Credit enrollments at Harford Community College (HCC) are projected for fall semesters 1983 through 1987 by age cohort groups. After introductory material discusses enrollment trends in community colleges in the United States and at HCC, the report indicates that enrollments were projected by determining the ratio of persons enrolled at the college to the number of persons living in the geographic area from which HCC draws its enrollments, and by using the most recent year (fall 1982) as the basis to project future years. Following a discussion of the factors that may affect future enrollments and a summary of findings, the report presents data tables and accompanying commentary providing projections by age cohort groups for the following data elements: total headcount; female and male enrollments; projected 5-year change in enrollment for total, male, and female headcounts; full-time/part-time headcount; credit hours carried; and full-time equivalent (FTE) enrollment. The report projects: (1) an annual increase of 1.0% to 1.5% between 1983 and 1985, followed by no increases in 1986 and 1987; (2) a 5.2% increase in female students and a 4.7% increase in male students by 1987; (3) a 7.5% growth in part-time students and a 1.5% decrease in full-time students by 1987; and (4) a decline in student numbers for the 17-19 and 31-35 age cohorts and an increase among 20-25, 26-30, 36-40 and 41 or over cohorts. Appendices include state census projections and HCC age distributions for fall 1979. (HB)
