The number of black pupils living in traditionally all white suburban Jefferson County neighborhoods has increased significantly since 1974. Data taken from school enrollment information indicate a 63 percent increase in the three years from 1974 to 1977. Increases in housing desegregation in suburban areas are complemented by a slight lessening of segregation in the city of Louisville, due mainly to the decrease of black pupils in the city boundaries. Statistics indicating these trends are presented in table form. The statistics are significant because, under the desegregation plan, attendance areas which become sufficiently desegregated to meet court guidelines can become exempted from transportation for the purpose of desegregation. Factors contributing to housing desegregation are analyzed, and the need for broadening fair housing efforts is stressed. (Author/GC)
