What the 2024 FBI UCR record shows for Ada County, ID
Position in the state cohort
Ada County reported a lower violent-crime rate than most comparable Idaho counties
At 43.6 reported violent offenses per 100,000 residents in 2024, Ada County ranks 28 of 33 — above 5 of the 32 other Idaho counties whose 2024 submission passes this site’s completeness test and carries a matched Census denominator. That is -45.0% against the cohort median of 79.3. Counties that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
Share of the state cohort
Ada County carries a large share of the reporting cohort’s total offenses
The 754 Part I offenses reported here are 17.2% of the 4,373 reported across all 33 comparable Idaho counties in 2024. A county this large moves the statewide total on its own, so state-level changes should be read against its population of 494,967 rather than as a uniform shift.
2020–2024 direction
The reported violent-crime rate ended the window lower
Across 5 comparable reporting years, the rate moved from 49.1 per 100,000 in 2020 to 43.6 in 2024 (-11.1%). The highest observed value was 57.4 in 2022 and the lowest 43.6 in 2024. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
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.

FBI Table 10 supplies county offense counts but no resident population. Where this page shows a per-100,000 rate, the denominator is a separately matched 2020 U.S. Census Bureau county population; unmatched county rows remain count-only. Statewide comparisons draw on the state UCR program. Verify with FBI.gov UCR and Census.gov QuickFacts.
County Table 10 totals are voluntary agency filings: incomplete coverage is not a county crime measure, and a countywide figure is not a neighbourhood verdict.
