　　To find the worst mass shootings in the U.S. last year, 24/7 Wall St. reviewed Mother Jones’ Mass Shootings study. Since 2013, Mother Jones has classified a mass shooting as a single attack in a public place in which three or more people were killed, not including the perpetrator. All other information came from the database. Incidents are the total number of fatalities from each event. We added supplemental information including the date, location, weapon types, and total victims. (School shootings include any incident involving a firearm at school, at any time.)

　　The most violent U.S. mass shooting last year, by any definition, was the Robb Elementary school massacre in Uvalde, Texas, which claimed the lives of 19 children and two teachers before the 18-year-old shooter was gunned down by police. Seventeen others were injured in that attack.

　　Two other U.S. mass shootings last year involved at least 30 casualties: the July 4 Highland Park parade shooting in Illinois in which seven people were murdered and 53 others were injured, and the Club Q gay nightclub shooting in Colorado Springs, in which five people were killed and 30 injured.

　　The Mother Jones research purposefully narrows the definition of mass shootings in an effort to filter out certain types of gun crime, such as gang-related or domestic violence.

　　“Gang shootings at nightclubs or house parties are a problem,” the magazine’s national affairs editor Mark Follman wrote in 2015. “Ditto abusive men gunning down their families in their own homes - a problem that occurs far more frequently than is generally understood. … But while also important, these are distinct issues that require different analysis and solutions.” (Here are ntent=the-most-common-gun-related-crimes-in-each-state&wsrlui=811944072">the most common gun-related crimes in each state.)
