The United States has a mass shooting problem. While it only has 5% of the world's population, 31% of public mass shootings occur in the US. The purpose of this map isn't to suggest a cause of or a solution to gun violence in the US, but to show the extent of the problem graphically. While the worst incidents can make national headlines for days, the majority of mass shootings aren't reported beyond the local news.
This map was created using data from the Gun Violence Archive (GVA), an independent not-for-profit corporation that collects data on gun violence. GVA defines a mass shooting as "Four or more shot and/or killed in a single event, at the same general time and location not including the shooter".
Each incident on the map has a link to more details at GVA and a media source of the event.View Map
