This paper documents trends in school segregation in different geographical regions throughout the United States between 1968 and 1976. The avarage level of school segregation between whites and minorities (Asian, Hispanic, and Native Americans) declined from a level of 42 to 21 points (on a scale of 0 to 100). Most of this reduction was due to the implementation of school desegregation programs directed against the separation of black and white pupils. The decline was more pronounced in the South, in small districts, in districts located in nonmetropolitan areas, and districts that desegregated under court directives. Although the majority of pupils in 1976 were concentrated in districts that had implemented some form of desegregation program, the average minority student was still attending school in districts with segregation levels exceeding 40 points, due primarily to their concentration in large districts.
