There are approximately 19 million veterans living in the United States, representing about 6% of the total U.S. adult population. Similar to the U.S. population overall, the veteran population is expected to become more racially and ethnically diverse. And Veterans often have unique medical, behavioral, and social service needs. Health centers offer a hugely important service for Veterans who may not have access to the range of services they require. On a national level, health centers serve nearly 400,000 patients who identify as veterans, a rate steadily increasing over the last five years.
