The United States military maintains a significant number of military personnel in every state. There is at least one military base in every state, and as of September 2023, 2.63 million service members are stationed in the approximately 450-500 bases across the country.
24/7 Wall St. used data from the DOD report Defense Spending By State Fiscal Year 2022 to identify the county in each state with the most military personnel. In each state, we listed the county or county equivalent — such as independent cities, boroughs in Alaska, or parishes in Louisiana — home to the most active duty military troops, excluding reservists, the National Guard, and civilian Defense Department employees.
Troops stationed within the counties or county-equivalents on this list range from fewer than 30 to nearly 85,000. These places typically account for a large proportion of the statewide troop count. Almost every county on this list is home to at least 25% of all active-duty service members within the state. In over a dozen states, a single county accounts for over 80% of all troops.
Why Are We Talking About Military Personnel?
The U.S. military protects its citizens from threats and helps maintain peace and stability at home and worldwide. Military bases contribute to local economies by offering stable jobs, attracting skilled workers, and creating demand for local goods and services.
