Segregation shifted from within cities to between cities from the 1950s onward.

Evidence

From about 1950 on, accordingly, segregation across and not just within cities began to increase. By the 1980s this trend had become evident: increasingly members of ethnoracially defined and identified groups, and not only blacks, while living in different neighborhoods from whites tended also and emphatically to live in different cities. Their children now likely attend overwhelmingly segregated schools in different school districts, growing up literally not knowing each other beyond the stilted stereotypical images they glean from television and other audio-visual media. Recent judicial efforts to end the use of racially emphasized means to desegregate public schools across a broad swath of American states are already exacerbating the trends to resegregation. — David Theo Goldberg, The Threat of Race, 379
