From the FBI's website, " The program has been the starting place for law enforcement executives, students of criminal justice, researchers, members of the media, and the public at large seeking information on crime in the nation. The program was conceived in 1929 by the International Association of Chiefs of Police to meet the need for reliable uniform crime statistics for the nation. In 1930, the FBI was tasked with collecting, publishing, and archiving those statistics."
The Bureau of Justice Statistics was first established on December 27, 1979 under the Justice Systems Improvement Act of 1979, Public Law 96-157 (the 1979 Amendment to the Omnibus Crime Control and Safe Streets Act of 1968, Public Law 90-351).

These data are critical to federal, state, and local policymakers in combating crime and ensuring that justice is both efficient and evenhanded."
