Position in the state cohort
Mariposa County reported a higher violent-crime rate than most comparable California counties
At 548.7 reported violent offenses per 100,000 residents in 2024, Mariposa County ranks 2 of 56 — above 54 of the 55 other California counties whose 2024 submission passes this site’s completeness test and carries a matched Census denominator. That is +371.3% against the cohort median of 116.4. Counties that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
2020–2024 direction
The reported violent-crime rate ended the window higher
Across 4 comparable reporting years, the rate moved from 356.1 per 100,000 in 2020 to 548.7 in 2024 (+54.1%). The highest observed value was 577.9 in 2023 and the lowest 356.1 in 2020. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Offense mix
Violent offenses make up an unusually large share of the reported mix
Violent offenses are 34.7% of the 271 Part I offenses reported in Mariposa County for 2024, against a median of 29.6% across comparable California counties — a gap of 5.1 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.
Mid-size county rows still aggregate voluntary UCR submissions. Per-100,000 rates need a matched 2020 Census population; unmatched stay count-only. County-wide totals rarely describe any single town inside the line.
