2016 Methodology Changes
A note that the data on shootingtracker.com will now comply with the standard Gun Violence Archive methodology on how mass shootings are counted.
Gun Violence Archive has always used the FBI derived definition:
FOUR or more shot and/or killed in a single event [incident], at the same general time and location, not including the shooter.
This difference is that we do not count the shooter among the victims when determining if a shooting reaches the threshold of Mass Shooting. It insures a clear separation between victims of a shooting and those who perpetrate the crime. GVA also does not parse the definition to exclude any type of gun violence such as gang shooting or domestic violence. The definition is purely numerical and reflects ALL shootings which reach that statistical threshold.
