We know these things because the federal government collects, organizes and shares the data behind them. Every year, year after year, workers in agencies that many of us have never heard of have been amassing the statistics that undergird decision-making at all levels of government and inform the judgments of business leaders, school administrators and medical providers nationwide.
The survival of that data is now in doubt as a result of the Department of Government Efficiency’s comprehensive assault on the federal bureaucracy.
Reaction to those cuts has focused understandably on the hundreds of thousands of civil servants who have lost their jobs, or are on the verge of doing so, and the harm that millions of people could suffer as a result of the shuttering of aid programs. Overlooked amid the turmoil is the fact that many of DOGE’s cuts have been targeted at a very specific aspect of the federal government: its collection and sharing of data.
In agency after agency, the government is losing its capacity to measure how American society is functioning, making it much harder for elected officials or others to gauge the nature and scale of the problems we are facing and the effectiveness of solutions being deployed against them.
The data collection efforts that have been shut down or are at risk of being curtailed are staggering in their breadth. In some cases, datasets from past years now sit orphaned, their caretakers banished and their future uncertain; in others, past data has vanished for the time being, and it’s unclear if and when it will reappear. Here are just a few examples:
The Department of Health and Human Services, now led by Robert F. Kennedy Jr., laid off the 17-person team in charge of the National Survey on Drug Use and Health, which for more than five decades has tracked trends in substance abuse and mental health disorders. The department’s Administration for Children and Families is weeks behind on the annual update of the Adoption and Foster Care Analysis and Reporting System, the nationwide database of child welfare cases, after layoffs effectively wiped out the team that compiles that information. And the department has placed on leave the team that oversees the Pregnancy Risk Assessment Monitoring System, a collection of survey responses from women before and after giving birth that has become a crucial tool in trying to address the country’s disconcertingly high rate of maternal mortality.
The Centers for Disease Control and Prevention has eviscerated divisions that oversee the WISQARS database on accidental deaths and injuries — everything from fatal shootings to poisonings to car accidents — and the team that maintains AtlasPlus, an interactive tool for tracking HIV and other sexually transmitted diseases.
The Environmental Protection Agency is planning to stop requiring oil refineries, power plants and other industrial facilities to measure and report their greenhouse-gas emissions, as they have done since 2010, making it difficult to know whether any of the policies meant to slow climate change and reduce disaster are effective. The EPA has also taken down EJScreen, a mapping tool on its website that allowed people to see how much industrial pollution occurs in their community and how that compares with other places or previous years.
The Office of Homeland Security Statistics has yet to update its monthly tallies on deportations and other indices of immigration enforcement, making it difficult to judge President Donald Trump’s triumphant claims of a crackdown; the last available numbers are from November 2024, in the final months of President Joe Biden’s tenure. (“While we have submitted reports and data files for clearance, the reporting and data file posting are delayed while they are under the new administration’s review,” Jim Scheye, director of operations and reporting in the statistics unit, told ProPublica.)
And, in a particularly concrete example of ceasing to measure, deep cutbacks at the National Weather Service are forcing it to reduce weather balloon launches, which gather a vast repository of second-by-second data on everything from temperature to humidity to atmospheric pressure in order to improve forecasting.
Looked at one way, the war on measurement has an obvious potential motivation: making it harder for critics to gauge fallout resulting from Trump administration layoffs, deregulation or other shifts in policy. In some cases, the data now being jettisoned is geared around concepts or presumptions that the administration fundamentally rejects: EJScreen, for instance, stands for “environmental justice” — the effort to ensure that communities don’t suffer disproportionately from pollution and other environmental harms. (An EPA spokesperson said the agency is “working to diligently implement President Trump’s executive orders, including the ‘Ending Radical and Wasteful Government DEI Programs and Preferencing.’” The spokesperson added: “The EPA will continue to uphold its mission to protect human health and the environment” in Trump’s second term.) The White House press office did not respond to a request for comment.
Laura Lindberg, a Rutgers public health professor, lamented the threatened pregnancy-risk data at the annual conference of the Population Association of America in Washington last week. In an interview, she said the administration’s cancellation of data collection efforts reminded her of recent actions at the state level, such as Florida’s withdrawal in 2022 from the CDC’s Youth Risk Behavior Survey after the state passed its law discouraging classroom discussion of sexual orientation. (The state’s education secretary said the survey was “inflammatory” and “sexualized.”) Discontinuing the survey made it harder to discern whether the law had adverse mental health effects among Florida teens. “States have taken on policies that would harm people and then are saying, ‘We don’t want to collect data about the impact of the policies,’” Lindbergsaid. “Burying your head in the sand is not going to be a way to keep the country healthy.” (HHS did not respond to a request for comment.)
Making the halt on data gathering more confounding, though, is the fact that, in some areas, the information at risk of being lost has been buttressing some of the administration’s own claims. For instance, Trump and Vice President JD Vance have repeatedly cited, as an argument for tougher border enforcement, the past decade’s surge in fentanyl addiction — a trend that has been definitively captured by the national drug use survey that is now imperiled. That survey’s mental health components have also undergirded research on the threat being posed to the nation’s young people by smartphones and social media, which many conservatives have taken up as a cudgel against Big Tech.
Or take education. The administration and its conservative allies have been able to argue that Democratic-led states kept schools closed too long during the pandemic because there was nationwide data — the National Assessment of Educational Progress, aka the Nation’s Report Card — that showed greater drops in student achievement in districts that stayed closed longer. But now NAEP is likely to be reduced in scope as part of crippling layoffs at the Department of Education’s National Center for Education Statistics, which has been slashed from nearly 100 employees to only three, casting into doubt the future not only of NAEP but also of a wide array of long-running longitudinal evaluations and the department’s detailed tallies of nationwide K-12 and higher education enrollment. The department did not respond to a request for comment but released a statement on Thursday saying the next round of NAEP assessments would still be held next year.
Dan Goldhaber, an education researcher at the University of Washington, cast the self- defeating nature of the administration’s war on educational assessment in blunt terms: “The irony here is that if you look at some of the statements around the Department of Education, it’s, ‘We’ve invested X billion in the department and yet achievement has fallen off a cliff.’ But the only reason we know that is because of the NAEP data collection effort!”
Shelly Burns, a mathematical statistician who worked at NCES for about 35 years before her entire team was laid off in March, made a similar point about falling student achievement. “How does the country know that? They know it because we collected it. And we didn’t spin it. We didn’t say, ‘Biden is president, so let’s make it look good,’” she said. “Their new idea about how to make education great again — how will you know if it worked if you don’t have independent data collection?”
“Reality has a well-known liberal bias,” Stephen Colbert liked to quip, and there have been plenty of liberal commentators who have, over the years, taken that drollery at face value, suggesting that the numbers all point one way in the nation’s political debates. In fact, in plenty of areas, they don’t.
It’s worth noting that Project 2025’s lengthy blueprint for the Trump administration makes no explicit recommendation to undo the government’s data-collection efforts. The blueprint is chock full of references to data-based decision-making, and in some areas, such as immigration enforcement, it urges the next administration to collect and share more data than its predecessors had.
But when an administration is making such a concerted effort to stifle assessments of government and society at large, it is hard not to conclude that it lacks confidence in the efficacy of its current national overhaul. As one dataset after another falls by the wayside, the nation’s policymakers are losing their ability to make evidence-based decisions, and the public is losing the ability to hold them accountable for their results. Even if a future administration seeks to resurrect some of the curtailed efforts, the 2025-29 hiatus will make trends harder to identify and understand.
Who knows if the country will be able to rebuild that measurement capacity in the future. For now, the loss is incalculable.
