According to the FBI Uniform Crime Reporting (UCR) Program for 2024, Summit County, CO agencies reported 30 violent and 150 property offenses.

Property-offense composition
Larceny-theft is 88.7% of reported property offenses in Summit County, against a cohort median of 68.2%. The remainder is burglary (12) and motor vehicle theft (5). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
2020–2024 direction
Across 5 comparable reporting years, the rate moved from 125.6 per 100,000 in 2020 to 96.6 in 2024 (-23.1%). The highest observed value was 128.8 in 2021 and the lowest 93.4 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 96.6 reported violent offenses per 100,000 residents in 2024, Summit County ranks 17 of 45 — above 28 of the 44 other Colorado counties whose 2024 submission passes this site’s completeness test and carries a matched Census denominator. That is +27.3% against the cohort median of 75.9. 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.
