What's Happening?
Following the January 2025 inauguration, over 3,000 taxpayer-funded federal data sets from agencies like the CDC, the Justice Department, and the Office of Personnel Management (OPM) were removed or altered online. This action was in response to two White
House executive orders: one directing agencies to remove references to gender ideology and another ending federal diversity, equity, and inclusion (DEI) programs. Researchers observed pages on gender and health at the CDC, the diversity module of OPM’s FedScope database, and a national repository of federal law-enforcement misconduct records at the Department of Justice going offline. In response, a network of volunteers, including graduate students, librarians, and data scientists, launched data rescue efforts. The Preserving Public Health Data Collective at the Harvard T.H. Chan School of Public Health held marathon sessions to mirror accessible data. The Harvard Law School Library Innovation Lab announced a 16-terabyte archive of Data.gov, containing over 311,000 federal datasets harvested across 2024 and 2025, published with digital signatures for provenance verification. The Internet Archive's End of Term crawl and the Data Rescue Project also contributed to preserving data.
Why It's Important?
The removal and alteration of federal data sets have significant implications for public policy, research, and transparency. These datasets cover crucial aspects of American life, from public health and law enforcement to workforce demographics. Their disappearance or modification creates gaps in longitudinal data, making it challenging for researchers to track trends, evaluate policies, and understand societal changes over time. For instance, the removal of gender identity questions from the CDC's National Notifiable Diseases Surveillance System and the Bureau of Justice Statistics' National Crime Victimization Survey will hinder the ability to assess health disparities and victimization rates among specific populations. The decommissioning of the National Law Enforcement Accountability Database eliminates a centralized source for federal law enforcement misconduct records, impacting hiring processes and accountability. The lack of proper documentation for changes, as highlighted by The Lancet audit, undermines data integrity and public trust. This situation affects not only academic researchers but also policymakers who rely on accurate and comprehensive data to make informed decisions, potentially leading to less effective or equitable policies.
What's Next?
The immediate future will likely involve continued efforts by academic institutions and non-profit organizations to preserve and make accessible the federal data that has been removed or altered. However, these rescued copies come with limitations regarding provenance and chain of custody, which can complicate their use in formal research and policy discussions. The absence of certain data points, such as gender identity in future surveys, means that these gaps cannot be retroactively filled, creating permanent discontinuities in longitudinal studies. The non-profit Climate Central has already revived NOAA's Billion-Dollar Weather and Climate Disasters database, indicating a potential trend of non-governmental entities stepping in to maintain critical public data. The long-term impact will be felt by researchers and policymakers who will encounter data gaps timestamped to early 2025, affecting their ability to analyze trends in public health, social equity, and law enforcement. This situation may also prompt further discussions about data stewardship, government transparency, and the role of independent archives in preserving public information.
Beyond the Headlines
The systematic removal and alteration of federal data sets raise profound questions about the nature of public information and government accountability. The executive orders targeting gender ideology and DEI programs, and their subsequent impact on data, suggest a deliberate effort to reshape narratives and policy priorities by controlling access to information. This goes beyond mere administrative changes; it represents a challenge to the principle of evidence-based policymaking and the public's right to access data collected with taxpayer money. The fact that a federal judge had to order the restoration of some health websites, which then returned with disclaimers stating they 'do not reflect biological reality,' highlights a concerning trend of political commentary being appended to scientific data. This situation underscores the vulnerability of public data to political shifts and the critical role of independent organizations in safeguarding information for future generations. It also brings to light the ethical implications of altering historical data without transparent change logs, potentially distorting public understanding and historical records.
