U.S. mass shooters are almost all men

As we saw this week in Sutherland Springs, Texas, the victims of mass shootings come from all ages, races, genders and creeds. As was also the case in Texas, the perpetrators are, with very few exceptions, men — mass shooters are about 50 times more likely to be male than female.

The data: Just two of the 129 lone shooters who killed at least 4 people since 1966 were female, per data compiled by the Washington Post. In a third case, the San Bernardino attack in 2015, there was one male and one female shooter. Overall, 98% of the mass shooters are men, compared to 89% of those arrested for murder, per FBI data.
