Immigration enforcement in Northern California reached a new high this summer, with more immigrants arrested in July than in any other month during the second Trump administration.
Nearly 900 people were arrested in Northern California in July, and some 440 of them were booked into Immigration and Customs Enforcement (ICE) detention, according to a Mission Local analysis of data released this week by the Deportation Data Project.
Compared to other jurisdictions, the number of arrests and book-ins to detention facilities in Northern California is low: Those rates are highest in ICE jurisdictions along the U.S.-Mexico border.
Between May and July, almost half of those arrested in Northern California had no corresponding detention record, suggesting that they weren’t kept in ICE custody.
As of July, in the San Francisco “area of responsibility,” which covers Northern California, Hawaii, Guam and Saipan, there were 20,804 active participants under the “alternatives to detention” program, more than any other jurisdiction in the country.
The data provided by the Deportation Data Project was obtained through a records request to ICE and subsequent litigation.
