Jefferson County, KS reported 114 violent crimes per 100,000 in FBI UCR 2024
According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Jefferson County, KS agencies reported 21 violent and 154 property offenses. That equals about 114 violent and 838 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
Jefferson County reported 21 violent offences in 2024 against a population of 18,368. 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 212.3 per 100,000 in 2021 to 114.3 in 2024 (-46.2%). The highest observed value was 223.2 in 2022 and the lowest 114.3 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 12.0% of the 175 Part I offenses reported in Jefferson County for 2024, against a median of 25.0% across comparable Kansas counties — a gap of 13.0 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 114.3 reported violent offenses per 100,000 residents in 2024, Jefferson County ranks 24 of 70 — above 46 of the 69 other Kansas counties whose 2024 submission passes this site’s completeness test and carries a matched Census denominator. That is +55.3% against the cohort median of 73.6. 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.
