“Our analysis is based on data from The Violence Project, a nonprofit research group that uses a narrow definition of mass shootings adopted from the Congressional Research Service, which advises federal lawmakers.
Thirty-one of these massacres occurred from 2017 through 2021, compared with 24 from 2012 through 2016, according to The Violence Project data. We compared five-year periods so we could measure trends over time, rather than focus on the dip to two incidents in 2020, which researchers attributed to the COVID-19 lockdown, or the spike caused by the 2017 mass shooting in Las Vegas that left 58 dead. The last five years have seen more mass shootings than any other comparable time span dating back to 1966.”
