This report brings together data on salaries of scientists, engineers, and technicians. The salary surveys were conducted by agencies and departments of the federal government, professional scientific and engineering societies, educational associations, magazine publishers, and other professional organizations. Most of the surveys were originally published in 1975-77. Data are reported in 138 tables organized under the following headings: starting salaries, salaries of experienced scientific and technical personnel, salaries of engineers, salaries of engineering technicians and technologists, federal salaries, and academic salaries. Statistical variables include occupation, degree level, sex, years of experience, geographic region, type of employer, and age. The base and time period of each table is noted, and a brief analysis of each group of tables is presented. No attempt has been made to evaluate the reliability of the samples. (BB)
