Small-count caution
Custer County reported 2 violent offences in 2024 against a population of 4,275. 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 163.7 per 100,000 in 2020 to 46.8 in 2024 (-71.4%). The highest observed value was 210.5 in 2021 and the lowest 23.4 in 2023. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Position in the state cohort
At 46.8 reported violent offenses per 100,000 residents in 2024, Custer County ranks 26 of 33 — above 7 of the 32 other Idaho counties whose 2024 submission passes this site’s completeness test and carries a matched Census denominator. That is -41.0% against the cohort median of 79.3. Counties that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Offense mix
Violent offenses are 22.2% of the 9 Part I offenses reported in Custer County for 2024, against a median of 29.9% across comparable Idaho counties — a gap of 7.7 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-county UCR rows are especially sensitive to which agencies filed. Per-100,000 rates use a matched 2020 Census population when available; otherwise counts only. Do not treat the county total as a town-level crime level.

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. Statewide comparisons draw on the state UCR program. Verify with FBI.gov UCR and Census.gov QuickFacts.
