Comparable rate records
The nearest comparable 2024 records to St. Ann's 406.5 violent-crime rate per 100,000 are Richland (403.0), Sugar Creek (410.0), Cameron (410.1), Rock Hill (411.4). 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.
Position in the state cohort
At 406.5 reported violent offenses per 100,000 residents in 2024, St. Ann ranks 62 of 272 — above 210 of the 271 other Missouri cities whose 2024 submission passes this site’s completeness test. That is +120.5% against the cohort median of 184.3. Cities that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Offense mix
Violent offenses are 25.1% of the 203 Part I offenses reported in St. Ann for 2024, against a median of 13.4% across comparable Missouri cities — a gap of 11.7 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.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 341.6 per 100,000 in 2020 to 406.5 in 2024 (+19.0%). The highest observed value was 510.4 in 2021 and the lowest 305.0 in 2022. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Property-offense composition
Larceny-theft is 65.8% of reported property offenses in St. Ann, against a cohort median of 78.6%. The remainder is burglary (18) and motor vehicle theft (34). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Property counts dominate St. Ann'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.
