Actually, Chicago is 45% white and 33% black.
Outstanding contribution.
I don't know where everybody gets the idea that 90% of the population of every American city is African American.
It was Archie Bunker who said: "One colored family on the block is a novelty. Two is a ghetto." That was a joke on a sitcom. Toure seems to have bought into it in real life.
[Of course, my joke is, "One white guy on the block is a wigger. Two is gentrification."]
The association of 'black' with 'urban' isn't limited to this Toure person.
