A study was conducted to compare the College of Marin's (CM's) ethnic profile for fall 1979 credit students and for full-time tenured or tenure track faculty employed in spring 1980 with local, regional, and state census data for 1980. The number and percentage of Blacks, Hispanics, Asian-Pacific Islanders, and Native Americans were tabulated for the college as a whole and for six academic departments (i.e., physical education, vocational education, social science, natural science, humanities, and instructional/student services). In addition, the student population at CM was contrasted with state and Bay Area patterns of student enrollment. Study findings included the following: (1) Black faculty accounted for 3.14% of the instructors at CM, compared to a 2.46% Black representation in Marin County, a 9.01% distribution in the Bay area, and a 6.35% representation in the state; (2) Hispanic faculty accounted for 1.89% and Asian-Pacific Islanders 3.14% of the college total; (3) there were no Native American faculty members at CM, although the county representation was 0.35%, Bay Area 0.63%, and state 0.7%; (4) of the students at CM, 2.8% were Black, 3.2% were Hispanic, 3.2% were Asian-Pacific Islander, and 0.9% were Native American; (5) within Marin County, 2.46% of the population was Black, 4.14% Hispanic, 2.44% Asian-Pacific Islander, and 0.35% Native American. The study report includes a literature review and a discussion of the implications of the findings for affirmative action at CM. (HB)
