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.
SRS has been used since the 1930s to collect national crime data. Washington SRS data is available from 1994 to 2018. Data will no longer be produced from the SRS as of 2018.
