Urban segregation replaced regional divides as black urbanization expanded by 1930

Evidence

Black migration from the south coincided with European immigration to cities like New York, Philadelphia, and Chicago. But it was coterminous as well with Chinese, Japanese, and Filipino settlement especially but far from only in San Francisco, and Chicano migration to Southern California and later across the Southwest to join those already long settled as a result of earlier American territorial annexations. As racial interaction consequently began to increase, African Americans, Latinos, and Asians were becoming progressively segregated within cities. The more black urbanization expanded, the more their racial segregation and restriction within cities was extended. Thus by 1930 the spatial location of segregation already had transformed perceptibly from regional to neighborhood divides. — David Theo Goldberg, The Threat of Race, 366
