Years of Data Used
Uniform Crime Reporting - FBI
The Uniform Crime Reporting (UCR) Program was conceived in 1929 by the International Association of Chiefs of Police to meet a need for reliable, uniform crime statistics for the nation. In 1930, the FBI was tasked with collecting, publishing, and archiving those statistics. Today, several annual statistical publications, such as the comprehensive Crime in the United States, are produced from data provided by nearly 17,000 law enforcement agencies across the United States. The County Health Rankings use data from the County-Level Detailed Arrest and Offense Data report.
In most states, there is data on violent crime offenses reported by jurisdictions. When available, we link to these resources in our Finding More Data section.
