UCLA also became known for the ethnic diversity of its student body during Young's tenure. The year before Young took office, the percentage of minority students at UCLA was estimated at 12%. The year after he retired, the percentage of minority students was 54%. Young was a vocal supporter of affirmative action, the development and recruitment of minority faculty, and the establishment of ethnic studies centers for African American, Chicano, Asian American and American Indian cultures. In 1978, he announced a joint program with Charles R. Drew University of Medicine and Science to train physicians to work in the inner city.
