"Across the U.S., nearly 24 million people—a little over 15% of the workforce—are involved in military, public, and national service at the local, state and federal levels. Of this number, approximately 16 million are employed in state and local governments. The federal government numbers include active duty military personnel and U.S. Postal Service workers. The U.S. military has about 1.4 million active duty service members and another 800,000 reserve forces. There are approximately 800,000 postal workers. Beyond the military and the postal service, 2 million people—just over 1% of the U.S. workforce or 0.6% of the total population—are permanently employed by the federal government. More than 70% of the federal workforce serves in defense and security agencies like the Department of Defense, the intelligence community agencies, and NASA.

Contrary to popular belief in the bloated growth of the U.S. public sector, the size of the federal government proportionate to the total U.S. population has significantly decreased over the last 50 years. It has also shrunk in absolute numbers in terms of both the full-time and part-time workforce. If we compare the size of the U.S. public sector as a percentage of the total workforce with other advanced countries, the U.S. is often smaller than its European counterparts, including the United Kingdom, although larger than Japan, which has one of the smallest public sectors internationally. In stark contrast, 40% of the workforce in Russia is employed in the public sector. In Europe, the optimal size of government is equally hotly debated, while in Russia, the size of the government and the dependency that this generates within the workforce tends to mute critical commentary." https://www.brookings.edu/policy2020/votervital/public-servi...
