Washington DC-Immigration and Customs Enforcement (ICE) now monitors nearly 185,000 people under its Alternatives to Detention (ATD) program, the highest number since February 2024 but still below the total monitored at this time last year. Enrollment trends vary by ICE’s regional offices. Chicago’s office monitors over 19,000 people under ATD, 4,600 more people than the office did in December 2023. Other offices that have assigned more people to the program include the Los Angeles office (increase of 3,700), New York (3,100), and Seattle (2,800). By contrast, Harlingen and San Antonio ICE offices have cut their ATD monitoring activity in half over the last 12 months, monitoring 9,000 and 7,900 fewer individuals in each of their respective regional offices.
The recent update reported a total of 38,728 people in ICE custody, an increase of about 2,000 people compared to early December 2023. The data also suggests a continuation of shifting arresting authority numbers between ICE and Customs and Border Protection (CBP). ICE arrested 36 percent of current detainees compared to CBP’s 64 percent. At this time last year, ICE was reported as the arresting authority behind 28 percent of people held in ICE detention facilities, whereas CBP had arrested 72 percent of individuals.
