Disappearing Federal Data: Implications for Addressing Health Disparities
Introduction
Data are a cornerstone for efforts to improve health and health care, including addressing disparities. Federal data can act as “essential infrastructure,” with policymakers and institutions relying on demographic, geographic, and health outcomes data, among others, to make important decisions around resource allocation. Data are important for identifying health status and needs, including disparities; directing efforts and resources to address needs and disparities as they are identified; assessing the impacts of policy changes; and establishing accountability. Without adequate data, health needs and disparities may remain unseen and unaddressed. Further, lack of reliable and transparent data can erode public trust in government institutions, negatively impact willingness to participate in future federal data collection efforts, and make policy implementation challenging.
The Trump administration has taken actions to eliminate equity-related initiatives and has removed federal data from online sites, deleting sociodemographic variables from datasets, and has delayed the release of some data. This policy watch reviews recent changes in availability and timeliness of federal data based on a review of publicly available federal datasets that are commonly used to measure health and health care as of August 2025. The identified changes, which largely include removal of data or variables relating to race or ethnicity or sexual orientation and gender identity (SOGI), may not be exhaustive as they focus on a subset of federal datasets and since several datasets are being modified on an ongoing basis. Looking ahead, there are likely to be continued declines in the availability and timeliness of federal data. While most changes have affected racial or ethnic or SOGI data to date, other domains could be affected in the future.
Decreased availability of federal data may impede efforts to identify and address health needs and disparities, trend changes in health and health care among different groups over time, and impact how resources are allocated, which could lead to overall declines in the nation’s health and productivity.
Recent Federal Actions on Data Availability and Research
The Biden administration took several steps to increase the availability of disaggregated federal data to advance health equity. For example, in March 2024, the Office of Management and Budget (OMB) announced revisions to Standards for Maintaining, Collecting, and Presenting Federal Data on Race and Ethnicity, which apply to federal data collection and reporting. These revisions were the first ones issued since 1997. The OMB indicated that they were intended to result in more accurate and useful race and ethnicity data across the federal government and to better represent the increasing diversity of the U.S. population. The administration also issued several Executive Orders and Equity Action Plans aimed at “advancing equity and racial justice” which included “building accountability for equity through data collection and reporting” by federal agencies. The Biden administration also prioritized equity and enhanced data collection for Lesbian, Gay, Bisexual, Transgender, Queer, and Intersex (LGBTQ) people through its Executive Orders.
In contrast, the Trump administration has taken actions to eliminate equity-related initiatives, including eliminating policies, initiatives, and research focused on specific populations, including people of color and transgender or gender non-conforming people. On the first day of his second term, President Trump signed Executive Order 14148 which revoked 78 executive orders and memoranda issued by the Biden administration, many related to diversity, equity, and inclusion (DEI) and LGBTQ equity and data collection. Additionally, Executive Order 14168 impacted data collection, data presentation, and distribution related to transgender people as it directs the “removal of all statements, policies, regulations, forms, communications, or other internal and external messages that promote or otherwise inculcate gender ideology, and shall cease issuing such statements, policies, regulations, forms, communications or other messages.” President Trump also issued Executive Order 14151 and directives that mandate federal agencies to terminate all DEI related offices and positions; equity action plans, actions, initiatives or programs; equity-related grants or contracts; and DEI performance requirements for employees, contractors, or grantees. To carry out the Executive Orders, the Office of Personnel Management (OPM) directed agencies and departments to take down all outward facing media that “inculcate or promote” “gender ideology,” as well as to remove all public facing DEI related websites and content, though due to court order, at least some of this appears to have been restored.
The Trump administration also restructured and made major reductions in staffing that may limit resources available to support data collection and reporting. On March 27, 2025, the Trump administration announced a restructuring of the U.S. Department of Health and Human Services (HHS) that led to a large “Reduction in Force” among federal staff, including cutbacks to programs and staff working on data collection, research, and enforcement.
The Trump administration also made significant funding cuts to research on health disparities, cancer, and climate change, among others, which may reduce data available to understand health and drivers of disease as well as effective interventions. In February 2025, the administration announced billions of dollars in funding cuts for medical research at hospitals and universities. The administration also announced the cancellation of National Institute of Health (NIH) grants for health disparities research, as part of larger NIH grant cuts totaling over $1 billion as of July 2025. Further, funding and staff cuts at the National Cancer Institute (NCI) could impact cancer research. The administration has also canceled over 100 climate change-related research projects at the National Science Foundation (NSF). Further, in their budget request to Congress, the administration has requested additional cuts to NIH.
Recent Changes in Availability of Federal Data
During the early days of the second Trump administration, federal agencies removed thousands of publicly available datasets and/or public health webpages, although they were largely returned following legal challenges. These removals included data from the U.S. Census Bureau, the Environment Protection Agency (EPA), and the Centers for Disease Control and Prevention (CDC), among others. Following legal challenges, much of the data have since been restored; however, there have been some changes made to variables and information, particularly data on gender identity, and in some cases sexual orientation. Many federal websites include messages indicating that data are being updated to comply with Trump administration priorities and also to comply with ongoing legal challenges (Box 1).
Box 1: Example of Message on Federal Websites Indicating Data Changes
“Per a court order, HHS is required to restore this website to its version as of 12:00 AM on January 29, 2025. Information on this page may be modified and/or removed in the future subject to the terms of the court’s order and implemented consistent with applicable law. Any information on this page promoting gender ideology is extremely inaccurate and disconnected from truth. The Trump Administration rejects gender ideology due to the harms and divisiveness it causes. This page does not reflect reality and therefore the Administration and this Department reject it.”

KFF review of major federal health datasets as of August 2025 shows that certain sociodemographic variables have been removed from some datasets or reports, including racial and ethnic and gender identity data. Some examples of removals or changes to racial and ethnic data include:
- Detailed racial and ethnic data broken out by other factors such as an individual’s age and/or sex collected by the CDC’s National Center for Health Statistics (NCHS) Data Query System (DQS) had been removed for a number of health indicators including but not limited to infant, neonatal, and post-neonatal mortality rates; recent substance use among youth; and heart disease death rates.
- Racial and ethnic data also were omitted from the 2024 annual report for the National Survey on Drug Use and Health (NSDUH), despite being included in earlier annual reports as well as being a focus of prior companion reports.
- The diversity module containing federal workforce data broken out by race and ethnicity was removed from the most recent version of the quarterly workforce report from the OPM. In addition, the OPM has not updated its quarterly workforce data since September 2024.
Examples of changes to or removals of SOGI data include:
- Several federal datasets such as the CDC’s heart disease mortality data and the Behavioral Risk Factor Surveillance System (BRFSS), among others, were briefly taken down and then republished after renaming the “gender” variable to “sex”.
- Questions related to gender and gender identity have also been removed from recent BRFSS data, including questions about respondents’ sex at birth and whether they identify as transgender.
- The Trump administration stopped collecting gender identity data through the Medicare Current Beneficiary Survey, which had begun collecting these data in 2023.
- The Health Resources and Services Administration’s (HRSA) Uniform Data System (UDS) also removed data elements related to SOGI going back to 2016 when the UDS first started including SOGI questions. UDS is used to report program data for community health centers funded by HRSA which are disproportionately more likely to serve patients from historically marginalized and disadvantaged communities.
Availability of federal data to measure health and health care may become more limited moving forward due to staffing and other changes. For example, the future of the Pregnancy Risk Assessment Monitoring System dataset, considered a “gold standard” for understanding maternal and infant health and related disparities, is uncertain given the HHS staff cuts impacted the entire team overseeing it. Further, President Trump recently fired the Commissioner of the U.S. Bureau of Labor Statistics (BLS). Several economists have called into question the objectivity of future BLS data following the appointment of a new Commissioner from a conservative think tank. In September 2025, the Agriculture Department announced that it will cancel future surveys measuring food insecurity in U.S. households, which has been measured since the 1980s. Additionally, President Trump recently suggested excluding undocumented immigrants from the 2030 Census, which would no doubt be challenged as unconstitutional and conflicts with longstanding standards for conducting population tallies using the Census dating back to 1790. An informational copy of the 2025 American Community Survey published by the U.S. Census Bureau does not reflect the most recent OMB updates to racial and ethnic data collection. It still includes separate questions to ascertain Hispanic origin and race as opposed to a single combined question and also does not include a Middle Eastern or North African (MENA) category. Given the Trump administration’s actions on SOGI research thus far, there also may be reductions in the availability of SOGI data moving forward.
