In December 2012, a gunman opened fire at Sandy Hook Elementary School in Newtown, Connecticut. In the wake of what was one of the deadliest mass shootings in American history, we said “never again.” Yet on February 14th, 2019, we are in mourning on the one year anniversary of another school shooting in Parkland, Florida. Former student Nikolas Cruz murdered 17 students and staff members, and injured 17 others at Marjory Stoneman Douglas High School on Valentine’s Day 2018. One year since Parkland and six years since Sandy Hook, we take a look at the mass shootings that have occurred in America since that day in Newtown.

Is the number of mass shootings increasing?

If a mass shooting is defined as an incident where at least four people are killed in a public location, the number of shootings has remained relatively stable. But mass shootings have become deadlier.

The number of mass shootings since 2012 varies depending on how you define a mass shooting. Mother Jones lists 43 mass shootings since 2013, while Vox lists a much larger 1,962. But no matter how you look at it, there have been many mass shootings since Sandy Hook.

The deadliest shootings since Sandy Hook:

1A shooting in the Navy Yard in Washington, D.C., on September 16th, 2013, killed 12, including the killer, 34-year-old Aaron Alexis.
