Northern California is still where Immigration and Customs Enforcement makes the fewest arrests in the country on a per capita basis, even as federal enforcement has climbed elsewhere. Arrests in 2025 rose in the region, yet the rate per non‑citizen resident remains far below most ICE field offices. For Bay Area readers, that gap reflects a mix of state policy, prosecutorial choices and long‑running community resistance that has changed how federal deportation efforts actually play out on local streets.
Records: What the numbers show
Agency records compiled by the Deportation Data Project show that U.S. Immigration and Customs Enforcement arrested nearly 4,500 people in the San Francisco “area of responsibility” between Jan. 1 and Oct. 15, 2025. Building on those records, a San Francisco Chronicle analysis calculated roughly 217 arrests for every 100,000 non-citizen residents in the region, a figure significantly lower than the national rate.
In ICE jargon, the “San Francisco area” is not just the city by the bay. It covers all of California north of Kern County, plus Hawaii. So the low arrest rate reflects a broad regional pattern rather than some statistical fluke limited to San Francisco proper.
Why California looks different
Researchers and advocates largely point to the state’s legal and political terrain. “California’s sanctuary state law has somewhat dampened ICE’s reach in the state,” Sonja Diaz, founder of the nonprofit Unseen, told the San Francisco Chronicle. She and others argue that the law has redrawn the boundaries of where and how ICE can operate.
Paul Ong of UCLA’s Center for Neighborhood Knowledge added that local politics, decisions by prosecutors and, in parts of the state such as San Diego, simple geography and demographics all help explain the uneven enforcement map. Proximity to the border, different crime patterns and varying levels of local cooperation have created sharply different realities for immigrants depending on where they live in California.
Enforcement tactics have shifted
With many local jails and police departments offering only limited cooperation, ICE has leaned more heavily on community raids, street patrols and courthouse arrests to hit its removal targets. An analysis by the Washington Post documented how these tactics have become more central to the agency’s playbook.
Local reporting by Mission Local and CalMatters has traced what that looks like on the ground, from pre‑dawn home arrests to courthouse pick‑ups that unsettle entire neighborhood events. Residents may see relatively low arrest rates on paper, but advocates say the operations themselves can ripple through schools, workplaces and community gatherings.
Legal background
The California Values Act (SB 54) sets strict limits on how state and local agencies may assist federal immigration enforcement. It spells out narrow exceptions for certain serious crimes and for court‑ordered transfers, and it bars many routine information‑sharing and cooperation practices that once gave ICE easier access to local jails. Readers who want the exact statutory language, including the list of exceptions, can find it on the state’s legislative website.
Local response
Community groups, public defenders and elected officials have pushed back with protests, legal challenges and monitoring projects that track where arrests are happening. Hoodline recently reported on a court action that put a temporary halt on certain courthouse arrests in Northern California, a move that advocates say offered at least a brief reprieve for immigrants who need to appear in court without fearing an immediate handoff to federal agents.
For those who want to dig into the numbers beyond the topline charts, the raw ICE arrest files are publicly posted by the Deportation Data Project. As journalists and researchers continue to comb through that data, the picture that emerges is of a region where sanctuary policy, prosecutorial discretion and organized community resistance have kept ICE’s footprint smaller than in many other parts of the country, even as enforcement strategies continue to shift and adapt.
