Civilian casualty ratio
Some 7 million combatants on both sides are estimated to have died during World War I, along with an estimated 10 million non-combatants, including 6.6 million civilians. The civilian casualty ratio in this estimate would be about 59%. Boris Urlanis notes a lack of data on civilian losses in the Ottoman Empire, but estimates 8.6 million military killed and dead and 6 million civilians killed and dead in the other warring countries. The civilian casualty ratio in this estimate would be about 42%. Most of the civilian fatalities were due to famine, typhus, or Spanish flu rather than combat action. The relatively low ratio of civilian casualties in this war is due to the fact that the front lines on the main battlefront, the Western Front, were static for most of the war, so that civilians were able to avoid the combat zones.
Aftermath of World War I
Through the period from the armistice on 11 November 1918 until the signing of the peace treaty with Germany on 28 June 1919, the Allies maintained the naval blockade of Germany that had begun during the war. As Germany was dependent on imports, it is estimated that 523,000 civilians had lost their lives. N. P. Howard, of the University of Sheffield, claims that a further quarter of a million more died from disease or starvation in the eight-month period following the conclusion of the conflict. The continuation of the blockade after the fighting ended, as author Robert Leckie wrote in "Delivered From Evil", did much to "torment the Germans ... driving them with the fury of despair into the arms of the devil." The terms of the Armistice did allow food to be shipped into Germany, but the Allies required that Germany provide the means (the shipping) to do so. The German government was required to use its gold reserves, being unable to secure a loan from the United States.
