On March 15, NPR noted the heinous nature of Florida’s Parkland school shooting but quickly added that claims school shootings are at epidemic levels are false.
NPR’s observation is drawn from the work of Northeastern University’s James Alan Fox, who demonstrates that there were more “multiple victim” school shootings during the 1990’s than now.
According to NPR, Fox shows that “in the 1992-93 school year, about 0.55 students per million were shot and killed; in 2014-15, that rate was closer to 0.15 per million.”
