According to the FBI Uniform Crime Reporting (UCR) Program for 2024, St. Louis County, MO agencies reported 1,904 violent and 6,037 property offenses.

Share of the state cohort
The 7,941 Part I offenses reported here are 37.5% of the 21,193 reported across all 77 comparable Missouri counties in 2024. A county this large moves the statewide total on its own, so state-level changes should be read against its population of 1,004,125 rather than as a uniform shift.
Position in the state cohort
At 189.6 reported violent offenses per 100,000 residents in 2024, St. Louis County ranks 21 of 77 — above 56 of the 76 other Missouri counties whose 2024 submission passes this site’s completeness test and carries a matched Census denominator. That is +53.8% against the cohort median of 123.3. Counties that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
On a very large county row, county figures aggregate every participating agency inside the county. Participation is voluntary. Per-100,000 rates use a separately matched 2020 U.S. Census county population, never a Table 10 field; unmatched counties stay count-only. A large county line encloses very different communities.

FBI Table 10 supplies county offense counts but no resident population. Where this page shows a per-100,000 rate, the denominator is a separately matched 2020 U.S. Census Bureau county population; unmatched county rows remain count-only.
