Since the end of World War II in 1945, approximately 7,057,000 U.S. veterans have died. This figure, derived from VA Veteran Population Projection Models (VetPop) and National Death Index linkages, reflects the natural aging of successive veteran cohorts rather than combat losses alone.
| Cohort | Service Period | Current Status | Mortality Drivers |
|---|---|---|---|
| World War II | 1941-1945 | Median age at death: 85+; <90% deceased | Natural aging, cardiovascular, cancer, neurodegenerative |
| Korean War | 1950-1953 | Median age: 85-90; rapidly declining | Age-related chronic disease |
| Vietnam Era | 1964-1975 | Peak mortality years (70s-80s) NOW | Chronic disease, Agent Orange presumptives, suicide (elevated vs. civilian) |
| Gulf War | 1990-1991 | Age 50s-60s; early mortality phase | Gulf War Illness, cardiovascular, cancer |
| Post-9/11 (OEF/OIF/OND) | 2001-present | Younger cohort (30s-50s) | Suicide (leading), accidents, emerging chronic conditions |
| Peacetime Service | All eras | Broad age range | Mirrors general population + service-connected conditions |
These aren't just statistics. Each number represents a life of service. The accelerating mortality of the "Greatest Generation" and Korean War veterans underscores a narrowing window to honor, document, and learn from their experiences—while preparing systems for the Vietnam and post-9/11 cohorts following behind.
