Position in the state cohort
At 353.1 reported violent offenses per 100,000 residents in 2024, Nampa ranks 8 of 55 — above 47 of the 54 other Idaho cities whose 2024 submission passes this site’s completeness test. That is +83.4% against the cohort median of 192.6. Cities that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Comparable rate records
The nearest comparable 2024 records to Nampa's 353.1 violent-crime rate per 100,000 are Idaho Falls (356.5), Heyburn (348.2), Emmett (342.2), Pocatello (341.2). These are same-year agency submissions that pass the same completeness screen, not a claim that the cities have identical conditions. They make the cohort position above checkable against named records instead of a generic state average.
Offense mix
Violent offenses are 32.2% of the 1,303 Part I offenses reported in Nampa for 2024, against a median of 21.6% across comparable Idaho cities — a gap of 10.7 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 68.5% of reported property offenses in Nampa, against a cohort median of 77.0%. The remainder is burglary (180) and motor vehicle theft (98). 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 323.4 per 100,000 in 2020 to 353.1 in 2024 (+9.2%). The highest observed value was 383.2 in 2023 and the lowest 323.4 in 2020. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
