Don't you just need a general table of death rates for the 20th century? Such as this for the UK http://1.bp.blogspot.com/--_yGIwe9rks/TpwbBfZB6AI/AAAAAAAAARg/1v4Z78m--po/s1600/UK1901.jpg http://1.bp.blogspot.com/--_yGIwe9rks/TpwbBfZB6AI/AAAAAAAAAR... You can see the pattern you'd expect: a rise in the death rate, compared to the surrounding years, during the world wars. Though there are other peaks, such as the higher peak just before 1920, which is probably influenza, not WWI. edit: Oh, this doesn't show annual death rate by year of birth, which is what you were looking for
