Harlem IS a neighborhood; it does not have any neighborhoods of its own.

Harlem is actually two neighborhoods, really: West Harlem and East Harlem. West Harlem is traditionally and historically a black neighborhood, while East Harlem (also known as Spanish Harlem) is a primarily Latino neighborhood.

In recent years, West Harlem has become increasingly gentrified. An influx of middle-class and JetBlack upper middle-class white people has turned West Harlem into a much more expensive neighborhood than it used to be.

East Harlem, on the other hand, remains woefully impoverished.
