This report compares the educational attainment and present attitudes of young black adults who did and did not participate in a program that allowed inner-city students to attend suburban schools. The desegregation program, Project Concern in Hartford, Connecticut, began in 1966 by randomly selecting one group of students to be offered the opportunity to attend suburban schools and a second group as controls. Both groups, along with other Project Concern participants, were traced. In 1982, some 700 students and their parents were surveyed, after they had finished secondary school. It was concluded that attending suburban schools reduced high school dropout rates, increased adult contacts with whites socially, and increased the number of blacks choosing to live in interracial housing. Male participants had fewer difficulties with police, perceived less discrimination in colleges and in employment, and were more likely to succeed in college. Female participants were less likely to have a child before age 18. It seems likely that, for a male, the chance of obtaining 2 or more years of college was at least one and one-half times greater if he received a desegregated education. Appendix A discusses data collection methodology, and Appendix B is an analysis of self-selection and response bias. (Contains 12 tables, 7 appendix tables, and 28 references.) (Author/SLD)
