Increased ICE Detention and ATD in First Update of FY 2025

(19 Nov 2024) In the first updated detention numbers since the start of fiscal year 2025, Immigration and Customs Enforcement (ICE) reports holding 38,863 immigrant detainees as of November 2, 2024, an increase of nearly 1,500 individuals compared to the prior release in mid-September. More than half of all detainees are held by facilities located in one of three states: Texas (12,017), Louisiana (6,779), and California (2,957). The largest facility in the country—Adams County Detention Center in Natchez, Mississippi—detains an average daily population of 2,067 individuals.

ICE also reports enrollment in Alternatives to Detention has increased to 181,888. The ICE offices in San Francisco (19,421) and Chicago (19,379) each monitor more than 10 percent of the nationwide ATD enrollee population. SmartLINK, an app that requires users to report presence via smartphone, remains the technology utilized by ICE in over 85 percent of cases. While ICE offices increasingly report using ankle-worn monitors (18,000) and wrist-worn devices (6000) for monitoring ATD enrollees, these together account for only 13 percent of cases.
