This report summarizes findings of a survey of 684 higher education institutions offering graduate programs in the United States; responses were received from 634 institutions. Chapter 1 presents highlights of the survey, including a profile of fall 1997 graduate enrollment for each of four regional graduate school associations (Southern, Midwestern, Northeastern, and Western). Data tables include: type of institution; field of study; gender; citizenship; ethnic group; region; number of applications; and number of graduate degrees awarded. Chapter 2 focuses on trends in graduate enrollment for each of the four regional associations for the period 1986-1997. The data tables that describe year-to-year changes (in the enrollment and degree categories included in the first chapter) include data from the approximately 460 institutions that have consistently responded to the annual enrollment survey. Three appendices present: (1) the survey instrument; (2) a taxonomy of graduate enrollment disciplines; and (3) basic information on the survey, including the methodology, data, reporting, and data availability.
