The Deportation Data Project collects and posts public, anonymized U.S. government immigration enforcement datasets. We expect these datasets to be used by journalists, researchers, lawyers, and policymakers.

Yes, as far as we understand, ICE does not collect statistics on US citizens who are arrested or detained. They do not appear in the data released to us.

We link to the raw data (obtained from ICE and posted in December 2025) and the code we used to analyze along with the report.

Maybe because of the lower release rate, voluntary departures (which are rare compared to removals) have increased by 21 times.

The rate of deportation within two months of initial detention is up by about a quarter, from 55% to 69%, and the declining release rate accounts for most of that increase.

Second, once arrested, few were released. Release within 60 days of arrest, already rare in the last six months of the Biden administration (16%), now almost never happens (3%). This is because of changes to policies at ICE and the immigration courts.

First, the administration roughly tripled the number of detention beds used for people arrested within the United States. That capacity increase was a result both of new funding and, less well understood, of a decrease in arrests at the border.

The quadrupling (4x) of arrests resulted in a 4.6x rise in deportations because of increased detention space, decreased releases, and an increase in immigrants accepting voluntary departure. We’ll break down each one.

ICE street arrests (i.e. arrests not at jails) went up by over a factor of eleven by the last month of our data up through Oct. 15, 2025, compared to the last six months of Biden admin. Street arrests at this order of magnitude are a new phenomenon.
