World War I casualties
First World War civilian deaths are "hazardous to estimate" according to Michael Clodfelter who maintains that "the generally accepted figure of noncombatant deaths is 6.5 million." The figures listed below include about 6 million excess civilian deaths due to war related privations, that are often omitted from other compilations of World War I casualties. The war brought about malnutrition and disease caused by the U-boat Campaign and the Blockade of Germany which disrupted trade resulting in food shortages. The civilian deaths in the Ottoman Empire include the Armenian Genocide, Assyrian Genocide, and Greek Genocide. Civilian deaths due to the Spanish flu have been excluded from these figures, whenever possible. The figures do not include deaths during the Russian Civil War and the Turkish War of Independence.
