Nebraska postsecondary enrollment trends from 1967 to 1987 are examined with focus on population trends, traditional enrollment forecasting, non-traditional enrollment trends, procedure followed in developing enrollment projections, and institutional sector historical and projected fall enrollments. Among the conclusions reached by the study are: (1) Nebraska students go to school in Nebraska--few go out-of-state; (2) population declines are projected for the 18-24-year-old age group; (3) population increases are projected for the 25-59-year old age group; (4) first-time full-time enrollment will decline; (5) total full-time enrollment will decline; (6) part-time enrollment will increase; (7) the net effect will be a moderate decline in total enrollment; (8) moderate reduction in full-time equivalent enrollment may be expected; (9) award-related instruction will decline; and (l0) non-award-related instruction will increase. Graphs of population and enrollment data are provided, along with tables of statistical data on such areas as ratios used in making enrollment projections, estimated population headcount enrollment, and projected numbers of high school graduates.
