Iowa Casualties & Dead

I have seen multiple figures for the number of Iowans who died in WWII. These figures vary substantially, from 7,046 to 8,398 for military members only and none include a source. In truth we will never have an exact count, but my current estimate of Iowa deaths, including civilians (merchant mariners were civilians), would be around 7,800, with around 7,600 for military deaths along.

The number of Iowa casualties would be far higher, as it would include casualties who survived, namely:

wounded and injured in action who recovered,
prisoners of war who were released,
missing who were found alive.

Casualties do not include non-battle deaths, which for the first time, in WWII, were less than casualty-related deaths.

In WWII, the War and Navy Departments had different systems for recording casualties and deaths. This is illustrated in the War Department's dead list and the incomplete Navy Department's casualty list for the state of Iowa, both released in 1946.
