Crime Statistics and Maps
Official Crime Statistics
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.
Other annual publications, such as Hate Crime Statistics and Law Enforcement Officers Killed and Assaulted address specialized facets of crime such as hate crime or the murder and assaults of law enforcement officers respectively.
Additional crime statistics summaries from the California Department of Justice (DOJ), Division of Criminal Justice, Criminal Justice Statistics Center (CJSC) are included in this section.
