Trends in enrollments and degrees for physics and astronomy students are examined, based on results of the American Institute of Physics' annual Survey of Enrollments and Degrees. Information is included on: changes in the number of institutions that grant physics degrees, physics degrees awarded by academic year, 1971-1982; undergraduate and graduate enrollments and degrees by institution type, 1971-1983; introductory physics enrollments in physics-degree-granting institutions by geographic region, 1978-1983; introductory physics enrollments, 1982-1983; undergraduate physics majors by geographic region and type of institution, 1982-1983; full- and part-time graduate enrollment by type of institution, 1973-1983; trends in U.S. and foreign graduate physics students, 1973-1983; unfilled assistantships for first-year graduate physics students, September 1982; number of physics degrees granted by sex and minority group status, 1981-1982; and trends in astronomy enrollment and degrees, 1975-1983. The data indicate that with the exception of doctorates, the numbers of 1981-1982 physics degrees conferred increased. Introductory astronomy courses attract large numbers of students, although the number of astronomy majors is small. (SW)
