CONGRESS OF THE UNITED STATES CONGRESSIONAL BUDGET OFFICE The Cost of Supporting Military Bases NOVEMBER 2019 At a Glance The Department of Defense operates hundreds of military bases and similar installations that host military units and support their daily operations, provid- ing services such as housing, utilities, and grounds maintenance. This report analyzes the relationship between the cost of those services—also referred to as base operations support (BOS)—and specific characteristics of a base, such as its population and physical size. The key findings of the Congressional Budget Office include the following: • BOS costs are strongly related to the number of a base’s employees and its square footage of building space. • With other base characteristics unchanged, BOS costs associated with an increase in population were lower at larger bases than at smaller bases. For example, in 2016 BOS costs increased by $1,000 for each employee added to bases with 25,000 or more employees, but they increased by $14,000 at bases with 5,000 or fewer employees. That finding implies that it would be more cost-effective to expand the population at larger bases than at smaller ones, everything else being equal. • Other characteristics that affect BOS costs at a base are the branch of service that operates it, the mission of the units that it hosts, its location (inside or outside the United States), and its climate, although the effects of those characteristics are not as significant. www.cbo.gov/publication/55849 Contents Summary 1 What Data Did CBO Use to Analyze the Cost of Base Operations Support? 1 What Did CBO Find? 1 What Are Some Limitations of CBO’s Analysis? 1 BOX 1.

The Cost of Supporting Military Bases Summary CBO found that, with other characteristics unchanged, The Department of Defense (DoD) operates hundreds of the increase in BOS costs associated with an increase in bases that support the daily operations of units in the Air population was smaller at larger bases than at smaller Force, Army, Marine Corps, and Navy, providing services bases. For example, the average BOS costs associated such as housing, utilities, and grounds maintenance, with adding an employee at extremely large bases much as might be found in a town or city (see Box 1 (25,000 or more employees) were $1,000; the cor- for a more detailed description of those services). In responding increase in BOS costs at very small bases 2016, $25 billion—about 4 percent of DoD’s budget— (5,000 or fewer employees) was $14,000.
