Codes and Frequencies
ARMFCC indicates whether a sample adult aged 18 and older (and, prior to 2019, all persons 18 and older) who was ever active duty in the armed forces (ARMFEV), ever served in a foreign country during a time of armed conflict or on humanitarian or peacekeeping mission.
Prior to 2019 there are no comparability problems with ARMFCC. This variable was introduced in 2011.
The NHIS questionnaire was substantially redesigned in 2019 to introduce a different data collection structure and new content. For more information on changes in terminology, universes, and data collection methods beginning in 2019, please see the user note.
