One in a series on southwestern states, this report deals with the underrepresentation of Hispanics and other racial and ethnic minorities in higher education and provides specific information concerning Arizona's population. Written for educational policy makers, the report focuses on the implications of the fact that the greatest population growth in the next 20 years will take place among minority populations, whose rates of postsecondary educational attainment and socioeconomic status have been historically low. Information is presented in graphic and narrative form for 10 specific areas related to population growth, educational attainment, and family income. Exhibit 1 is concerned with population growth from 1960 to 1980 and projections for 2000. Exhibits 2 and 3 look at population by racial and ethnic origin. Exhibits 4 and 5 examine the educational attainment of persons aged 25 and over and the persistence of White, Hispanic, Black, and American Indian high school students. Exhibits 6 and 7 illustrate the relationships among race and/or ethnicity, family income, and college attendance. Exhibit 8 displays the composition of postsecondary enrollments by race and ethnicity compared with each group's representation in the college-age population. Exhibits 9 and 10 show postsecondary degrees earned by race/ethnic group. (JHZ)
