The Uniform Crime Reporting (UCR) Program is a nationwide initiative in the United States that collects and compiles crime data from law enforcement agencies. Established in 1930, it aims to provide a reliable set of criminal statistics for use in law enforcement, research, and public policy. The UCR program categorizes crimes into two main groups: Part I offenses, which include serious crimes like murder and robbery, and Part II offenses, which cover less serious crimes. Data collected through the UCR is published annually in the FBI's Crime in the United States report. This information helps identify crime trends, allocate resources, and inform the public about safety issues. The UCR is an essential tool for understanding crime patterns and supporting efforts to improve community safety across the nation.
