Position in the state cohort
At 431.8 reported violent offenses per 100,000 residents in 2024, Northglenn ranks 30 of 134 — above 104 of the 133 other Colorado cities whose 2024 submission passes this site’s completeness test.

2020–2024 direction
Across 5 comparable reporting years, the rate moved from 513.3 per 100,000 in 2020 to 431.8 in 2024 (-15.9%). The highest observed value was 661.4 in 2021 and the lowest 431.8 in 2024. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Property counts dominate Northglenn'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.
