Experts warn that the lack of transparent, verifiable data hampers accountability and analysis of immigration policies even as enforcement actions intensify, with DHS and ICE releases showing inconsistencies in deportation totals across different reports and testimony.

Other data sources, such as CBP border encounter statistics and DOJ immigration court data, continue to be published to some extent, but overall data availability has slowed.

There is bipartisan criticism of data omissions, with calls for timely and accurate statistics to enable proper oversight and public understanding.

ICE detention statistics, normally released biweekly and required by Congress, have faced delays and data revisions that hinder analysis.

Key enforcement metrics from the Office of Homeland Security Statistics have not been updated since early last year, with a note that the page is delayed while under review, reducing public access to critical data.

FOIA and legal actions, such as UC Berkeley’s Deportation Data Project, have partially salvaged data access by obtaining ICE arrest data, though datasets cover mainly pre-October periods and may not reflect recent operations.

Researchers have relied on litigation and alternative datasets to fill gaps, but access remains limited in scope and recency and does not fully reflect current enforcement activity.

Independent efforts, including UC Berkeley’s Deportation Data Project, have used FOIA to obtain data, but these datasets have limitations in both scope and timeliness.

The data gaps intersect with broader policy debates about transparency, governance, and the scope of immigration enforcement under the Trump administration, including contested figures on total removals and where arrests occur.

While some agencies continue to publish statistics, crucial metrics—monthly reports, annual totals, deportation counts—are missing or inconsistently reported, complicating comparisons as of mid-March 2026.

Overall, several agencies publish partial data (CBP border encounters, DOJ immigration court data), but many critical figures remain incomplete or missing at this time.
