This report provides data on racial/ethnic diversity within the Oregon University System (OUS) in regard to student enrollment, graduation, and retention trends. Five-year total (undergraduate and graduate) enrollment trends within the OUS indicate that representation of students of color increased from 11.5 percent of enrollment in fall 1993 to 12.4 percent of enrollment in fall 1998. Students of color received 8.4 percent of all degrees awarded during 1992-93 and 11 percent of all degrees awarded during 1997-98. Total graduation rates during the period from 1992-93 to 1997-98 increased proportionately for American Indians/Alaskan Natives, Asian/Pacific Americans, European Americans, and Hispanics/Latinos, while those for African Americans remained steady. Six-year retention rates for cohorts of first-time freshmen students who entered OUS institutions in fall 1987 and fall 1992 indicate enhanced persistence among African American, American Indian/Alaskan Native, and European American students. The six-year retention rates for Asian/Pacific American students declined, and the rates for Hispanics/Latinos remained essentially stable. Three appendixes provide statistical data on OUS regular enrollment, degrees awarded, and retention of first-time freshmen by racial/ethnic group. (MDM)
