<P> Casualty statistics for World War I vary to a great extent; estimates of total deaths range from 9 million to over 15 million . Military casualties reported in official sources list deaths due to all causes, including an estimated 7 to 8 million combat related deaths (killed or died of wounds) and another two to three million military deaths caused by accidents, disease and deaths while prisoners of war . Official government reports listing casualty statistics were published by the United States and Great Britain . These secondary sources published during the 1920s, are the source of the statistics in reference works listing casualties in World War I . This article summarizes the casualty statistics published in the official government reports of the United States and Great Britain as well as France, Italy, Belgium, Germany, Austria and Russia . More recently the research of the Commonwealth War Graves Commission (CWGC) has revised the military casualty statistics of the UK and its allies; they include in their listing of military war dead personnel outside of combat theaters and civilians recruited from Africa, the Middle East and China who provided logistical and service support in combat theaters . The casualties of these support personnel recruited outside of Europe were previously not included with British war dead, however the casualties of the Labour Corps recruited from the British Isles were included in the rolls of British war dead published in 1921 . The methodology used by each nation to record and classify casualties was not uniform, a general caveat regarding casualty figures is that they cannot be considered comparable in all cases . </P> <P> 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 . </P> <Table> <Tr> <Th> Nation </Th> <Th> Population (millions) </Th> <Th> Combat Deaths and Missing in Action (included in total Military deaths) </Th> <Th> Total Military deaths (from all causes) </Th> <Th> Civilian deaths (military action and crimes against humanity) </Th> <Th> Increase in civilian deaths (malnutrition and disease excluding Influenza pandemic) </Th> <Th> Total deaths </Th> <Th> Deaths as% of population </Th> <Th> Military wounded </Th> </Tr> <Tr> <Th_colspan="9"> Allies and co-belligerents of World War I </Th> </Tr> <Tr> <Td> Australia </Td> <Td> 5.0 </Td> <Td> 61,527 </Td> <Td> 59,330 to 62,149 </Td> <Td> </Td> <Td> </Td> <Td> 59,330 to 62,149 </Td> <Td> 1.19% to 1.24% </Td> <Td> 152,171 </Td> </Tr> <Tr> <Td> Canada </Td> <Td> 7.2 </Td> <Td> 56,638 </Td> <Td> 56,639 to 64,996 </Td> <Td> 1,963 </Td> <Td> </Td> <Td> 58,639 to 66,996 </Td> <Td> 0.81% to 0.93% </Td> <Td> 149,732 </Td> </Tr> <Tr> <Td> India </Td> <Td> 315.1 </Td> <Td> 64,449 </Td> <Td> 64,449 to 73,905 </Td> <Td> </Td> <Td> </Td> <Td> 64,449 to 73,905 </Td> <Td> 0.02% to 0.02% </Td> <Td> 69,214 </Td> </Tr> <Tr> <Td> New Zealand </Td> <Td> </Td> <Td> 18,166 </Td> <Td> 16,711 to 18,060 </Td> <Td> </Td> <Td> </Td> <Td> 16,711 to 18,060 </Td> <Td> 1.52% to 1.64% </Td> <Td> 41,317 </Td> </Tr> <Tr> <Td> Newfoundland </Td> <Td> 0.2 </Td> <Td> 1,204 </Td> <Td> 1,204 to 1,570 (included with UK) </Td> <Td> </Td> <Td> </Td> <Td> 1,204 to 1,570 </Td> <Td> 0.6% to 0.79% </Td> <Td> 2,314 </Td> </Tr> <Tr> <Td> South Africa </Td> <Td> 6.0 </Td> <Td> 7,121 </Td> <Td> 7,121 to 9,726 </Td> <Td> </Td> <Td> </Td> <Td> 7,121 to 9,726 </Td> <Td> 0.12% to 0.16% </Td> <Td> 12,029 </Td> </Tr> <Tr> <Td> United Kingdom (and Colonies) </Td> <Td> 45.4 </Td> <Td> 744,000 </Td> <Td> 744,000 <P> to 887,858 </P> </Td> <Td> 16,829 <P> </P> </Td> <Td> 107,000 </Td> <Td> 867,829 to 1,011,687 </Td> <Td> 1.91% to 2.23% </Td> <Td> 1,675,000 </Td> </Tr> <Tr> <Td> Sub-total for British Empire </Td> <Td> 380.0 </Td> <Td> 953,104 </Td> <Td> 949,454 to 1,118,264 </Td> <Td> 18,829 </Td> <Td> 107,000 </Td> <Td> 1,077,283 to 1,244,093 </Td> <Td> 0.28% to 0.33% </Td> <Td> <P> 2,101,077 </P> </Td> </Tr> <Tr> <Td> East -
