Not many.
Most of Colorado, New Mexico and Utah are whites and Hispanics.
That's why the crime rates are so low.
The City i live in is less than 1% black.
I am in SLC, UT every time I visit Denver I feel like they just traded the hispanics here, for blacks there. Both places I feel like their cultures are the very stereo typical as well. I feel like utah is more "white" though with our strong mormon back ground, its changing though, Utah always seems to be playing catch up.
Would live either place for sure.
