Researcher Adam Lankford, a professor at the University of Alabama, has tracked mass shootings around the world since the 1966 shooting at the University of Texas, when an ex-Marine sharpshooter killed 17 people.

Lankford’s list only includes attacks by public mass shooters, not organizational acts of terrorism or genocide such as the 2008 Mumbai attacks or 2015 Paris attacks.

Only one recent mass shooting — the 2011 attack at a Norwegian summer camp where 69 people died — was more deadly than the incident in Las Vegas.

Another 2017 incident made the list when a gunman killed 26 people at a Texas church. With 17 victims, the Valentine’s Day 2018 Florida school shooting was among the most deadly at schools.
