Do you know what the NATURAL death rate would be for a random sample of the US population consisting of 120,313 over several years around the 1940s? Hint: the PER YEAR figure alone would be around 1862.

The closest to an official figure I have seen is around 5,000 by some Japanese American author and even that is barely credible looking from an actuarial point of view.
Two posters (ANTPogo and myself) have supplied you with what are evidently the official US government statistics for the internment of Japanese Americans during WWII. We even named the same secondary source - given that the moderated thread means we didn't see each other's posts, that is a good recommendation.
The figures broke down properly, whereas your Japanese American author saying 5,000 is you relying on memory w/o providing a source. And yet you don't believe the 5,000 figure for 'actuarial' reasons. Whatever. Your insinuation that there weren't any official figures has been shot down in flames.
Undoubtedly, the majority of the 1862 deaths during internment were among elderly Japanese Americans who may well have died anyway, but some would have died prematurely because of lack of medical care, especially in the early stages when the camp system was being set up.
It doesn't actually absolve the US government of the responsibility for those deaths because they occurred while the internees were under the care of the government. The US government later acknowledged that the internment was an injustice and paid out substantial sums in compensation. (Gee... that sounds familiar!)
What is sauce for the goose is sauce for the gander; historians blame the Soviet and Polish governments for deaths of elderly ethnic Germans during the expulsions from Eastern Europe in 1945, and they blame the Nazi regime for deaths of elderly Jews sent to Theresienstadt, and they blame Stalin for the deaths of elderly kulaks deported to Siberia in 1930, and they blame the British for the deaths of elderly Boers in concentration camps in South Africa during the Boer War, and so on. Because any death in confinement is the responsibility of the one who interned the civilians.
But they're also quite able to notice the differences in death rates between all of these unjust internments. The Japanese American internment camps were not concentration camps. The death rate doesn't rise much above the natural death rate for the US population of that era.
Frankly I'm puzzled because you accept that fact yet still brought up the usual denier talking point of the Japanese American internment camps. Presumably to make the Nazi concentration camps seem better and the US government seem worse.
Unfortunately the moral equivalence backfires on you, because it's widely accepted that the internment of Japanese Americans was unjust, even under wartime conditions and a panic about spies. And the US government paid out large sums in compensation... much like the West German government paid out large sums in compensation to those its predecessor had interned in KZs. Hmmm... maybe paying out compensation is the mark of a rich Western society that can afford to acknowledge historic wrongs and that wants to avoid letting complaints fester.
You'll also notice that American society is not unaware of the internment of Japanese Americans and has also evidently taken some of the lessons to heart, especially regarding civil liberties. The US didn't round up all Arab Americans after 9/11 for mass internment during the 'war' on terror. And contrary to CT blether the FEMA death camps slated for woos and pseudo-patriots don't exist.
