What the 2024 FBI UCR record shows for Linn County, IA
Position in the state cohort
Linn County reported a lower violent-crime rate than most comparable Iowa counties
At 13.5 reported violent offenses per 100,000 residents in 2024, Linn County ranks 76 of 86 — above 10 of the 85 other Iowa counties whose 2024 submission passes this site’s completeness test and carries a matched Census denominator. That is -70.9% against the cohort median of 46.3. Counties that did not report, or that reported implausibly low totals, are excluded from this cohort rather than counted as low-crime.
2020–2024 direction
The reported violent-crime rate ended the window higher
Across 5 comparable reporting years, the rate moved from 12.2 per 100,000 in 2020 to 13.5 in 2024 (+10.7%). The highest observed value was 16.5 in 2021 and the lowest 12.2 in 2020. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
Offense mix
The reported mix leans further toward property offenses than the state cohort
Violent offenses are 20.8% of the 149 Part I offenses reported in Linn County for 2024, against a median of 24.5% across comparable Iowa counties — a gap of 3.7 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.
On a 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.
