Criminal justice research relies on a range of data sources, each offering insight into crime, victimization, law enforcement, and the courts. This talk, hosted by the American Statistical Association (ASA) provides an overview of datasets used in the field, spanning national, state, and local levels. Dr. Ridgeway will discuss major federal sources, including the FBI’s Summary Reporting System (SRS), National Incident-Based Reporting System (NIBRS) as well as the Bureau of Justice Statistics’ National Crime Victimization Survey (NCVS). In addition, Dr. Ridgeway will highlight city-level open data portals, which provide granular insights into local criminal justice patterns. Finally, the talk will present a few “specialty” datasets that capture critical aspects of the system, such as North Carolina’s adult conviction records, Florida court data, Pennsylvania Sentencing Commission data, and New Jersey’s use-of-force reporting. By exploring these resources, attendees will gain a deeper understanding of the strengths, limitations, and opportunities presented by modern criminal justice data.
