Notes:
Author's Note - Perhaps no other group of statistics lends itself to such differences among sources than casualties. Suffice to say that differences may amount to the millions making it impossible to present figures which are universally accepted, for example, Soviet civilian dead vary from as low as 6 million up to 24 million. Some figures include famine casualties and other indirectly-related causes. The figures listed here are an attempt to find the most accepted numbers (the medians, rather than the means), reflecting the direct cost of the war incurred by the participants.
(1) Official government figures are given when available.
(2) China military dead Nationalist only (Communist aprox. 500,000 dead).
(3) United Kingdom civilian dead include merchant marines (30,248 dead).
(4) United States military dead include all causes (291,577 official battle dead).
