agencies raced to comply. According to contemporaneous estimates, the agencies removed or modified about 8,000 webpages and roughly 3,000 datasets. Some content was later reinstated, but often with changes whose full scope remains uncertain even months later.

Margaret Levenstein, director at the University of Michigan’s Inter‑university Consortium for Political and Social Research, cautions that while some changes clearly targeted identity‑related content, many revisions lack transparency. “We don’t know what else might have been changed,” she says.

Among the most affected areas were datasets dealing with transgender and gender identity, race, and diversity—particularly impacted by Trump’s “Defending Women” and “Ending Radical and Wasteful Government DEI Programs” orders. These stand out as explicit examples of how policy choices have weakened the reliability and availability of data that matters for public life.

The damage goes deeper than just removed files: the administration also purged expert staffing across statistical agencies. Major policy and research bodies—like the National Center for Education Statistics, USAID, and the National Occupational Research Agenda—faced layoffs or leadership changes. The dismissal of experienced officials, including the former Bureau of Labor Statistics commissioner, exacerbated what was already a fragile data infrastructure.

Many agencies had long cited budget constraints as a barrier to maintaining timely and accurate data. But under this administration, those struggles have become far more acute. Levenstein argues the solution lies in providing agencies with stable funding, independence, and a renewed commitment to data integrity.

Dana Willbanks from the Climate Science Legal Defense Fund adds a note of caution: “Anything from the federal government now has to be treated with skepticism,” she says, “depending on who’s issuing it.”

The White House insists it continues to publish “timely, reliable, and accurate” data, but excludes from that commitment any programs tied to DEI or “ideological agendas.”

In practice, however, transparency has suffered dramatically. Below is a sample—by no means exhaustive—of key datasets, programs, and information that have been compromised:

Examples of Compromised Data

Health & Family

• The CDC’s Pregnancy Risk Assessment Monitoring System (PRAMS)—a critical survey tracking maternal health indicators—was slated for elimination.

• A federal court ruling intended to shield some health agency workers from layoffs allowed others to proceed, including staff handling data on violence and child abuse.

HIV/AIDS

• Data from PEPFAR, the U.S. global HIV/AIDS program, was taken offline. Its program data page now lists multiple releases only as “TBD.”

• The HHS “Living with HIV” page now carries disclaimers rejecting “gender ideology,” raising questions about whether the content was reworked.

COVID-19

• On archived versions, the CDC recommended COVID vaccination during pregnancy—but the current version lacks that guidance.

• In August, the CDC adjusted its recommendations, advising individuals to consult a professional before getting vaccinated amid safety concerns.

Public Benefits & Social Indicators

• The administration canceled the USDA survey on food insecurity just before cuts to SNAP. With no annual measure, worsening hunger may go unrecorded.

• The Census Bureau’s QuickFacts portal, long a key resource for demographic snapshots, has been offline since at least August, with no clear plan for restoration.

Climate & Environment

• USDA removed climate‑related landing pages, ostensibly for “review” and only partially restored them, sometimes with disclaimers.

• A memo revealed that terms like “safe drinking water,” “indigenous,” and “black” were banned from certain publications.

• The multi‑agency U.S. Global Change Research Program went offline in June; NASA declined to host its data, citing no legal obligation.

• The EPA halted updates to its widely used greenhouse gas emissions calculator after the scientist who maintained it criticized the president.

• The Atlas 15 climate project, designed to forecast extreme rainfall events, was suspended—later resumed only after press coverage of fatal floods.

Workforce & Government

• The FedScope Database, which tracks federal workforce demographics, removed race and ethnicity modules and is revising its approach to gender.

• The National Institute for Occupational Safety and Health saw its role pared back, weakening research underpinning workplace safety.

• A database tracking federal police misconduct, created during the prior administration, was dismantled under a Trump order.

Economics & Oversight

• Trump disbanded two expert panels (including one advising on inflation and GDP) whose oversight helped maintain the quality of economic statistics. 

• The removal of advisory experts across multiple agencies—including labor, commerce, and census units—has drawn concern that economic data will become less reliable.

• Legal moves also targeted health, FDA, and other agencies for removing clinical and survey data, prompting lawsuits. 

• Environmental and advocacy groups have sued over the deletion of climate and environmental justice resources, calling it tantamount to theft. 

• A judge ordered agencies to reinstate certain health webpages and datasets, acknowledging that removal harmed public health interests. 

Though many resources have been restored in name—Data.gov, for instance, now lists over 311,000 datasets—questions remain about how many were altered, how many remain inaccessible, and how much similar censorship continues behind the scenes. 

In short, the Trump administration’s actions mark a fundamental reshaping of how the federal government handles transparency, data, and accountability. The long-term effects on research, policy, trust, and governance are still unfolding.
