Homicide rates in large U.S. cities jumped by more than 30 percent in 2020, on average, and those rates have climbed another 24 percent this year, according to preliminary data from criminologists.

So, what’s behind the spike in violent crime in the United States?

Tom Clark is a professor of political science and the co-director of the Politics of Policing Lab at Emory University. Clark says that, while there aren’t definitive answers on why crime rises or falls, the continuing increase seems linked to the economic hardships and frustration caused by the pandemic.
