Counties in California
58 counties on record with at least one law enforcement agency in California.
No county-level crime rate or population figure appears here. A sheriff’s office and the city police departments inside its county serve overlapping populations, so summing officers or residents across a county double-counts people covered by more than one agency. These pages list agencies only.
