What genres of music have the most and least educated fanbases?

[I spent the winter writing songs about getting better]

Most:

-Classical
-Opera
-Emo/Post-Hardcore/Melodic Hardcore (no this is not me just trying to prop up what I like, go check out a Facebook group or forum about this stuff sometime...almost everyone has a college degree.)

Least:

-Post-grunge
-Certain styles of gansta rap (I hardly know anything about this to be more specific, but definitely not the mainstream rap stuff whose fanbase is majority white suburban people.)
-Crust punk

I know a lot of people might think of country, but that's probably close to the national average.
