The Uniform Crime Reports (UCR) are official data on crime in the United States, published by the Federal Bureau of Investigation (FBI). UCR is "a nationwide, cooperative statistical effort of nearly 18,000 city, university and college, county, state, tribal, and federal law enforcement agencies voluntarily reporting data on crimes brought to their attention."
