What original system did the FBI create in the 1930s to collect data on crime?

The correct answer is the Uniform Crime Report (UCR), which the FBI developed in the 1930s as a standardized system for collecting and reporting crime data across the United States. The UCR was initiated to provide a consistent method for compiling crime statistics, enabling law enforcement agencies to share information and track crime trends nationally. This system primarily focuses on seven major crime categories, known as Part I offenses, which include serious crimes like murder, rape, and robbery.

The significance of the UCR lies in its role as a foundational tool for law enforcement agencies and policymakers. It has been instrumental in highlighting crime patterns, informing public policy, and helping law enforcement allocate resources effectively.

Other options, such as the National Incident-Based Reporting System (NIBRS) and the Crime Victimization Survey, were developed later to enhance or complement the data collection efforts initiated by the UCR. The Part I Index Crimes Report refers specifically to the first part of the UCR that lists serious crimes, but it is not the name of the system as a whole. Thus, the UCR stands out as the original system designed by the FBI to gather comprehensive crime data during that time period.
