> I was reading the other day that typically mass shootings happen during a recession, and right now is a confusing time because the economy is supposedly doing fantastic, yet we keep having mass shootings. This feels like the sort of thing that's really going to depend on the definition of mass shooting used. Inner city African American gang violence is the majority of "3+ killed by gun at once" incidents, and if your definition includes that then that's what you'll be measuring. And on the other hand if you use "2+ unrelated people killed or injured including shooter, not gang related" like some advocacy groups do you'll get different results, and if you use what most people would consider a mass shooting (3+ unrelated people killed in public place not including shooter excluding gang violence, or "something that shows up on national news") you'll have minimal data to go off of since those events happen <10x/yr.
