"The racial makeup of the city was 83.90% White, 1.0% African American, 1.0% Native American, 3.30% Asian, 0.5% Pacific Islander, 8.0% from other races, and 2.3% from two or more races. Hispanic or Latino of any race were 13.9% of the population."
That's my city. In my age group (high school) the demographics are much different though, less white, much more Hispanic, and much less of everything else.
Most of my friends are either white or Hispanic, but I have one or two friends that fall outside of that.
I really don't care about race though, I just talk to people I get along with, I'm really indifferent about having a "diverse" friend group as I don't actually care at all.
