This report examines the variations in salaries by degree level, employment sector, geographic location, and work activity among members of the scientific labor force and educational system. The data are based on a stratified random sample of one-sixth of the U.S. membership of the American Institute of Physics Member Societies; approximately 14,400 members were queried, and 64% responded. Most of the analyses presented are based on median and quartile salaries. Mean salaries, standard deviations, and median ages are also presented for comparative purposes. Twenty-six tables of data are provided and are divided into the following categories: (1) salaries and geographic location for PhDs; (2) salaries and employment sector for PhDs; (3) salaries for Masters and Bachelors; (4) salaries and primary work activity; (5) PhD salaries for males and females; and (6) salaries and employment sector for PhDs, American Geophysical Union members. Appendixes detail the geographic divisions used in the analysis and provide technical notes. (GLR)
