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.
