Small-count caution
St. Clair County reported 9 violent offences in 2024 against a population of 9,284. 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.
2020–2024 direction
Across 4 comparable reporting years, the rate moved from 258.5 per 100,000 in 2020 to 96.9 in 2024 (-62.5%). The highest observed value was 258.5 in 2020 and the lowest 86.2 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 10.0% of the 90 Part I offenses reported in St. Clair County for 2024, against a median of 26.5% across comparable Missouri counties — a gap of 16.5 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 96.9 reported violent offenses per 100,000 residents in 2024, St. Clair County ranks 49 of 77 — above 28 of the 76 other Missouri counties whose 2024 submission passes this site’s completeness test and carries a matched Census denominator. That is -24.7% against the cohort median of 128.8. Counties that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Small-county UCR rows are especially sensitive to which agencies filed. Per-100,000 rates use a matched 2020 Census population when available; otherwise counts only. Do not treat the county total as a town-level crime level.
