What Can We Learn about the Use of Assault-Style Weapons from 50 Years of Mass Shootings?
Building on our baseline study of mass shootings in the US from 1966 to 2006, our new report examines trends in the frequency and lethality of assault-style weapons in those shootings. It finds:
+ Mass shootings have been increasing steadily in frequency since 1950. The use of assault-style weapons, as a proportion of total mass shootings, has remained fairly stable at about 20 percent (figure 1).
+ Assault-style weapons, when used, result in significantly more deaths and injuries than other weapon types (figure 2).
