This report describes postgraduate enrollment trends for ethnic groups underrepresented at University of California, Davis. The UC Davis Student Affirmative Action (SAA) Plan identifies the following groups as underrepresented in both the Graduate Division and professional schools: American Indian, Black/African-American, Chicano/Mexican American, Filipino/Pilipino, and Latino/Spanish-American. The report refers to this group collectively as SAA students. The Plan also designates Asian students to be underrepresented in certain graduate fields as well as in Management and Veterinary Medicine. The number of students from underrepresented ethnic groups applying to and enrolling in the UC Davis Graduate Division increased dramatically between 1981 and 1988, resulting in a doubling of the proportion of SAA students. Applications to UC Davis professional schools of Management, Law, Medicine, and Veterinary Medicine declined overall from 1981 to 1988; the number of SAA applicants declined by a smaller amount, while total enrollment of SAA students increased. The proportion of SAA students enrolled in the UC Davis professional schools (12%) now equals the proportion in which they receive baccalaureate degrees in the state of California. SAA students are less well represented in the Graduate Division (7%), but disparity between baccalaureate degrees received and graduate enrollment has narrowed considerably. The disparity between proportions of Asian students receiving baccalaureate degrees (11%) and enrolling in UC Davis professional schools (10%) has been reduced but continues. (JDD)
