This report provides information on science and engineering degrees conferred in the aggregate United States over the period 1966-1994. It is based on data obtained from several Federal agencies. The data was acquired as part of these agencies' general statistics programs. The Bachelor's and Master's degree data were obtained from universe institution surveys of the National Center for Education Statistics while data on doctorates are from the Survey of Earned Doctorates, and a universe survey of individual doctorate recipients collected by the National Research Council. Degree data are compiled for a 12-month period. Included in the report are the current classification schemes for the Integrated Postsecondary Education Data System (IPEDS) completions survey and the survey of earned doctorates and historical changes in the IPEDS/Higher Education General Information Service (HEGIS) classification system. Data are classified by total number of degrees, gender, major field, and age. (JRH)
