After the rampage Thursday at Oregon’s Umpqua Community College, statistics began flying, including the claim that there now have been 45 school shootings this year.
That’s the tally by the gun control group Everytown for Gun Safety, which is careful to verify each instance.
But it’s also a broad definition — a firearm discharged on school property — and doesn’t include three other shootings that turned up in an Internet search and involved a school bus and school traffic zones.
The toll from the Everytown list plus the three additional incidents is grim: 16 killed, including seven suicides, and 37 others injured.
Never miss a local story.
Thursday’s shootings in Oregon left 10 more dead and seven more injured.
The youngest non-suicide fatality was a 16-year-old high school student. At colleges, three students, two professors and a university staff member were killed. Two young men were killed on elementary school playgrounds or parking lots.
No elementary school students were among the gun deaths this year, though one girl at an elementary school was injured when a classmate brought a gun to school and it went off.
But until the mass shooting Thursday, none of the deaths this year resulted from someone opening fire in a classroom, cafeteria or dormitory.
Two of the shootings could have ended up worse had the shooter not quickly been tackled — one in which a principal was wounded, and another in which the only two shots the student hit the ceiling. In that incident and 12 other gun discharges, no one was struck by the bullets.
To be sure, there are different lists with different definitions and tallies. Recent fact checks conducted by media outlets including The Washington Post have found there is no standard way to count what constitutes a school shooting.
A report by The New York Times also found that some studies include stabbings, shootings that happen near but not on school grounds, and accidental discharge of weapons.
But the Everytown list, plus the three other instances that didn’t meet its definition, did involve firearms and school property and could be verified by local news accounts.
Our list includes 29 school shootings in 2015 in which someone was injured or killed on school property or on school buses, omitting the suicides except for one that was part of a murder-suicide.
