The deadly shooting at Northern Arizona University this morning was the 47th shooting to take place on a school campus so far this year, according to data collected by gun control advocacy group Everytown for Gun Safety.
Of those shootings, 26 were classified as attacks that resulted in injury or death.
The 21 remaining shootings were a mix of attempted or completed suicides, accidental shootings or instances in which a gun was fired at campus, including grade schools and colleges, but no one was injured.
The statistics show that even though some of this year's individual shootings, like that of Umpqua Community College in Oregon where 10 people died including the shooter, resulted in higher death counts than last year, the total number of shootings is slightly lower than it was at this point in 2014.
Compared to the 47 at this point, there were 50 shootings on school grounds by this time last year, 29 of which were attacks that resulted in injury or death, three more than this year, according to Everytown for Gun Safety data, which is based off news reports.
