• While DOD employees, including civilians and active-duty service members, are spread across the 50 states, a disproportionate share of defense workers are concentrated in a handful of South Carolina communities.

Headquartered at the Pentagon, the Department of Defense employs nearly 2.6 million people and has an annual budget of more than $870 billion, making it the largest, and one of the best funded agencies in the federal government.

Thousands of DOD employees, including both civilians and active-duty service members, are stationed in each of the 50 states, as well as Washington, D.C. — and while the DOD’s nerve center may be in northern Virginia, one state farther south has emerged as a hub for the U.S. military.

According to Defense Spending by State, a recent report from the DOD, approximately 68,200 national defense personnel were stationed in South Carolina in fiscal 2023 — more than in all but nine other states. The largest share of department employees in the state — 58.1% — are active-duty troops. An additional 16.4% are civilian employees, 15.6% are guards men and women, and 10.0% are reservists. (Here is a look at the states with the most armed forces personnel.)

The largest DOD service branches in the state by total employment, including civilians and reservists, are the Army with about 29,300 employees, followed by the Navy and Marine Corps with a combined total of 23,200 personnel. The Air Force and Space Force also collectively have about 14,200 people in the state on payroll, and another 1,600 South Carolina residents work in other areas of national defense.

Just as South Carolina stands out as a critical state for the U.S. military, there are certain parts of the state where the DOD’s presence is especially concentrated. Due in part to major military installations in the state — including McEntire Joint National Guard Base and Fort Jackson — there are multiple counties in South Carolina that are each home to several thousand Defense Department employees. In one South Carolina county, the DOD has more personnel than 18 entire states. In this single county, the DOD spent over $865.3 million on payroll alone in fiscal 2023. (Here is a look at the newest American military bases.)

These are the seven counties in South Carolina with the most military and civilian Defense Department personnel. All data in this story was compiled by the DOD and is current as of fiscal 2023. Counties for which personnel data was not disclosed were excluded from analysis.

Why it Matters

A significant share of the Pentagon’s budget goes to payroll for the 2.6 million American men and women who work for the national defense. In fiscal 2023 alone, the Department of Defense spent over $167.4 billion on employee salaries and wages. While this money is spread across the 50 states, it has an outsized impact in places that have emerged as hubs for U.S. military operations.
