Incomplete FBI reporting for this county
Law-enforcement agencies serving Black Hawk County reported 7 violent and 97 property offences to the FBI for 2024 against a population of 131,144. Reporting to the UCR Program is voluntary, and figures this low for a population this size mean agencies did not submit complete data, not that little crime occurred. The numbers below are what was reported; they are not a measure of this county's crime level, and no safety grade is assigned from them.
Reporting completeness
FBI UCR participation is voluntary, and the 2024 submission covering Black Hawk County does not pass the completeness test this site applies for a population of 131,144. The counts below are shown because they are what agencies reported, but they are not treated here as the county’s crime level, and Black Hawk County is excluded from rankings and comparisons on this site for 2024.
Small-count caution
Black Hawk County reported 7 violent offences in 2024 against a population of 131,144. At this volume one additional or one fewer report moves the per-100,000 rate noticeably, so the figure is better read as a data point than as a precise measurement, and year-to-year swings here are expected.
2020–2023 direction
Across 4 comparable reporting years, the rate moved from 32.0 per 100,000 in 2020 to 11.4 in 2023 (-64.3%). The highest observed value was 32.0 in 2020 and the lowest 11.4 in 2023. Years whose submission failed the completeness test are left out of this comparison rather than plotted as change.
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.
