This is interesting... or is it? (The brown and beige categories are cringe-inducing, but overall it's a good conversation-starter, and a good inoculation against maps showing every part of the world as tied to one religion only.) It's from a 2016 article in National Geographic (online only) called "The World's Newest Major Religion: No Religion." I'll be using it in class tomorrow, to contextualize - and provincialize - the US-focused stories on the "rise of the religious 'nones'."
