In his song 'Terrorist' the artist Lowkey asserts:
When more Vietnam vets kill themselves
After the war than died in it?
Is this true?
Looks like bad data:
Old (1990) data, but estimating 9,000 suicides amongst the Vietnam vets.
Again, old, but with the same number.
While I find the 50,000+ numbers in various places none are high quality. I strongly suspect that the 50,000+ numbers count all military suicides, not merely Vietnam.
