This report sets up the methodology for enrollment estimates and projections, and indicates the general expectation of future enrollments. Estimates for 1969, 1970 and 1971, useful for short-range instructional and budget planning are based on the number of high school graduates and of new students. Projections for 1972 through 1984, useful in long-range facility planning, are based on the number of births and of new students. The experience of the University of Wisconsin and Wisconsin State University campuses for 1964 to 1967 was used as a base for estimates and projections for college transfer and associate degree programs; the experience of the vocational diploma program from 1967 to 1968 was utilized for estimates and projections for that program. Apprenticeship and unclassified enrollments were derived by subtraction of the other programs from the total. Some estimates and projections are: (1) 1970--all programs, 37,755; college transfer, 5,149; associate degree, 12,846; vocational diploma, 12,995; apprenticeship and unclassified; 6,765; (2) 1984--all programs, 49,302; college transfer, 5,807; associate degree, 14,120; vocational diploma, 18,039; apprenticeship and unclassified, 11,336.
