National Crime Statistics Exchange (NCS-X)



The National Crime Statistics Exchange (NCS-X) is an initiative to develop a statistical system of incident-based data, on crimes reported to law enforcement, to generate nationally representative estimates of the volume and characteristics of crimes. NCS-X data will capture the attributes and circumstances of criminal incidents at the national level, allowing for more detailed and transparent descriptions of victimization and offending that will improve the nation’s ability to monitor, respond to, and prevent crime.

NCS-X was implemented in two phases, (1) obtaining incident-based crime data by expanding coverage of the FBI’s National Incident-Based Reporting System (NIBRS), and (2) developing statistical estimation procedures that provide a national picture of the details and context of crime.

As of January 1, 2021, the FBI Uniform Crime Reporting (UCR) Program retired the Summary Reporting System (SRS), the system for collecting reported crime data from law enforcement that had been in place for more than 90 years. NIBRS is now the national standard by which law enforcement agencies submit crime data to the FBI.
