According to the latest statistics available from 2023, there are estimated to be only 119,550 World War 2 veterans remaining in the United States [1]. This number represents a significant decline from the 16.1 million Americans who served during the war [1].
It's important to note that this data is specific to the United States. World War 2 was a global conflict, and the number of surviving veterans worldwide would be considerably higher. Unfortunately, there isn't a single source for worldwide veteran population data.
