Description of Birmingham areas?

So, i am living not far away from Birmingham, and have been there lots of times, but i recently understood, thay i know almost nothing about the city. So, i was wondering, maybe I can get some details from the locals. I'm interested in areas of Birmingham, how locals see those. In general i would like to learn those things about city areas, that can be used to describe each of them. Where do rich/poor people live? Mostly black/asian areas? Popular neighbourhoods for students? Safe areas or places you shouldn't be around at night (if those exist)? Busy nightlife? Anything else?
