This document presents estimates of graduate enrollment and postdoctoral employment at the beginning of the academic year 1995-96 at all institutions in the United States that granted doctorate or Master's degrees in any science or engineering field. The survey universe is derived from the ongoing National Science Foundation/National Institutes of Health Survey of Graduate Students and Postdoctorates in Science and Engineering; for the fall 1995 it encompassed 722 reporting units at 602 graduate institutions. The response rate was 98.5 percent. Data tables include total enrollment in all institutions of higher education, by level of enrollment and broad field: 1975-95; graduate student enrollments in science, engineering, and health in all institutions, by field: 1975-95; student enrollment by full time and part-time status; and by gender, citizenship status, racial/ethnic background for 1988-95; by source of major support: 1988-95; students in doctorate-granting institutions; students in Master's-granting institutions; science, engineering, and health postdoctoral appointees in doctorate-granting institutions, by field: 1988-95; science, engineering, and health postdoctoral appointees in doctorate-granting institutions, by field; source of support; and number of postdoctoral appointees who were non-U.S. citizens in 1995. Technical notes cover description of survey universe, instruments, and methodology; the response rate; and changes and revisions in data items. (JLS)
