In August 1972, Kirkwood Community College began a research project to: (1) ascertain population and enrollment trends by various age groups for each of Iowa's 15 school areas and for the State as a whole; (2) ascertain potential enrollment by categories of students; (3) develop awareness of the relation of population and enrollment changes to manpower needs, student interests, facility needs, and program offerings; (4) ascertain trends for post high school education and their relation to school enrollments; and (5) provide a basis for annual or biennial updating of enrollment projections for area schools. Data sources were the Iowa Department of Health, United States government documents, the Iowa Department of Public Instruction, and others. The compiled data pertinent to each area's K-12 enrollment patterns were discussed with area administrators. Additional data were collected from students in each area school in the arts and sciences and in vocational-technical education. The report reflects a synthesis compiled in September 1973 and revised in February 1975. Collection instruments and bibliography are appended. (Author/MF)
