Number of Immigrant Detainees Arrested by ICE Continues to Increase
(26 Apr 2024) The number of immigrants in ICE detention who were arrested by Immigration and Customs Enforcement (typically representing 'interior enforcement') instead of Customs and Border Protection (typically at or near the US borders) has grown steadily to now over 12,000 for the first time since November 2020. In that month, similar data released by ICE reported 11,503 detainees at that time were arrested by ICE.

According to the latest data released by Immigration and Customs Enforcement (ICE), out of the 34,373 detainees held in detention, 12,083 (or 35%) were arrested by ICE. The rise in total number of ICE-arrested detainees comes even as the overall numbers of detainees nationally has fallen slightly from two weeks ago to 34,373, driven by fewer numbers of CBP arrests that result in detention.

The number of migrants who are electronically monitored by ICE's alternatives to detention (ATD) program remains remarkably steady and currently totals 184,318. Notably, however, the agency's use GPS smartwatches continues to increase, and now reaches a total of 1,441—up from under 1,000 two weeks ago. GPS ankle monitors, which had declined to under 5,000 in June 2023, also continues to increase and now stands at over 20,000 for the first time since May 2022.

Among all of ICE's areas of responsibility (AORs), the number of migrants monitored on ATD in El Paso has jumped most significantly since the end of last fiscal year. While many AORs—such as Miami, San Antonio, and Washington, D.C.—are monitoring fewer migrants than before, the El Paso AOR increased from a total of 2,935 migrants at end of September 2023 to 7,644 in the most recent data. This is much lower than the AOR's with most immigrants monitoring, including San Francisco at 18,630 and Chicago at 17,215, but represents a significant relative increase.

Note TRAC's previous reports that raise concerns about the quality of ICE's public ATD data, specifically related to the accuracy of data on the number of migrants on GPS ankle monitors.
