Forecasts of fall headcount enrollment for 1980-90 for higher education institutions in Texas are presented. These revised forecasts are based on a combination of projected population for the state and historical college attendance patterns. Two additional years of official county population estimates and actual college enrollments were used, and more precise procedures for determining the expected net migration change and age distribution of the population in each county were incorporated. In addition, participation rates from individual counties were determined for each of the four age groups, replacing the average statewide rate previously used to forecast public senior college enrollment. Annual enrollment forecasts are presented for the five groups of institutions: public and independent junior/community colleges, public and independent senior colleges, and the Texas State Technical Institute. These forecasts are the aggregate enrollment for all institutions in each group; enrollment forecasts for individual institutions were prepared only for the 37 public senior colleges and universities. Participation rates by age groups in public senior colleges for the state as a whole and for five large counties are presented. Information is also presented on junior/community college enrollment by selected age groups for 1975-79 and on projected fall headcount enrollments for 1980-90 by selected age groups. After public senior college enrollment had been forecast, a regression equation was established to predict the total independent senior college enrollment. (SW)
