Roberts County, SD reported 136 violent crimes per 100,000 in FBI UCR 2024
According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Roberts County, SD agencies reported 14 violent and 7 property offenses. That equals about 136 violent and 68 property crimes per 100,000 using a verified Census population join. Table 10 coverage is a voluntary subset of U.S. counties.
Offense mix
Violent offenses are 66.7% of the 21 Part I offenses reported in Roberts County for 2024, against a median of 25.0% across comparable South Dakota counties — a gap of 41.7 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.
Small-count caution
Roberts County reported 14 violent offences in 2024 against a population of 10,280. 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.
Position in the state cohort
At 136.2 reported violent offenses per 100,000 residents in 2024, Roberts County ranks 2 of 41 — above 39 of the 40 other South Dakota counties whose 2024 submission passes this site’s completeness test and carries a matched Census denominator. That is +217.7% against the cohort median of 42.9. Counties that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
2020–2024 direction
Across 3 comparable reporting years, the rate moved from 223.7 per 100,000 in 2020 to 136.2 in 2024 (-39.1%). The highest observed value was 223.7 in 2020 and the lowest 136.2 in 2023. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
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.
