FBI Crime Data Explorer
The FBI's public portal for crime statistics collected from law enforcement agencies nationwide via the NIBRS reporting system.
The FBI Crime Data Explorer (formerly the Uniform Crime Reporting program) is the FBI's public data portal for crime statistics. It collects data from law enforcement agencies nationwide through the National Incident-Based Reporting System (NIBRS).
WhereAtHome sources crime rates from this data to categorize cities into crime tiers. Not all cities have complete FBI coverage — those without it receive curated tier assignments.
