b. white flight to the suburbs
Among both white and Black parents, busing children out of their neighborhoods proved an unpopular strategy for achieving integration, although it was primarily whites who resisted the law. When resistance failed to roll back mandatory integration, opponents of busing saw ways around the law. In a momentous decision, Milliken v. Bradley (1974), the Supreme Court confined desegregation remedies to areas within a single metropolitan district.
In places like Detroit, where the Milliken case originated, white middle-class families could now avoid busing by moving to the suburbs. Such white flight contributed to the declining population and tax base of Northern cities during the 1970s and deprived urban schools of funding.
