Goths

This study found a higher suicide and self-mutilation rate among teens belonging to the "gothic" subculture. But you didn't need this study to confirm your already morbid stereotypes. Also, remember that just because there is a higher incidence among this group, does not imply that all goths mutilate or kill themselves.

Their definition of goth (albeit quite hilarious):

Goth is a subgenre of punk culture characterized by "a dark and sinister aesthetic, with aficionados conspicuous by their range of distinctive clothing and makeup and tastes in music,"

Yeah, somehow aficionados has the wrong connotation for this context.
