FBI Releases 2021 Crime in the Nation Statistics | Federal Bureau of Investigation

In anticipation of UCR’s evolution to NIBRS, the FBI collaborated with the Bureau of Justice Statistics (BJS) to develop comprehensive methodologies to bring a NIBRS estimation process to fruition and establish 2021 as the first year in which all crime estimates can be based on NIBRS data. Together, the FBI and BJS developed and tested statistical procedures that assess the quality and completeness of NIBRS data, created methods to adjust for non-transitioned agencies, crafted estimation procedures for generating reliable and accurate national indicators as new agencies report NIBRS data, and established a semi-automated system for producing national estimates of key crime indicators on an annual basis.

To provide a confident comparison of crime trends across the nation, the UCR Program performed a NIBRS estimation crime trend analysis. The analysis used NIBRS estimation data of violent and property crimes from 2020 and 2021.

Overall, the analysis shows violent and property crime remained consistent between 2020 and 2021. While the aggregate estimated violent crime volume decreased 1% for the nation from 1,326,600 in 2020 to 1,313,200 in 2021, the estimated number of murders increased from 22,000 in 2020 to 22,900 in 2021. The increase of murders constitutes a 4.3% increase. The robbery rate decreased 8.9% from 2020 to 2021, which heavily contributed to the decrease in overall violent crime despite increases in murder and rape rates at the national level. It is important to note that these estimated trends are not considered statistically significant by NIBRS estimation methods. The nonsignificant nature of the observed trends is why, despite these described changes, the overall message is that crime remained consistent.
