Minority-student enrollment at colleges and universities increased by 51 percent in the decade ending in 2003, an improvement driven by growth in the number of Hispanic and minority-female students, according to a report scheduled for release today by the American Council on Education. Over all, the number of minority students on American campuses grew by 50.7 percent during the decade, totaling 4.7 million undergraduate and graduate students by 2003. During the same period, the number of white students increased by 3.4 percent, reaching a total of 10.5 million white students in higher education. Although the report notes rising enrollment and degree-attainment numbers for minority students, it says the proportion of African-American and Hispanic students enrolled in college was still not as high as that of white students. Hispanic students accounted for the largest increase in undergraduate enrollment among minority groups, rising nearly 70 percent from 1993 to 2003. By contrast, African-American enrollment increased by 42.7 percent, Asian-American enrollment went up by 43.5 percent, and the number of American Indian students rose by 38.7 percent.
