Neo-segregation is the voluntary racial segregation of students, aided by college institutions, into racially exclusive housing and common spaces, orientation and commencement ceremonies, student associations, scholarships, and classes. This study of racial segregation at Yale University is part of a larger project examining neo-segregation in American higher education in the period 1964-2019. During those fifty-five years, many American colleges and universities that initially sought to achieve racial integration found themselves inadvertently on a path to a new form of racial segregation.
