This chapter focuses on indicators of postsecondary participation, looking at the characteristics of students who enroll in postsecondary education, students who receive financial aid, and students who receive different levels of postsecondary degrees. Between 1976 and 2004, minority enrollments increased as a percentage of undergraduate enrollments, from 17 to 32 percent. Since 1976, the percentage of female undergraduate enrollments has surpassed that of male undergraduate enrollments. In 2004, the enrollment gender gap was largest for Black undergraduates. Trends in graduate enrollments were similar to those for undergraduate enrollments, with the percentage of enrolled graduate students who were minorities increasing 14 percentage points from 1976 to 2004. As with undergraduate enrollments, female graduate enrollments surpassed male graduate enrollments during this period. Looking at the participation rates of 18- to 24-year-olds in colleges and universities, participation rates of Whites, Blacks, and Hispanics increased between 1980 and 2004 and Black, Hispanic, and White females had higher enrollment rates than their male counterparts in 2004.
