About this data
- Counts are arrests, not people. One person arrested twice counts twice; an arrest with several charges counts once, under the most serious charge.
- Reported agencies only. Figures cover the ~14,500 agencies in the FBI's 2024 Uniform Crime Reporting arrest (ASR) file — about 94–95% of the FBI's official national total, which additionally counts agencies that report only through NIBRS. Nothing here is estimated for non-reporting agencies, so totals slightly undercount and are not strictly comparable across areas with different reporting coverage.
- Location is the arresting agency's headquarters, not where the arrest happened. Multi-jurisdiction agencies (state police, sheriffs, transit police) concentrate in one county — county figures are approximate, and about 3% of arrests come from agencies that can't be placed in any county.
- Race and ethnicity are reported separately from the age/sex counts, and not for every arrest — race is reported for ≈95% of arrests, ethnicity for ≈81%. Shares here use those reported subtotals as denominators.
- No per-capita rates. Because reporting coverage varies by area, population-adjusted rates would mislead; we show counts only. Arrests measure enforcement activity, not crime rates.
