Figures are voluntary agency submissions joined to population denominators; incomplete coverage can move the number.
Small-count caution
Rio Dell reported 12 violent offences in 2024 against a population of 3,283. At this volume one additional or one fewer report moves the per-100,000 rate noticeably, so the figure is better read as a data point than as a precise measurement, and year-to-year swings here are expected.
Comparable rate records
The nearest comparable 2024 records to Rio Dell's 365.5 violent-crime rate per 100,000 are Pismo Beach (366.6), Paso Robles (364.3), La Habra (363.0), San Fernando (362.5). These are same-year agency submissions that pass the same completeness screen, not a claim that the cities have identical conditions. They make the cohort position above checkable against named records instead of a generic state average.
Property-offense composition
Larceny-theft is 90.6% of reported property offenses in Rio Dell, against a cohort median of 69.5%. The remainder is burglary (2) and motor vehicle theft (3). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Position in the state cohort
At 365.5 reported violent offenses per 100,000 residents in 2024, Rio Dell ranks 210 of 458 — above 248 of the 457 other California cities whose 2024 submission passes this site’s completeness test. That is +11.3% against the cohort median of 328.5. Cities that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 358.5 per 100,000 in 2020 to 365.5 in 2024 (+1.9%). The highest observed value was 620.9 in 2022 and the lowest 87.1 in 2021. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Property counts dominate Rio Dell's FBI UCR Table 8 municipal row. Per-100,000 rates use the reporting-year population on that row; cities that fail the completeness test stay out of rate rankings. A citywide figure rarely describes any single neighbourhood inside the municipal boundary.
Based on 12 reported violent incidents in a population of 3,283. At this volume, one additional or one fewer report can shift the rate and letter grade noticeably; small-city crime counts are inherently more volatile year to year than large-city counts, so treat this grade as a data point, not a precise ranking.
Small-city offense counts above are voluntary UCR submissions, not neighbourhood advice. Year-to-year swings can look large when the population base is modest.
