List of mass shootings in the United States in 2019
From Wikipedia, the free encyclopedia
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.[2][3]
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.[4] 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.[5] 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.[6][7] The crowdsourced Mass Shooting Tracker project has the most expansive definition, of four or more shot in any incident, including the perpetrator.[8]
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.
