What the 2024 FBI UCR record shows for Boulder County, CO
Position in the state cohort
Boulder County reported a lower violent-crime rate than most comparable Colorado counties
At 25.7 reported violent offenses per 100,000 residents in 2024, Boulder County ranks 38 of 45 — above 7 of the 44 other Colorado counties whose 2024 submission passes this site’s completeness test and carries a matched Census denominator. That is -67.3% against the cohort median of 78.5. Counties that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Offense mix
The reported mix leans further toward property offenses than the state cohort
Violent offenses are 10.1% of the 845 Part I offenses reported in Boulder County for 2024, against a median of 17.6% across comparable Colorado counties — a gap of 7.5 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.
2020–2024 direction
The reported violent-crime rate ended the window higher
Across 5 comparable reporting years, the rate moved from 24.2 per 100,000 in 2020 to 25.7 in 2024 (+6.3%). The highest observed value was 34.5 in 2021 and the lowest 24.2 in 2020. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
On a very large county row, county figures aggregate every participating agency inside the county. Participation is voluntary. Per-100,000 rates use a separately matched 2020 U.S. Census county population, never a Table 10 field; unmatched counties stay count-only. A large county line encloses very different communities.

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.
County Table 10 totals are voluntary agency filings: incomplete coverage is not a county crime measure, and a countywide figure is not a neighbourhood verdict.
