This report reviews housing, land use, employment, and transportation practices in the Boston metropolitan area as they impinge upon the opportunities of minority group persons in the inner city. It focuses upon the newer suburbs, particularly those where housing and industrial parks have been developed since the construction of Route 128. The report details the extent of racial exclusion in Boston suburbs and examines the policies and practices of Federal, State and local government, and those of private employers, the housing industry, and private citizens. The first three chapters provide general background information on the suburbs, the black minority in the city of Boston, and suburban development in the Boston area. The remainder of the report consists primarily of data presented at hearings held in the city of Boston and in two groups of suburbs in 1970. Testimony at the hearings in Boston, Needham, and Marlborough, June 1-4, 1970, was provided by public officials of the local communities, organizations, private citizens, representatives of the State government, and professionals in fields related to metropolitan growth. The final sections of the report describe some of the relationships between State and Federal agencies and suburban development, and offer recommendations for change. (Author/JM)
