They make the cohort position above checkable against named records instead of a generic state average.
Position in the state cohort
At 35.7 reported violent offenses per 100,000 residents in 2024, Castle Rock ranks 116 of 134 — above 18 of the 133 other Colorado cities whose 2024 submission passes this site’s completeness test. That is -82.4% against the cohort median of 202.8. Cities 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 5 comparable reporting years, the rate moved from 64.7 per 100,000 in 2020 to 35.7 in 2024 (-44.8%). The highest observed value was 64.7 in 2020 and the lowest 22.7 in 2023. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Offense mix
Violent offenses are 3.7% of the 819 Part I offenses reported in Castle Rock for 2024, against a median of 11.7% across comparable Colorado cities — a gap of 8.0 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.
Property-offense composition
Larceny-theft is 88.8% of reported property offenses in Castle Rock, against a cohort median of 76.8%. The remainder is burglary (52) and motor vehicle theft (36). Composition differences of this size usually track what kinds of places and property are present in a jurisdiction.
Property counts dominate Castle Rock's FBI UCR Table 8 municipal row. Per-100,000 rates use the reporting-year population on that row; cities that fail the completeness test stay out of rate rankings. A citywide figure rarely describes any single neighbourhood inside the municipal boundary.
