The science and engineering (S&E) labor force helps to create and advance our scientific and technological knowledge, transform these advances into goods and services, and fuel America's economy, security, and quality of life. This report details several aspects of the U.S. S&E workforce, including growth, demographic makeup, earnings, and unemployment. Nearly 7 million individuals work in S&E jobs, and almost 25 million hold an S&E bachelor's degree or higher. In addition, over 17 million people constitute the skilled technical workforce--individuals who use S&E skills in their job but do not have a bachelor's degree.
