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.
France
France was a member of the Triple Entente when World War I broke out. A small part of Northern France was occupied, but France and its allies emerged victorious against the Central Powers at a tremendous human and material cost. World War I left 1.4 million French soldiers dead, 4% of its population. Between 27 and 30% of soldiers conscripted from 1912–1915 were killed. The interbellum years were marked by intense international tensions and a variety of social reforms introduced by the Popular Front government (annual leave, eight-hour workdays, women in government).
