Mass shootings are defined by the number of those that are killed and injured. Find out which were the worst mass shootings of 2018 and the deadliest so far in 2019.

In the wake of the Sandy Hook shooting in 2012, Congress redefined “mass killings” as “three or more killings in a single incident.” Prior to Sandy Hook, the Federal Bureau of Investigation (FBI) defined a mass murderer as someone who “kills four or more people in a single incident,” excluding the perpetrator.

Though there is no clear legal definition for the term “mass shooting,” the incidents have occurred at consistently high rates for decades. Mass shootings are now occurring nearly every day in the U.S., documenting gun violence statistics has become a priority for governments and law enforcement across the nation. 

The following overview outlines the most violent and often deadliest mass shootings from 2018, by defining a mass shooting as four or more people being shot or injured by gunfire in a single incident.
