In this report, estimates of the total number of positions filled by scientists, engineers, and technicians employed in the U.S. economy in 1999 are presented by industry and by occupational category. For the first time in this annual series, estimates are also presented for mean wages (hourly and annual) of scientists, engineers, and technicians by industry and by occupational category. Summary employment estimates by broad and detailed industry of employment are in tables 14. Employment estimates by detailed occupational classification and by industry are in tables 510. Wage estimates are in tables 1120.
The estimates were developed from the Occupational Employment Statistics (OES) survey, a federal/state program under which national and state estimates of employment, by industry, are generated for nonfarm wage and salary workers. The Bureau of Labor Statistics (BLS) of the U.S. Department of Labor has primary responsibility for developing OES survey procedures and for providing states with technical guidance and assistance with survey problems. State employment security agencies implement the survey at the state level and prepare current and projected employment statistics for these labor markets. Some states also prepare substate estimates. See the Technical Notes for more information about the OES survey.
The Division of Science Resources Statistics of the National Science Foundation (NSF) has enhanced the BLS effort since 1977 by financing the collection of detailed estimates on the kinds of scientific and technical jobs filled, by industry. Analysis of this information yields insights into the dynamics of the labor market. Industries identified in the tables of this report are from the "Numerical List of Short Titles" in the Standard Industrial Classification (SIC) Manual, 1987. The occupational categories are based on the revised Standard Occupational Classification (SOC) System. The 1999 OES survey was the first one to incorporate the revised SOC classification, but the revised SOC was not yet fully integrated at the time of the survey.
Because both the SIC and SOC classification systems have been revised over time, comparisons of 1999 estimates with those published by NSF from previous years of the OES survey should be made with caution. Where possible, former categories were crosswalked to new ones, but often that was not possible. In addition, the scope of the OES survey changed in 1996 from sampling from only about one-third of the economy in each cycle (covering each SIC industry once every 3 years), to sampling from every SIC industry each year.
