What the 2024 FBI UCR record shows for Marin County, CA
Position in the state cohort
Marin County reported a lower violent-crime rate than most comparable California counties
At 30.1 reported violent offenses per 100,000 residents in 2024, Marin County ranks 51 of 56 — above 5 of the 55 other California counties whose 2024 submission passes this site’s completeness test and carries a matched Census denominator. That is -76.8% against the cohort median of 129.8. Counties that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Offense mix
The reported mix leans further toward property offenses than the state cohort
Violent offenses are 16.4% of the 482 Part I offenses reported in Marin County for 2024, against a median of 29.6% across comparable California counties — a gap of 13.2 points. Offense mix is shaped by which agencies report and how incidents are classified as well as by the underlying offenses, so it describes the reported record rather than a settled difference in conditions.
Property-offense composition
Larceny-theft dominates the property total more than it does across the cohort
Larceny-theft is 85.6% of reported property offenses in Marin County, against a cohort median of 65.6%. The remainder is burglary (54) and motor vehicle theft (4). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
2020–2024 direction
The reported violent-crime rate ended the window lower
Across 4 comparable reporting years, the rate moved from 34.3 per 100,000 in 2020 to 30.1 in 2024 (-12.2%). The highest observed value was 34.3 in 2020 and the lowest 23.3 in 2023. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
On a very large county row, county figures aggregate every participating agency inside the county. Participation is voluntary. Per-100,000 rates use a separately matched 2020 U.S. Census county population, never a Table 10 field; unmatched counties stay count-only. A large county line encloses very different communities.
