Small-count caution
Isleton reported 7 violent offences in 2024 against a population of 770. 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 909.1 reported violent offenses per 100,000 residents in 2024, Isleton ranks 28 of 458 — above 430 of the 457 other California cities whose 2024 submission passes this site’s completeness test. That is +176.8% 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 589.6 per 100,000 in 2020 to 909.1 in 2024 (+54.2%). The highest observed value was 2146.5 in 2022 and the lowest 0.0 in 2021. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Comparable rate records
The nearest comparable 2024 records to Isleton's 909.1 violent-crime rate per 100,000 are Lynwood (910.0), Santa Fe Springs (905.8), Signal Hill (912.5), Bishop (915.2). 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.
Property-offense composition
Larceny-theft is 41.2% of reported property offenses in Isleton, against a cohort median of 69.5%. The remainder is burglary (20) and motor vehicle theft (0). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Property counts dominate Isleton'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 7 reported violent incidents in a population of 770. 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.
On a small municipal row, small denominators make rates sensitive to a handful of incidents. Figures are reported totals, not neighbourhood advice.
