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.
African military systems after 1900
Unlike the African troops of Britain, who saw very little action on European battfields during World War I or World War II, France deployed hundreds of thousands of African fighting men to aid its cause, including some 300,000 North Africans, some 250,000 West Africans and thousands more from other regions. Over 140,000 African soldiers for example, fought on the Western Front during World War I and thousands of others fought at Gallipoli and in the Balkans. French West African troops fought and died in all the major battles of the Western Front, from Verdun (where they were instrumental in recapturing a fort) to the Armistice. Some writers (Lunn 1999) argue that towards the end of World War I, the black soldiers were increasingly been used as shock troops, and were absorbing three times as many casualties as white French troops. The French did offer such incentives as citizenship for those who fought, and French leader Clemeanceau pushed for continued recruitment of West Africans to fight for France, maintaining that it was better blacks were killed than long-suffering white Frenchmen. One in five West African combat soldiers who fought in World War I died in the war, compared to less than 17% for the French. Colonial troops such as Indian regiments in British employ suffered less.
