Bureau of Justice Statistics The Bureau of Justice Statistics (BJS), in partnership with the Federal Bureau of Investigation’s (FBI) Criminal Justice Information Systems (CJIS), is spearheading the National Crime Statistics Exchange (NCS-X), a program designed to generate nationally-representative incident-based data on crimes reported to law enforcement agencies. NCS-X will leverage the FBI’s existing National Incident-Based Reporting System (NIBRS) by recruiting a sample of 400 law enforcement agencies to supplement the existing NIBRS data by providing their incident data to their state (or the federal) NIBRS data collection program. When data from these 400 agencies are combined with data from the more than 6,600 agencies that currently report NIBRS data to the FBI, NIBRS will be able to produce national estimates of crime that can be disaggregated by victim-offender characteristics, the circumstances of the event, victim-offender relationship, and other important elements of criminal events. When completed, nationally representative NIBRS data will increase our nation’s ability to monitor, respond to, and prevent crime by allowing NIBRS to produce timely, detailed, and accurate national measures of crime incidents.
Uniform Crime Reporting Program The Uniform Crime Reporting (UCR) 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.
