274 days, 294 mass shootings
The United States has gone no more than eight days without a mass shooting this year. On six days in September, there were three or more mass shootings. After Thursday’s attack at an Oregon community college, the total number of deaths by mass shooting this year through Friday is 380, with well over 1,000 injured. The data below is drawn from the Mass Shooting Tracker, which defines these incidents as involving four or more people shot, including the shooter. The tracker draws some criticism because its definition is broader than the FBI’s, which requires three or more people to be killed, not just hurt, by gunfire. But the broader definition is useful because it captures many high-profile instances — like the Lafayette, La., theater shooting in
July, in which two were killed and nine others wounded — that don’t meet the FBI’s criteria.
