The Uniform Crime Reporting System started in what decade?

The Uniform Crime Reporting (UCR) System began in the 1930s, specifically in 1930 when it was established by the International Association of Chiefs of Police. This system was created to provide a reliable nationwide statistic for use in law enforcement and to facilitate the tracking of crime trends over time. The UCR collects data on reported crimes and arrests, offering standardized information that can be utilized for comparative analysis across different jurisdictions.

The UCR serves as an essential tool for law enforcement agencies to assess crime patterns, allocate resources effectively, and inform public policy. It's significant to note that many of the options provided pertain to decades before or after the inception of the UCR, making the 1930s the correct timeframe for this foundational development in crime reporting.
