How Many Living Veterans Served in the Vietnam War?

Of the 19.6 living U.S. veterans alive in 2013, 7 million served during the Vietnam War era. Of those 7 million veterans, nearly 176,000 served during both the Vietnam War and the Korean War, while close to 40,000 served during the Vietnam War, the Korean War and World War II.

A 2013 New York Times article indicated that 75 percent of the 9.2 million Vietnam War era veterans were still alive, a figure consistent with estimates from the U.S. Census bureau. However, the number of living veterans who saw combat action in Vietnam is considerably smaller than 7 million, as only 2.7 million of the 9.2 million total Vietnam-era veterans actually served in the war itself.
