Position in the state cohort
At 73.8 reported violent offenses per 100,000 residents in 2024, Jefferson County ranks 24 of 45 — above 21 of the 44 other Colorado counties whose 2024 submission passes this site’s completeness test and carries a matched Census denominator. That is -6.0% 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.
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.
