If you find figures that you believe are more accurate that differ from the ones here, please let me know in "comments," and please cite your sources.
Some additional context:
Wars apparently are becoming more and more deadly for civilians. Of the deaths caused by each of the following wars, here are the percentages of those deaths being civilian deaths:
World War I: 14%
World War II: 67%
Wars of the 1980's: 75%
Wars of the 1990's: 90%
Here is the book those statistics are from: WAR AND PUBLIC HEALTH, edited by Barry S. Levy and Victor Sidel, New York: Oxford University Press, 1997.
