You would, perhaps, prefer Bantu-Chicagoan? The "nomenclature" has shifted over time, and (IMHO) has a lot more to do with notions of political correctness than any preferences of the individuals concerned. At this instant in time, it is African-American, although I'm not entirely sure about the hyphen. "Black people" is used by those who don't keep up, even though it isn't particularly descriptive, but I don't think "the blacks" has been in common use since about 1864.
