The FBI Uniform Crime Reporting (UCR) program is a nationwide initiative that collects and compiles crime data from law enforcement agencies across the United States. 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 program is published annually in the Crime in the United States report. This report helps to identify crime trends, inform law enforcement strategies, and guide community safety initiatives. The UCR program is an essential tool for understanding crime patterns and improving public safety across the nation.
