The relationship between college desegregation and minority enrollments across different educational levels and U.S. regions was investigated. The analysis was based on data from the U.S. Department of Education's 1976 survey of racial and ethnic enrollments at all 3,068 U.S. institutions, focusing on two- and four-year, graduate, and professional levels at public and private institutions. It was found that the South was most segregated at the four-year undergraduate, professional, and graduate levels, while the other regions were more segregated at the two-year level. Even though blacks have gained the highest enrollments relative to whites at the undergraduate levels (especially in two-year programs), the undergraduate level is characterized by more racially segregated schools. This trend of higher segregation where blacks have gained most access and lower segregation where blacks have the least enrollment access also occurs when comparing: segregation at public and private institutions at the same level and region, states within regions, and different levels of higher education in all regions outside the South (and in the South when historically black colleges are disregarded). Data are presented on racial distributions and a segregation index (a measure of racial separation of enrollments standardized for the number of available blacks and whites). The organization of higher education, as compared to elementary-secondary education, appears to produce either a low enrollment ratio of blacks or a high degree of racial separation. (SW)
