Crime rates stayed constant from 2020 to 2021, according to new estimations from the FBI and Bureau of Justice Statistics. However, national crime data remains incomplete with about 37% of law enforcement agencies not reporting data last year.

In 2020, the FBI switched data collection methods from the Uniform Crime Reporting database to the National Incident-Based Reporting System (NIBRS). The NIBRS system requires agencies to submit more detailed data, which has caused the transition to the new system to be slow. In 2021, about 63% of law enforcement agencies submitted NIBRS data to the FBI.

To compensate for the lower participation rate, the FBI partnered with the Bureau of Justice Statistics to create crime rate estimations for 2021. The agencies used the existing NIBRS data along with the National Victimization Survey to create national crime rate estimates.

How much violent crime was there in 2021?

The FBI divides violent crime into four categories: homicide, rape, robbery, and aggravated assault. Aggravated assault and robberies are the two most common crimes in the category, making up almost 90% of all violent crime in the US. Homicides are the least common, making up about 1% of total violent crime.

The FBI report estimated that there were about 1.3 million violent crimes committed in 2021. This is about a 1% decrease from 2020. This drop in violent crime was driven by a 9% decrease in the robbery rate.

The violent crime rate in 2021 was about 396 violent crimes per 100,000 people. This continues the downward trend over the past three decades. Violent crime reached a peak in 1992 with almost 2 million offenses reported, or a rate of 750 crimes per 100,000 people. Most of this drop came from decreases in aggravated assault and robbery in that time.

How does violent crime compare between cities?

While there is not complete data for all cities, the FBI released reported violent crime rates for about 150 US cities with populations over 100,000. The largest cities on the list include Las Vegas, San Diego, and Dallas.

Mobile, Alabama, had the highest violent crime rate of all the cities on the list, with 2,042 violent crimes per 100,000 residents. Memphis, Tennessee, and Detroit, Michigan, had the next highest at just over 1,000 crimes per 100,000 residents.
