Decatur County, TN reported 131 violent crimes per 100,000 in FBI UCR 2024
According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Decatur County, TN agencies reported 15 violent and 60 property offenses. That equals about 131 violent and 525 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
Decatur County reported 15 violent offences in 2024 against a population of 11,435. 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.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 393.5 per 100,000 in 2020 to 131.2 in 2024 (-66.7%). The highest observed value was 393.5 in 2020 and the lowest 113.7 in 2023. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Offense mix
Violent offenses are 20.0% of the 75 Part I offenses reported in Decatur County for 2024, against a median of 29.0% across comparable Tennessee counties — a gap of 9.0 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-offense composition
Larceny-theft is 45.0% of reported property offenses in Decatur County, against a cohort median of 60.4%. The remainder is burglary (25) and motor vehicle theft (8). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Position in the state cohort
At 131.2 reported violent offenses per 100,000 residents in 2024, Decatur County ranks 49 of 92 — above 43 of the 91 other Tennessee counties whose 2024 submission passes this site’s completeness test and carries a matched Census denominator. That is -7.2% against the cohort median of 141.3. Counties that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Mid-size county rows still aggregate voluntary UCR submissions. Per-100,000 rates need a matched 2020 Census population; unmatched stay count-only. County-wide totals rarely describe any single town inside the line.
