There are a number of reasons for what you observe. (1.) Early immigrants naturally seek out others-like-self (comfort, familiarity, etc). (2.) A high percentage of early immigrants, unless in college or university, fall within the lower socio-economic strata. They move to areas that they can afford in order to satisfy those primary needs. (3.) As they become more solvent they move into more middle-class neighborhoods. (4.) As their children become more acculturated, they move into more middle-class neighborhoods. (5.) Whereas many immigrants. from diverse cultures, enter the U.S. at a zero or negative 3 on the Emotional Perception scale, African Americans (as a group) sit at -8. There is less emotional willingness, within the larger “power” population, to allow African Americans the freedom of integration. There are many reasons for this – not to be discussed here. However, this is clearly evidenced where one Black with a foreign accent is afforded greater freedom of engagement, even after controlling for education, than an American Black. …or when a lighter-skin Latino or Black is still perceived as “safer” and hence more able to negotiate and navigate a variety of cultural environments. It is truly not just this one.
