The tragic incident in Boulder was actually the sixteenth mass shooting in the state over the past year and a half — an average of just under one a month. Eleven of them occurred in metro Denver.
This information is culled from the Gun Violence Archive, which tracks violent episodes involving firearms across the country, including Colorado. GVA identifies a mass shooting as an incident in which at least four people are injured or killed; like another major compiler, Mass Shooting Tracker, it places no additional restrictions on what qualifies. Other organizations define the term "mass shooting" differently, as noted in a 2018 RAND Corporation report. For instance, Mother Jones counts only so-called "indiscriminate" incidents with three or more fatalities other than the shooter, and excludes crimes of armed robbery, gang violence or domestic violence. Likewise, Stanford University's Mass Shootings in America database skips shootings related to gangs, drugs or organized crime, but requires just three fatal or non-fatal injuries aside from the shooter.
But those who get hung up on these distinctions are at risk of missing the larger point about the frequency of multi-victim shootings — one which we underscored in an August 2019 post published in the immediate aftermath of mass shootings in El Paso, Texas, and Dayton, Ohio, that took a combined 31 lives. According to the Gun Violence Archive, Colorado suffered 24 mass shootings between the site's 2013 launch and the summer of 2019. That worked out to four per year, or one every three months.
The pace of Colorado mass shootings has nearly tripled since then — and because they're so commonplace, few become dominant media stories. Many readers will have a tough time remembering any of them beyond the King Soopers shooting, despite the elevated number of people hurt or slain. For example, who recalls the July 2020 shooting in Park Hill that killed two people and injured three others? The next month, a shooting in a Denver park left nine people wounded, six of them children.
