This report examines changes in crime rates in 34 American cities during calendar year 2020, with a special emphasis on homicide and other violent crimes. The current study updates previous studies by the authors with additional data through December 2020. The study was conducted by criminologist and Professor Emeritus Richard Rosenfeld and Ernesto Lopez of the University of Missouri – St. Louis and Thomas Abt, Commission Director and Council on Criminal Justice Senior Fellow.
This study examines monthly crime rates for ten violent, property, and drug offenses in 34 U.S. cities. Not all cities reported monthly data for each crime. The largest city in the sample is New York, with 8.42 million residents. The smallest is Norfolk, Virginia, with 245,000 residents. The crime data were obtained from the online portals of city police departments. The data are subject to revision, and offense classifications varied somewhat across the cities.
- Homicides rose sharply in 2020, and rates of aggravated assaults and gun assaults increased as well. Homicide rates were 30% higher than in 2019, an historic increase representing 1,268 more deaths in the sample of 34 cities than the year before.
- The magnitude of this increase is deeply troubling, but absolute rates of homicide remain well below historical highs. In 2020, the homicide rate was 11.4 deaths per 100,000 residents in sample cities; 25 years earlier, in 1995, the rate was 19.4 per 100,000 residents.
- Aggravated assault and gun assault rates in 2020 were 6% and 8% higher, respectively, than in 2019. Robbery rates declined by 9%.
- Dometic violence increased significantly during the early months of the pandemic, but these results should be viewed with caution as year-end rates were comparable to year-end rates in 2019, and findings were based on data from just 12 cities.
- Property and drug crime rates, with the exception of motor vehicle theft, fell significantly in 2020. Residential burglary decreased by 24%, nonresidential burglary by 7%, larceny by 16%, and drug offenses by 30%. Motor vehicle theft rose by 13%.
- Homicides increased in nearly all of the 34 cities in the sample. In the authors’ view, urgent action is necessary to address these rapidly rising rates. Subduing the pandemic, increasing confidence in the police and the justice system, and implementing proven anti-violence strategies will be necessary to achieve a durable peace in the nation’s cities.
