Data updated 2026-09-05
Seneca, MO is among the highest-crime cities in the country, and earns a D PlainCrime safety grade, where violent crime runs 47% above the U.S. average
According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Seneca, MO shows violent crime at 519 per 100,000 residents and property crime at 1,254.3 per 100,000. Violent crime runs 47% above the U.S. average. PlainCrime assigns grade D from those rates. Figures are voluntary agency submissions joined to population denominators; incomplete coverage can move the number.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 209.0 per 100,000 in 2020 to 519.0 in 2024 (+148.3%). The highest observed value was 519.0 in 2024 and the lowest 83.3 in 2021. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Small-count caution
Seneca reported 12 violent offences in 2024 against a population of 2,312. 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 Seneca's 519.0 violent-crime rate per 100,000 are Overland (527.4), Byrnes Mill (501.9), De Soto (537.7), Nevada (543.7). 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.
Position in the state cohort
At 519.0 reported violent offenses per 100,000 residents in 2024, Seneca ranks 45 of 272 — above 227 of the 271 other Missouri cities whose 2024 submission passes this site’s completeness test. That is +181.6% 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 29.3% of the 41 Part I offenses reported in Seneca for 2024, against a median of 13.4% across comparable Missouri cities — a gap of 15.8 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.
Property counts dominate Seneca'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 12 reported violent incidents in a population of 2,312. 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.
On a small municipal row, small denominators make rates sensitive to a handful of incidents. Figures are reported totals, not neighbourhood advice.
