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 consistent framework for reporting and analyzing crime statistics, helping to identify trends and patterns in criminal activity across different regions. 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 severe crimes such as vandalism and drug offenses. This data is used by policymakers, researchers, and law enforcement to enhance public safety and allocate resources effectively.
