Incomplete FBI reporting for this county
Law-enforcement agencies serving Brown County reported 0 violent and 0 property offences to the FBI for 2024 against a population of 6,244. 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 Brown County does not pass the completeness test this site applies for a population of 6,244. The counts below are shown because they are what agencies reported, but they are not treated here as the county’s crime level, and Brown County is excluded from rankings and comparisons on this site for 2024.
Small-count caution
Brown County reported 0 violent offences in 2024 against a population of 6,244. 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.
Small-county UCR rows are especially sensitive to which agencies filed. Per-100,000 rates use a matched 2020 Census population when available; otherwise counts only. Do not treat the county total as a town-level crime level.
