A national survey of 136 member institutions in the 50 states, the District of Columbia, Guam, Puerto Rico, and the Virgin Islands shows fall 1976 enrollment at state and land-grant universities at 3,249,117, or 29 percent of all students enrolled in U.S. higher education. Complete enrollment data, including breakdowns by level of full- and part-time students, enrolled both on campus and in extension programs, are provided. They show that: undergraduate students accounted for 75.4 percent of the enrollment and graduate students, 15.8 percent; there were drops in enrollment at all levels except for first-professional schools when figures for CUNY were included in the comparisons; there were major gains in the enrollment of women; the percentage of students who were part-time increased from 25.1 to 25.9 percent from 1975 to 1976; a supplementary questionnaire showed a decrease of 5.1 percent in the number of extension students; on-campus enrollment for the 98 campuses for which it was possible to compare both extension and on-campus enrollment showed almost exactly the same changes as that reported for total enrollment.
