Demographics of Sniffies and Grindr

I’ve noticed something about the difference between Sniffies ands Grindr in my city. Most of the guys on Sniffies are either black or bottoms looking for bbc. Nothing “wrong” with that of course, but by comparison Grindr is like an Abercrombie and Fitch ad, skewing white, young, and fit. How do the guys on these sites differ where you live?
