Variation in the salaries of U.S. and Canadian members of the American Institute of Physics are examined, based on a spring 1985 survey. Graphics highlighting some of the patterns are presented, along with detailed tables and brief summary text. The overall response rate was 65%. Tables cover salaries and geographic location for Ph.D.s salaries and employment type for Ph.D.s, salaries and employment type for bachelor's and master's degrees, salaries and primary work activity, and salaries by sex. These data cover type of employer, type of work, position, and years from degree. Analyses center on median and quartile salaries. The tables also present for comparison the salary means, standard deviations, and median ages of each group. Information on salary changes between 1983 and 1985 is included. The most typical comparisons are cross-sectional, by which the 1985 median salary of industrially employed Ph.D.s are compared to the median salary of similarly employed individuals in 1983. In addition, longitudinal data, which looks at the same people at two or more points in time, provides a better picture of these actual increases. Technical notes are included. (SW)
