Estimates Will Help Fill in Crime Statistics Gap

"When the annual Crime in the United States (CIUS), 2021 data is released this fall, it will look different from previous releases. CIUS 2021 will only represent state-level data and federal data reported by law enforcement. In conjunction with CIUS, the FBI will release a trend study that will look at a year-over-year change in violent crime and property crime.

The reason for the change is that not every law enforcement agency in the U.S. has successfully moved to the National Incident-Based Reporting System (NIBRS) for reporting their crime data to the FBI. With support from the FBI, some agencies have been reporting crime statistics via NIBRS for more than 20 years. After the CJIS Advisory Policy Board adopted the recommendation in 2015 to retire the traditional Summary Reporting System and transition to the more comprehensive NIBRS by January 2021, more agencies made the switch to NIBRS reporting. Every state is now NIBRS compliant and can accept NIBRS data. A few major cities, however, are still working on the transition.

Crime estimates will fill in the gaps where data is not available this year. Estimation has been associated with the release for more than 50 years. This year, FBI data experts will use robust estimation tools, developed in collaboration with the Department of Justice's Bureau of Justice Statistics, to create the most accurate crime estimates possible during this transition period..."
