This survey, 24th in an annual series, provides nationwide salary data for 24 occupations spanning 101 work level categories. This information was collected from establishments in all areas of the United States except Alaska and Hawaii. The following major industrial groups were surveyed: mining; construction; manufacturing; transportation; communications, electric, gas, and sanitary services; wholesale trade; retail trade; finance, insurance, and real estate; and selected services. The minimum size of the establishments surveyed was either 50, 100, or 250 employees, depending on the industry. The approximately 44,000 establishments within the scope of the survey employed slightly more than 22 million workers; just over 45 percent were professional, administrative, technical, and clerical employees. The survey presents separate occupational data for metropolitan areas and for establishments employing 2,500 workers or more. Other information contained in the data includes changes in salary levels, employment statistics, average salaries, salary distributions, pay differences by industry, and average standard weeky hours. Appendixes to the document describe the scope and method of the survey, validate the job matches, define occupations, and compare salaries in private industries with salaries of Federal employees under the General Schedule.
