ARMFTIM4 indicates whether an individual aged 48-101, who has ever served in the U.S. Armed Forces, was active-duty in May 1975 to August 1980.

Active duty does not include training for the Reserves or National Guard, but does include activation for service in the U.S. or in a foreign country, in support of military or humanitarian operations. The value of the final annual person weight (WTFA) for active duty military personnel is zero, so they are not included in national (i.e., weighted) estimates.


There are no comparability problems with ARMFTIM4. This variable was introduced in 2011.
