Implications of the demographic transformation of Arizona for the future of higher education in the state are examined. Since the changing size and character of the minority population figure prominently on the demographic changes, the major focus will be on changes in the minority population and the effect on future minority participation in higher education. Three major demographic characteristics of the state's population are examined: size and distribution, age, and sex. Data are presented for the entire state and, in some instances, its 14 counties. Characteristics of the following racial/ethnic groups are addressed: White, Black, American Indian/Eskimo/Aleut, Asian and Pacific Islander, and Spanish origin. In addition, the number of youths and adults who are limited or non-English speaking is examined by county. Attention is also directed to minority participation in Arizona's high schools, community colleges, and senior postsecondary institutions. After examining minority participation in each of the 15 public community colleges, the three senior institutions are reviewed individually. Framing responses to the changing demographics and monitoring minority participation and success is considered briefly. (SW)
