What the 2024 FBI UCR record shows for San Dimas, CA
Comparable rate records
San Dimas's closest reported-rate comparisons are in the California cohort
The nearest comparable 2024 records to San Dimas's 282.6 violent-crime rate per 100,000 are Cathedral City (283.3), Dixon (283.5), Walnut Creek (280.5), Orland (285.1). 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
The reported mix leans further toward property offenses than the state cohort
Violent offenses are 11.0% of the 835 Part I offenses reported in San Dimas for 2024, against a median of 17.1% across comparable California cities — a gap of 6.1 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.
2020–2024 direction
The reported violent-crime rate ended the window higher
Across 4 comparable reporting years, the rate moved from 246.7 per 100,000 in 2020 to 282.6 in 2024 (+14.6%). The highest observed value was 325.1 in 2023 and the lowest 246.7 in 2020. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Position in the state cohort
San Dimas sits mid-pack among comparable California cities
At 282.6 reported violent offenses per 100,000 residents in 2024, San Dimas ranks 271 of 458 — above 187 of the 457 other California cities whose 2024 submission passes this site’s completeness test. That is -15.2% 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.
Property counts dominate San Dimas'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.
Mid-size municipal totals above are reported offenses, not safety advice for any single block. Reporting completeness still varies by year and agency.
