Only in some areas. I grew up in one of those flyover states, according to wikipedia the demographics of my town were 97% white while I was a teenager (~94% white now).

I much prefer being in more diverse areas, but I don't think where I grew up was somehow bad or wrong. It is a very middle class place, so it's not like the minorities were being pushed out, there just weren't many non-white people that wanted/want to live there! ...but to be fair, a lot of white people don't want to live there either, it's quite boring.
