NOTES: Numbers in italics (1984 to 1987) are not comparable with earlier or later years because only a sample of master's-granting institutions rather than the entire population was included in the survey during these years.
^aThese are the institutional categories used by the Carnegie Foundation for the Advancement of Teaching. See chapter 2, "Characteristics of U.S. Higher Education Institutions," for information on these categories. "Other" institutions are all Carnegie-classified except research and doctorate-granting institutions.
