Together, the administration's detention apparatus is forcing noncitizens into a difficult choice, stay in detention and likely be removed, or give up their case. Many are choosing to give up. So-called voluntary departures are up **28x** under the new administration.
Plot of voluntary departures by week from July 2024 to January 2026 showing exponential growth in 2025 leveling off at a high rate of over ~2500 per week in early 2026.

The other big reason is that border arrests are way down, a trend that began under Biden and continued under the new Trump administration. Tens of thousands of beds were made available because of this.
Plot of divergent trends in border arrests (down significantly in end of Biden administration and continuing through Trump administration and arrests inside the US which go up 4.4x over this period.

The second reason is the greatly expanded availability of detention beds for arrests inside the US. These come from the large facilities built by the new administration like Alligator Alcatraz, but while those are a growing % most are elsewhere in existing facilities, some w/ expanded contracts.
Plot of total overnight detainees over time for newly-built facilities like Alligator Alcatraz which go up in 2025 starting in July but still represent a small proportion compared to all other facilities, which go up more and faster.

Street arrests happen both in highly visible ways -- in the raids in LA, DC, Chicago, and Minneapolis But we show that is a small % of total street arrests — just 15% at the height of the MN surge. They are happening across the country at ICE check-ins, in immigration court, and in neighborhoods.
City-by-city arrest counts by week for LA, DC, Chicago, and Minneapolis illustrate the largescale immigration raids in those cities beginning June 2025 and continuing through January 2026.

One reason deportations skyrocketed was the well-known pattern of "street arrests", which we show increase increased by *11x* since the last half of the Biden admin But custodial transfers from jails or prisons also went up, doubling over the first year of the new administration
Plot of custodial arrests and street arrests over time by week from July 2024 to January 2026 showing marked increase especially of street arrests.

Today we posted a new, simplified version of the EOIR immigration courts dataset for removal cases - which we'll update each month. EOIR tracks every decision on the merits of an immigration case & bond outcomes, applications for relief, immigration charges, appeals, and detention. More 👇

NEW! We posted a processed dataset to our website that allows users to view daily counts of the number of people detained at each detention facility holding individuals in ICE custody from September 1, 2023, to October 15, 2025.

Maybe because of the lower release rate, voluntary departures (which are rare compared to removals) have increased by 21 times.
Rate of voluntary departures increased from low at end of Biden administration by 21x in last month of data in Trump administration.

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.
Rate of release within 60 days drastically declined (16% at end of Biden admin. to 3% in last month of the data), and rate of removal (deportation) increased.

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.
Detentions from border arrests declined, starting at end of Biden administration, opening detention beds for arrests in the interior of the US.

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.
ICE street arrests went up by 11x. Both street arrests and custodial arrests (transfers from jails and prisons) increased from the end of the Biden administration.

👋 Joining BlueSky to launch our first report, on immigration enforcement in the first nine mos. of the Trump admin. Big picture: deportations from interior arrests are up 4.6x from the end of Biden's term, from big increase in arrests, expansion in detention beds, & drastic reduction in releases.
4.6x increase in weekly removal rate from end of Biden administration to last month of data in Oct. 2025
