Small-count caution
River Forest reported 10 violent offences in 2024 against a population of 11,080. 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.
Comparable rate records
The nearest comparable 2024 records to River Forest's 90.3 violent-crime rate per 100,000 are Round Lake Park (90.4), Amboy (90.0), Schaumburg (90.8), Mount Prospect (89.7). 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.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 148.5 per 100,000 in 2020 to 90.3 in 2024 (-39.2%). The highest observed value was 148.5 in 2020 and the lowest 52.6 in 2022. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Offense mix
Violent offenses are 3.5% of the 284 Part I offenses reported in River Forest for 2024, against a median of 11.3% across comparable Illinois cities — a gap of 7.8 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
At 90.3 reported violent offenses per 100,000 residents in 2024, River Forest ranks 269 of 506 — above 237 of the 505 other Illinois cities whose 2024 submission passes this site’s completeness test. That is -10.4% against the cohort median of 100.7. 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 River Forest'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 10 reported violent incidents in a population of 11,080. 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.
