[219] Mass Shootings in the USA

I am recording every mass shooting in the US, starting 01 Jan 2019 on an ongoing basis, using daily data from the Gun Violence Archive.

Their definition of a mass shooting is firearm violence resulting in at least four people being shot at roughly the same time and location, excluding the perpetrator.

I draw one box for each shooting, showing date, location and casualties.
+ = killed
O = injured
