About CrimeByCounty
Free, accurate crime data for every US county.
Our Mission
CrimeByCounty provides free, transparent crime and safety data for every county in the United States. We believe that anyone — whether considering a move, researching their community, or studying public safety — deserves access to clear, accurate data.
Data Sources
Our primary data source is the FBI Uniform Crime Reporting (UCR) program, which collects crime statistics from thousands of law enforcement agencies across the country. We also incorporate data from County Health Rankings for supplemental safety metrics.
All crime rates are presented per 100,000 population to allow fair comparison across counties of different sizes. Safety scores (0–100) are composite metrics — higher scores indicate safer counties.
Part of the ByCounty Network
CrimeByCounty is part of the ByCounty Network — a suite of data sites covering property taxes, cost of living, income, health, schools, environmental risk, water quality, and more. Visit CountyScore.com for a comprehensive county report combining all data sources.
