Demographic Diversity of the Science, Technology, Engineering, and Mathematics (STEM) Workforce in the U.S. Department of Defense

How do salary and benefits for science, technology, engineering, and mathematics (STEM) workers in the federal government compare with those for private-sector STEM workers? Using a labor market analytic approach, the authors describe STEM workers in the two sectors, note differences from non-STEM counterparts, compare STEM salary and benefits, and make recommendations to improve data collection and evaluation for STEM hiring and retention.
In a companion report to the 2019 National Defense Authorization Act, the U.S. Senate Committee on Armed Services directed the Department of Defense, in consultation with the Office of Personnel Management and the Department of Energy, to conduct a comparison of salary and benefits for government professional engineers and scientists with those for workers in similar positions in the private sector. Asked to undertake this analysis, RAND researchers interpreted "engineers and scientists" as the science, technology, engineering, and mathematics (STEM) workforces in the public (federal civilian) and private sectors.
The authors compiled and analyzed workforce data from U.S. government sources and available literature to describe and compare trends in private- and public-sector STEM employment levels, unemployment rates, work hours, salary, and benefits. Where data were available, they also conducted subgroup analyses of these trends based on demographics, education levels, occupational categories, and geographic regions. In this report, the authors examine why STEM workers are of special interest to national defense and the civilian economy. They describe and compare the characteristics, employment trends, and pay levels of the private- and public-sector STEM workforces to their non-STEM counterparts. The report concludes with a discussion of how compensation is but one component of hiring and retaining qualified workers in the federal government and presents a set of policy and research recommendations.
