The total number of military and civilian casualties in World War I were about 40 million: estimates range from 15 to 19 million deaths and about 23 million wounded military personnel, ranking it among the deadliest conflicts in human history.

The total number of deaths includes from 9 to 11 million military personnel. The civilian death toll was about 8 million, including about 6 million due to war-related famine and disease. The Triple Entente (also known as the Allies) lost about 6 million military personnel while the Central Powers lost about 4 million. At least 2 million died from diseases and 6 million went missing, presumed dead. This article lists the casualties of the belligerent powers based on official published sources.

About two-thirds of military deaths in World War I were in battle, unlike the conflicts that took place in the 19th century when the majority of deaths were due to disease. Nevertheless, disease, including the 1918 flu pandemic and deaths while held as prisoners of war, still caused about one third of total military deaths for all belligerents.

Classification of casualty statistics

Casualty statistics for World War I vary to a great extent; estimates of total deaths range from 9 million to over 15 million.^[1] 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.^[2][3] These secondary sources published during the 1920s, are the source of the statistics in reference works listing casualties in World War I.^{[4][5][6][7][8]} 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.^{[9][10][11][12][12]} 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.^[13] 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.^[14]

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."^[15] 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.

Casualties by post-war (1924) borders

The war involved multi-ethnic empires such as Great Britain, France, Germany, Russia, Austria-Hungary and Turkey. Many ethnic groups in these territories were conscripted for military service. The casualties listed by modern borders are also included in the above table of figures for the countries that existed in 1914. The casualty figures by 1924 post war borders are rough estimates by Russian historian Vadim Erlikman in a 2004 handbook of human losses in the 20th century, the sources of his figures were published in the Soviet era and in post-Soviet Russia.^[76] According to the 1914–1918 Online Encyclopedia "In addition to losses suffered by African military personnel and the laborers supporting their operations, very large, but unknown numbers of African civilians perished during the war." They made an estimate of civilian losses in Africa of 750,000 based on the study by the Vadim Erlikman. They noted that Erlikman's figures are based on the work of the Russian demographer Boris Urlanis, they noted that these estimates were "imprecise" and "could be used to provide a frame of reference for further inquiry".^[25] The Oxford History of World War One notes that "In east and central Africa the harshness of the war resulted in acute shortages of food with famine in some areas, a weakening of populations, and epidemic diseases which killed hundreds of thousands of people and also cattle."^[77]

• {{flag|Nepal}}

During World War I, the Nepalese army was expanded and six new regiments, totaling more than 20,000 troops—all volunteers—were sent to India, most of them to the North-West Frontier Province, to release British and Indian troops for service overseas. Simultaneously, the Nepalese government agreed to maintain recruitment at a level that would sustain the existing British Gurkha units and allow the establishment of additional ones. The battalions were increased to thirty-three with the addition of 55,000 new recruits and Gurkha units were placed at the disposal of the British high command for service on all fronts. Many volunteers were assigned to non-combat units, such as the Army Bearer Corps and the labour battalions but they also were in combat in France, Turkey, Palestine and Mesopotamia. The Rana prime ministers urged Nepalese males to fight in the war. Of the more than 200,000 Nepalese who served in the British army, there were some 20,000 Gurkha casualties included above with the British Indian Army.^[100]

Some Chinese scholars say the number was as high as 20,000 but records kept by the British and French recruiters, show just under 2,000 lost their lives, many from the flu pandemic that swept the world starting in 1919.^[152] According to the Commonwealrh War Graves Commission, "The African combatant troops raised for the East African campaign numbered 34,000. The non-combatant porters, stevedores and followers of the Military Labour Corps 600,000. Almost 50,000 of these men were lost, killed in action died of sickness or wounds"^[11] According to The Africa Research Institute official British figures the death toll exceeded 105,000 native African troops and military carriers^[153]

• Estimates of Ottoman civilian casualties in western sources range from 2,000,000 to 2,150,000.^{[34][167][168][169]} A Russian historian in a 2004 handbook of human losses in the 20th century estimated total Ottoman civilian dead from 1915 to 1918 at about 3.2 million including the deaths of 2.2 million Armenian, Assyrian, and Greek victims of genocides committed by the Ottomans and 1,000,000 war-related civilian deaths in the Ottoman Empire due to famine and disease.(In current borders Turkey 500,000; Syria 160,000; Lebanon 110,000; Iraq 150,000; Israel/Palestine 35,000 and Jordan 20,000)^[170] According to the BBC 200,000 persons perished in the Great Famine of Mount Lebanon during the war.^[171]
• Civilian casualties include the Armenian Genocide. The total number of resulting Armenian deaths is generally held to have been 1.5 million.^[72] Other ethnic groups were similarly attacked by the Ottoman Empire during this period, including Assyrians and Greeks. Some scholars consider those events to be part of the same policy of extermination.^{[172][173][174]} The overwhelming majority of historians as well as academic institutions on Holocaust and Genocide Studies recognize the Armenian Genocide.^{[175][176][177][178]} "Despite the vast amount of evidence that points to the historical reality of the Armenian Genocide, eyewitness accounts, official archives, photographic evidence, the reports of diplomats, and the testimony of survivors, denial of the Armenian Genocide by successive regimes in Turkey has gone on from 1915 to the present".^[179]

• Denmark was neutral in the war but Germany at that time included part of Danish Schleswig. Men from this area were conscripted into the German forces and their losses are included with German casualties. Over 700 Danish merchant sailors and fisherman died, mostly due to vessels torpedoed by German submarines.^[74]
• The Danish National Archives estimated the losses of Danes in the German forces at 6,000^[180]

• Luxembourg remained under German occupation during the war. The government, led by Paul Eyschen, chose to remain neutral. This strategy had the approval of Marie-Adélaïde, Grand Duchess of Luxembourg. Some citizens were conscripted into the German forces and others escaped to volunteer for the Allies. According to the Mobile Reference travel Guide, 3,700 Luxembourgeois citizens served in the French armed forces and 2,800 gave their lives in the war. They are commemorated at the Gëlle Fra in Luxembourg.^[110]

• Norway was neutral in the war but lost ships and merchant sailors in trading through the war zones. Norway is at times referred to as the Neutral Ally due to its close relationship with the United Kingdom during the war. In 1924, the Norwegian government in a reply to a questionnaire from the International Labour Office, an agency of the League of Nations, reported 1,180 persons dead and missing in World War I.^[42]

• Sweden was neutral in the war but lost ships and merchant sailors in trading through the war zones. In 1924, the Swedish government in a reply to a questionnaire from the International Labour Office, an agency of the League of Nations, reported 800 persons dead and missing in World War I.^[42]

• The Commonwealth War Graves Commission (CWGC) Annual Report 2014–2015^[9] provides current statistics on the military dead for the British Empire. The war dead totals listed in the report are based on the research by the CWGC to identify and commemorate Commonwealth war dead. The statistics tabulated by The Commonwealth War Graves Commission are representative of the number of names commemorated for all servicemen/women of the Armed Forces of the Commonwealth and former UK Dependencies, whose death was attributable to their war service. Some auxiliary and civilian organizations are also accorded war grave status if death occurred under certain specified conditions. For the purposes of CWGC the dates of inclusion for Commonwealth War Dead are 4 August 1914 to 31 August 1921. Total World War I dead were 1,116,371 (UK and former colonies 887,711; Undivided India 73,895; Canada 64,997; Australia 62,123; New Zealand 18,053; South Africa 9,592). The Commonwealth War Graves Commission figures also include the Merchant Navy.
• Statistics of the Military Effort of the British Empire During the Great War 1914–1920, The War Office March 1922.^[56] This official report lists Army casualties (including Royal Naval Division) of 908,371 killed in action, died of wounds, died as prisoners of war and were missing in action from 4 August 1914 to 31 December 1920, (British Isles 702,410; India 64,449; Canada 56,639; Australia 59,330; New Zealand 16,711; South Africa 7,121 and Newfoundland 1,204, other colonies 507).^[144] Figures of the Royal Navy war dead and missing of 32,287 were listed separately.^[136] These figures do not include the Merchant Navy dead of 14,661.^[17]
  The losses of France, Belgium, Italy, Portugal, Romania, Serbia, Greece, Russia, the USA, Bulgaria, Germany, Austria-Hungary and Turkey were also listed in the UK War Office report.^[181]
• The official "final and corrected" casualty figures for British Army, including the Territorial Force (not including allied British Empire forces) were issued on 10 March 1921. The losses were for the period 4 August 1914 until 30 September 1919, included 573,507 "killed in action, died from wounds and died of other causes"; 254,176 missing less 154,308 released prisoners; for a net total of 673,375 dead and missing. There were 1,643,469 wounded also listed in the report.^[182]
• Sources for British Empire casualties are divergent and contradictory. The report of the War Office published in 1922 put the total number of British Empire "soldiers who lost their lives" at 908,371.^[183] On a separate schedule the War Office listed the losses of the Royal Navy at 32,237 dead and missing.^[184] It is implicit in this presentation that the figures for "soldiers who lost their lives" do not include the Royal Navy. However many published reference works list total British Empire(including the Dominions) losses at 908,371, it is implicit in these presentations that the figures for total losses include the Royal Navy.^[6][7][8]
• The War Office report puts the number of "soldiers who lost their lives" from the British Regular Army and Royal Naval Division at 702,410.^[183] This is not in agreement with the "final and corrected" figures in the 1921 report for the army published in the General Annual Report of the British Army 1912–1919, which put British Army dead and missing at 673,375 and the official compilation of Army war dead published in 1921 that put total losses at about 673,000.^[182][185] The War Office report did not explain the reason for this discrepancy; the difference is more than likely due to their inclusion of the Royal Naval Division and deaths outside of combat theaters.^[140]
• Casualties and Medical Statistics published in 1931.^[186][187] was the final volume of the Official Medical History of the War, gives British Empire, including the Dominions, for Army losses by cause of death. Total war dead in combat theaters from 1914 to 1918 were 876,084, which included 418,361 killed, 167,172 died of wounds, 113,173 died of disease or injury, 161,046 missing and presumed dead and 16,332 prisoner of war deaths. Also listed were 2,004,976 wounded and 6,074,552 sick and injured.^[188] Total losses were not broken out for the UK and each Dominion, the figures are for losses in combat theaters only and do not include casualties of forces stationed in the UK from accidents or disease, casualties of the Royal Naval Division are also not included in these figures; the losses of the Gallipoli Campaign are for British forces only, since records for Dominion forces were incomplete.^[94] Figures do not include the Royal Navy.
