As Trump pushes deportations, immigration data becomes harder to find

Immigration Enforcement Data Becomes Elusive Under Trump Administration

The Trump administration’s aggressive promotion of its immigration enforcement agenda through ambitious targets has been accompanied by a troubling decline in the release of reliable, vetted data, breaking with decades of transparent reporting practices.

Unlike previous administrations, Trump’s Department of Homeland Security has significantly reduced the publication of comprehensive immigration statistics, making it increasingly difficult for researchers, advocates, legal professionals, and journalists to track and evaluate the effectiveness and impact of current enforcement policies.

The Office of Homeland Security Statistics, formerly known as the Office of Immigration Statistics, has tracked immigration data since 1872. Under the Biden administration, it began publishing monthly reports that allowed researchers to follow developments almost in real time. However, key enforcement metrics on its website have not been updated since early last year, with a notice indicating the information is “delayed while it is under review.”

“It’s the most timely data. It’s the most reliable data,” explains Austin Kocher, a research professor at Syracuse University who specializes in immigration data trends. “It has the most omniscient view of immigration enforcement across the entire agency.”

The information vacuum extends to other platforms. An interactive dashboard launched by U.S. Immigration and Customs Enforcement (ICE) in December 2023 was initially promoted as a “new era in transparency,” allowing users to examine arrest data, nationalities, criminal histories, and removal numbers. Despite being scheduled for quarterly updates, the latest information available dates back to January 2025, and the agency’s annual report, typically released in December, remained unpublished as of mid-March.

While U.S. Customs and Border Protection continues to publish border encounter statistics and the Department of Justice provides immigration court data, experts note significant slowdowns in other critical areas. The State Department’s most recent visa issuance data is from August, while key statistics from U.S. Citizenship and Immigration Services have not been updated since October.

The data gap comes at a critical moment when the administration has implemented sweeping changes to immigration enforcement. With mass deportations a stated priority, the government has introduced new restrictions and increased enforcement activities, leading to a surge in immigration arrests, detentions, and deportations. Yet the metrics traditionally used to measure these changes are increasingly difficult to find.

Julia Gelatt, associate director of the U.S. Immigration Policy Program at the Migration Policy Institute, expressed concern about the lack of transparency: “We’re all a little bit in the dark about exactly how immigration enforcement is operating at a time when it’s taking new and unprecedented forms.”

When contacted, DHS did not provide specific explanations for the data discontinuation. In a statement, the department claimed, “This is the most transparent Administration in history, we release new data multiple times a week and upon reporter request.”

Instead of comprehensive, verifiable statistics, the administration has released inconsistent figures through press releases and public statements. In January, DHS issued two releases just a day apart with vastly different deportation numbers—675,000 in one announcement and 622,000 in another. Later, in March congressional testimony, Homeland Security Secretary Kristi Noem claimed 700,000 deportations. Yet an Associated Press analysis of ICE’s own data release, mandated by Congress, estimated the number at roughly 400,000 over Trump’s first year in office.

Similarly, DHS has claimed 2.2 million people in the U.S. illegally have “self-deported,” without explaining how this previously untracked metric was calculated.

Researchers and advocates have adapted by relying on congressionally mandated reports or information obtained through legal action. The University of California, Berkeley’s Deportation Data Project successfully sued through the Freedom of Information Act to access data about ICE arrests, including information about nationalities, conviction status, and arrest locations.

Graeme Blair, co-director of the project, noted that while every administration has struggled with transparency in immigration enforcement, the scale of current operations makes verification particularly important. However, even court-mandated data has limitations—information obtained through litigation only covers the period through mid-October, excluding recent high-profile operations like the controversial Minneapolis enforcement surge that resulted in the fatal shooting of two protesters.

The absence of comprehensive immigration data has drawn rare bipartisan criticism. Mike Howell, who heads the conservative Oversight Project, an advocacy group favoring increased deportations, lamented the lack of reliable information: “They aren’t publishing the data,” he said, adding that DHS has instead released numbers in news releases “that purport to be statistics with no statistical backup and the numbers have jumped all over the place.”

Howell added, “We deserve to know the numbers, just like we deserve to know who’s in our country and who needs to leave,” highlighting how the data transparency issue has created unlikely allies across the political spectrum.
