This analysis is designed to provide Health, Education and Welfare and local school officials with a more objective and uniform assessment of desegregation problems in specific districts in the United States. To carry out the study, Lambda Corporation designed and implemented an analysis procedure for systematically assigning students to schools. The analysis system was designed so that it could produce a wide range of different school assignments, ranging from simple neighborhood attendance zones to plans that provide extensive desegregation in a large metropolitan area. The system allows wide latitude in the specification of ground-rules and goals for an assignment. Once these are specified, the system can provide a systematic assignment that is as efficient as possible in terms of the specified objectives and constraints. Basically three types of publicly available data were required for the study: (1) information on the location and racial composition of the school-age population in each area; (2) information on the location and capacity of the schools in each school district; and, (3) information on the transportation networks in each area, to calculate travel times to assigned schools.
