Utilizing certain guidelines and assumptions, this report presents actual, estimated, and projected enrollment for Oregon's 38 institutions of higher education between 1959 and 1978. The report is composed mostly of statistical tables presenting data on the 12 community colleges, 9 public 4-year institutions, and 17 private and independent institutions. Seminaries and Bible schools are not included. It is noted that total enrollments are expected to increase by 55% between 1968 and 1978, after an actual increase of 170% between 1959 and 1968. Between 1968 and 1973, the proportion of enrollments in community colleges will increase, while the proportion in public 4-year and independent and private instructions will decline. Between 1973 and 1978, the relative proportions will remain stable. (DS)
