The National Incident-Based Reporting System (NIBRS)

Since 1930, the Federal Bureau of Investigation’s (FBI’s) Uniform Crime Reporting (UCR) program has collected and published nationwide crime statistics. State and local law enforcement agencies, as well as federal agencies, voluntarily submit data on reported crimes that occur in their jurisdictions to UCR. UCR then compiles and publishes the data, and provides datasets and some trend analyses in a standardized format that legislators, researchers, and law enforcement agencies can access to better understand and address crime in the United States.
