Definition
This variable indicates whether persons were engaged in active-duty military service in the armed forces of the United States during the World War II era (between September, 1940 and July, 1947 for all samples except the 2003 ACS, which defines the World War II era as December, 1941 through December, 1946). It includes those on active duty in the United States Army, Air Force (which was part of the Army during World War II), Navy, Marine Corps, and Coast Guard during this period, and it excludes those in the National Guard and military Reserves, unless they were called to active duty. Men who served in the Merchant Marine during this period were included in the veteran definition in 1990.
