There are several different subtypes of mass shootings, and school shooters and planned hate-crime shootings each have their own distinct characteristics. They get the most media coverage, for sure, and tend to trend younger than other types, but they're the least common type of mass shooting.

The mass shootings the article is talking about, which are the most common, are often workplace or family shootings, and are usually by middle aged men.

The definition of mass shooting used most commonly now is any shooting with 4 or more casualties, which includes a lot of shootings that most people wouldn't really think of as mass shootings, which are generally thought of as being like the ones like you named.

Right, and I was already aware of several lists of mass shooting using that or similar criteria to determine what fits. It's just a little strange to me to group so many disparate types of events into a list, and then do a study to say "most of these things don't involve mental illness" when most of those events are wildly different from each other.

Definitely agree with you there. The FBI had traditionally treated different types of shootings as each being unrelated. It was US media that pushed the term mass shooting in its current definition (so they could run big-number stories), and the consolidation of very different profiles under one label has done more harm than good, imo.

If you actually break them apart into distinct groups, there is a much stronger correlation with mental illness among especially e.g. school shooters.
