Added to the 1,656,000,000 alive in 1900, it seems that 11,457,490,715 people lived during the 20th Century. With only ca. 6 billion still alive in 2000, the century probably saw about 5.5 billion deaths. That means that the 203 million multicides I've counted in the 20th Century would account for 3.7% of all deaths, or 1 out of every 27.

The total of US combat deaths during the Civil War is given as 140,414 -- or some 30,000 higher than most historians would estimate. I suspect (but don't know for sure) that the boost may come from the DoD counting deaths among POWs as combat rather than disease. I can't think of where else they'd get 30,000 more war dead.
How many died of wars in the 20th and 21st centuries? The simple answer is that it is impossible to know. But these totals from my war database may give a hint of the magnitude of the death toll. Please note that these numbers only includes battle-related deaths (see the new faq for definitions) for the whole period. It does not include "excess ...
