The verdict
Herculaneum earns a B safety grade: violent crime runs 43% below the U.S. average, placing it close to the national middle for violent crime.
Based on 11 reported violent incidents in a population of 5,436. 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.
Small-count caution
Herculaneum reported 11 violent offences in 2024 against a population of 5,436. 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 Herculaneum's 202.4 violent-crime rate per 100,000 are Liberty (203.3), Bethany (204.9), Hillsboro (199.7), St. Peters (206.7). 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 355.8 per 100,000 in 2020 to 202.4 in 2024 (-43.1%). The highest observed value was 391.2 in 2021 and the lowest 111.0 in 2023. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Position in the state cohort
At 202.4 reported violent offenses per 100,000 residents in 2024, Herculaneum ranks 130 of 272 — above 142 of the 271 other Missouri cities whose 2024 submission passes this site’s completeness test. That is +9.8% 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.
Property counts dominate Herculaneum'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.

Small-city offense counts above are voluntary UCR submissions, not neighbourhood advice. Year-to-year swings can look large when the population base is modest.
