Position in the state cohort
Montclair reported a higher violent-crime rate than most comparable California cities
At 644.1 reported violent offenses per 100,000 residents in 2024, Montclair ranks 72 of 458 — above 386 of the 457 other California cities whose 2024 submission passes this site’s completeness test. That is +96.1% 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
The reported violent-crime rate ended the window higher
Across 5 comparable reporting years, the rate moved from 622.6 per 100,000 in 2020 to 644.1 in 2024 (+3.5%). The highest observed value was 768.2 in 2023 and the lowest 368.2 in 2021. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Property counts dominate Montclair'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.
