This report documents long-term trends in racial/ethnic enrollment in higher education and presents enrollment data for the fall of 1988. The first section presents overall enrollment trends for institutions of higher education by racial/ethnic categories and selected student and institutional characteristics, such as sex, level of study, type of institution, and control of institution. The data for 1978 through 1984 come from the Higher Education General Information System (HEGIS) fall enrollment survey; the data for 1986 and 1988 are based on the Integrated Postsecondary Education Data System (IPEDS) fall enrollment survey. The second section presents household-based statistics from the Current Population Survey. The information is used to derive a measure of college participation rates for 18- to 24-year-olds and 25- to 34-year-olds. The report also includes a technical appendix and a glossary. (JDD)
