This report presents national estimates of employment of scientists, engineers, and technicians (SETs) in manufacturing industries in 1983. The estimates are provided as data in five charts and three detailed statistical tables. Data in charts include: SETs by sector of employment; employment growth in high-technology and other manufacturing industries (1980-83); scientific and technical personnel by selected manufacturing industry; employment of SETs in manufacturing industries by occupational groups; and SETs in manufacturing industries. Tabular data include: SETs in manufacturing industries by major occupational group and detailed industry of employment; SETs in manufacturing industries by detailed occupation and broad industry of employment; and SETs in each manufacturing industry as a percent of total employment in the industry, and the relative error. Analysis of these data, which come from the Occupational Employment Statistics survey and are in Standard Industrial Classification codes 20 through 39, provides information into the dynamics of the labor market as demand for SETs responds to variations in growth among industries, and to the impact of technology and other factors, upon industry. One finding is that three industries (electrical and nonelectrical machinery, and transportation equipment) employed the bulk of engineers and technicians, while scientists were concentrated in the chemicals industry.
