Union County, TN reported 91 violent crimes per 100,000 in FBI UCR 2024
According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Union County, TN agencies reported 18 violent and 145 property offenses. That equals about 91 violent and 732 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
Union County reported 18 violent offences in 2024 against a population of 19,802. 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 212.1 per 100,000 in 2020 to 90.9 in 2024 (-57.1%). The highest observed value was 212.1 in 2020 and the lowest 90.9 in 2024. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Offense mix
Violent offenses are 11.0% of the 163 Part I offenses reported in Union County for 2024, against a median of 29.0% across comparable Tennessee counties — a gap of 18.0 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.
Position in the state cohort
At 90.9 reported violent offenses per 100,000 residents in 2024, Union County ranks 65 of 92 — above 27 of the 91 other Tennessee counties whose 2024 submission passes this site’s completeness test and carries a matched Census denominator. That is -35.7% 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.

FBI Table 10 supplies county offense counts but no resident population. Where this page shows a per-100,000 rate, the denominator is a separately matched 2020 U.S. Census Bureau county population; unmatched county rows remain count-only.
