List of mass shootings in the United States in 2019


This is a list of mass shootings in the United States that have occurred in 2019. Mass shootings are incidents involving multiple victims of firearm-related violence. The precise inclusion criteria are disputed, and there is no broadly accepted definition.Gun Violence Archive, a nonprofit research group that tracks shootings and their characteristics in the United States, defines a mass shooting as an incident in which four or more people, excluding the perpetrator(s), are shot in one location at roughly the same time. The Congressional Research Service narrows that definition, limiting it to "public mass shootings," defined by four or more victims killed, excluding any victims who survive. The Washington Post and Mother Jones use similar definitions, with the latter acknowledging that their definition "is a conservative measure of the problem," as many shootings with fewer fatalities occur. The crowdsourced Mass Shooting Tracker project has the most expansive definition, of four or more shot in any incident, including the perpetrator.There were 434 mass shootings in 2019 that fit the inclusion criteria of this article, resulting in 517 deaths and 1,643 injuries, for a total of 2,160 victims. Compared to the previous year, there were 111 more incidents.
