Summary Reporting System (SRS) and the National Incident-Based Reporting System (NIBRS) are part of the FBI's Uniform Crime Reporting system. SRS and NIBRS collect data on crime incidents that are reported by law enforcement agencies across the country. Because SRS and NIBRS data are collected differently, they cannot be compared.
NIBRS was created in the 1980s to collect more detailed information on crime. Washington NIBRS data begins in 2012.
