Seneca County, OH reported 25 violent crimes per 100,000 in FBI UCR 2024
According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Seneca County, OH agencies reported 14 violent and 124 property offenses. That equals about 25 violent and 225 property crimes per 100,000 using a verified Census population join. Table 10 coverage is a voluntary subset of U.S. counties.
Small-count caution
Seneca County reported 14 violent offences in 2024 against a population of 55,069. 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.
2021–2024 direction
Across 4 comparable reporting years, the rate moved from 14.5 per 100,000 in 2021 to 25.4 in 2024 (+75.0%). The highest observed value was 32.7 in 2022 and the lowest 14.5 in 2021. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Position in the state cohort
At 25.4 reported violent offenses per 100,000 residents in 2024, Seneca County ranks 50 of 66 — above 16 of the 65 other Ohio counties whose 2024 submission passes this site’s completeness test and carries a matched Census denominator. That is -43.3% against the cohort median of 44.8. Counties that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Property-offense composition
Larceny-theft is 83.9% of reported property offenses in Seneca County, against a cohort median of 71.6%. The remainder is burglary (15) and motor vehicle theft (5). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Offense mix
Violent offenses are 10.1% of the 138 Part I offenses reported in Seneca County for 2024, against a median of 15.0% across comparable Ohio counties — a gap of 4.8 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.
On a 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.
