Brown County, SD reported 34 violent crimes per 100,000 in FBI UCR 2024
According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Brown County, SD agencies reported 13 violent and 19 property offenses. That equals about 34 violent and 50 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
Brown County reported 13 violent offences in 2024 against a population of 38,301. 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 3 comparable reporting years, the rate moved from 20.9 per 100,000 in 2020 to 33.9 in 2024 (+62.5%). The highest observed value was 44.4 in 2022 and the lowest 20.9 in 2020. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Offense mix
Violent offenses are 40.6% of the 32 Part I offenses reported in Brown County for 2024, against a median of 25.0% across comparable South Dakota counties — a gap of 15.6 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 33.9 reported violent offenses per 100,000 residents in 2024, Brown County ranks 26 of 41 — above 15 of the 40 other South Dakota counties whose 2024 submission passes this site’s completeness test and carries a matched Census denominator. That is -21.4% against the cohort median of 43.2. 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 73.7% of reported property offenses in Brown County, against a cohort median of 60.0%. The remainder is burglary (0) and motor vehicle theft (5). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
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.
