What the 2024 FBI UCR record shows for Rancho Cucamonga, CA
Comparable rate records
Rancho Cucamonga's closest reported-rate comparisons are in the California cohort
The nearest comparable 2024 records to Rancho Cucamonga's 293.7 violent-crime rate per 100,000 are West Sacramento (293.6), Vacaville (293.2), Morro Bay (294.3), Daly City (296.3). 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 14.0% of the 3,669 Part I offenses reported in Rancho Cucamonga for 2024, against a median of 17.1% across comparable California cities — a gap of 3.2 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.
Position in the state cohort
Rancho Cucamonga sits mid-pack among comparable California cities
At 293.7 reported violent offenses per 100,000 residents in 2024, Rancho Cucamonga ranks 258 of 458 — above 200 of the 457 other California cities whose 2024 submission passes this site’s completeness test. That is -11.8% 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.
2020–2024 direction
The reported violent-crime rate ended the window lower
Across 4 comparable reporting years, the rate moved from 308.0 per 100,000 in 2020 to 293.7 in 2024 (-4.6%). The highest observed value was 370.5 in 2022 and the lowest 121.9 in 2023. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Property counts dominate Rancho Cucamonga'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.
On a large city row, these are citywide reported offense totals - not neighbourhood advice. Conditions vary by place and time; reporting rates differ across jurisdictions.
