Mill Valley, CA carries a PlainCrime A safety grade with violent crime 73% below the U.S. average
According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Mill Valley, CA shows violent crime at 95.2 per 100,000 residents and property crime at 1,003.1 per 100,000. Violent crime runs 73% below the U.S. average. PlainCrime assigns grade A from those rates. Figures are voluntary agency submissions joined to population denominators; incomplete coverage can move the number.
2020–2024 direction
Across 4 comparable reporting years, the rate moved from 42.0 per 100,000 in 2020 to 95.2 in 2024 (+126.8%). The highest observed value was 95.2 in 2024 and the lowest 42.0 in 2020. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Small-count caution
Mill Valley reported 13 violent offences in 2024 against a population of 13,658. 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.
Position in the state cohort
At 95.2 reported violent offenses per 100,000 residents in 2024, Mill Valley ranks 420 of 458 — above 38 of the 457 other California cities whose 2024 submission passes this site’s completeness test. That is -71.4% against the cohort median of 333.1. Cities that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Comparable rate records
The nearest comparable 2024 records to Mill Valley's 95.2 violent-crime rate per 100,000 are Lincoln (96.2), Eastvale (93.4), Hillsborough (93.2), Yorba Linda (93.2). 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.
Offense mix
Violent offenses are 8.7% of the 150 Part I offenses reported in Mill Valley for 2024, against a median of 17.1% across comparable California cities — a gap of 8.4 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 is 78.8% of reported property offenses in Mill Valley, against a cohort median of 69.5%. The remainder is burglary (25) and motor vehicle theft (4). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Property counts dominate Mill Valley'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 13 reported violent incidents in a population of 13,658. 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.
