Most crime never reaches the police, so these are reported crimes, a floor rather than the full count. In 2024 about half of violent crimes (48%) and about 3 in 10 property crimes (31%) were reported to police (U.S. Justice Department, National Crime Victimization Survey). Rates also depend on how completely each agency reports to the FBI. County figures add up the city police and sheriff reports in the county (3 agencies; 100% of residents covered).
