The neighborhood I grew up in back home in Atlanta was overwhelmingly African-American. Something like 98% black. I later moved to an area where the makeup was something like 85% African American, 14% White, and 1% "other" (divided between Asians and Latinos).
Here in Vancouver, I really got to find out what diversity really means.
Blacks make up only 0.6% of the population here, and I don't think I'd be wrong if I said that Vancouver is mostly a Eurasian city, with large European and Asian (and South Asian) influences.
