World War II casualties

World War II was the deadliest military conflict in history. An estimated total of 70–85 million deaths were caused by the conflict, representing about 3% of the estimated global population of 2.3 billion in 1940. Deaths directly caused by the war (including military and civilian fatalities) are estimated at 50–56 million, with an additional estimated 19–28 million deaths from war-related disease and famine. Civilian deaths totaled 50–55 million. Military deaths from all causes totaled 21–25 million, including deaths in captivity of about 5 million prisoners of war. More than half of the total number of casualties are accounted for by the dead of the Republic of China and of the Soviet Union. The following tables give a detailed country-by-country count of human losses. Statistics on the number of military wounded are included whenever available.
Recent historical scholarship has shed new light on the topic of Second World War casualties. Research in Russia since the collapse of the Soviet Union has caused a revision of estimates of Soviet World War II fatalities. According to Russian government figures, USSR losses within postwar borders now stand at 26.6 million, including 8 to 9 million due to famine and disease. In August 2009 the Polish Institute of National Remembrance (IPN) researchers estimated Poland's dead at between 5.6 and 5.8 million. Historian Rüdiger Overmans of the Military History Research Office (Germany) published a study in 2000 estimating the German military dead and missing at 5.3 million, including 900,000 men conscripted from outside of Germany's 1937 borders, in Austria, and in east-central Europe. The Red Army claimed responsibility for the majority of Wehrmacht casualties during World War II. The People's Republic of China puts its war dead at 20 million, while the Japanese government puts its casualties due to the war at 3.1 million. An estimated 7–10 million people died in the Dutch, British, French and US colonies in South and Southeast Asia, mostly from war-related famine.
Compiling or estimating the numbers of deaths and wounded caused during wars and other violent conflicts is a controversial subject. Historians often put forward many different estimates of the numbers killed and wounded during World War II. The authors of the Oxford Companion to World War II maintain that "casualty statistics are notoriously unreliable". The table below gives data on the number of dead and military wounded for each country, along with population information to show the relative impact of losses. When scholarly sources differ on the number of deaths in a country, a range of war losses is given, in order to inform readers that the death toll is disputed. Since casualty statistics are sometimes disputed the footnotes to this article present the different estimates by official governmental sources as well as historians. Military figures include battle deaths (KIA) and personnel missing in action (MIA), as well as fatalities due to accidents, disease and deaths of prisoners of war in captivity. Civilian casualties include deaths caused by strategic bombing, Holocaust victims, German war crimes, Japanese war crimes, population transfers in the Soviet Union, Allied war crimes, and deaths due to war-related famine and disease.
The sources for the casualties of the individual countries do not use the same methods, and civilian deaths due to starvation and disease make up a large proportion of the civilian deaths in China and the Soviet Union. The losses listed here are actual deaths; hypothetical losses due to a decline in births are not included with the total dead. The distinction between military and civilian casualties caused directly by warfare and collateral damage is not always clear-cut. For states that suffered huge losses such as the Soviet Union, China, Poland, Germany, and Yugoslavia, sources can give only the total estimated population loss caused by the war and a rough estimate of the breakdown of deaths caused by military activity, crimes against humanity and war-related famine. The casualties listed here include 19 to 25 million war-related famine deaths in the USSR, China, Indonesia, Vietnam, the Philippines, and India that are often omitted from other compilations of World War II casualties.
The footnotes give a detailed breakdown of the casualties and their sources, including data on the number of wounded where reliable sources are available.

The source of the figures is Vadim Erlikman [ru]. Erlikman, a Russian historian, notes that these figures are his estimates.
This table displays the number of people who are believed to have died in the United States by state and territory. In 1939 when World War 2 began, the Census Bureau estimated the population to be 130,879,718 people (excluding the population of Hawaii and Alaska). This list includes those who died at sea.
Included in the figures of total war dead for each country are victims of the Holocaust.
The Holocaust is the term generally used to describe the genocide of approximately six million European Jews during World War II. Martin Gilbert estimates 5.7 million (78%) of the 7.3 million Jews in German-occupied Europe were Holocaust victims. Estimates of Holocaust deaths range between 4.9 and 5.9 million Jews.
The figures for the pre-war Jewish population and deaths in the table below are from The Columbia Guide to the Holocaust. The low, high and average percentage figures for deaths of the pre-war population have been added.
Some scholars maintain that the definition of the Holocaust should also include the other victims persecuted and killed by the Nazis.
The following figures are from The Columbia Guide to the Holocaust, the authors maintain that "statistics on Gypsy losses are especially unreliable and controversial. These figures (cited below) are based on necessarily rough estimates".
Nazi Germany ordered, organized and condoned a substantial number of war crimes in World War II. The most notable of these is the Holocaust in which millions of Jews, Poles, and Romani were systematically murdered or died from abuse and mistreatment. Millions also died as a result of other German actions.
While the Nazi Party's own SS forces (in particular the SS-Totenkopfverbände, Einsatzgruppen and Waffen-SS) of Nazi Germany was the organization most responsible for the genocidal killing of the Holocaust, the regular armed forces represented by the Wehrmacht committed war crimes of their own, particularly on the Eastern Front in the war against the Soviet Union.
Included with total war dead are victims of Japanese war crimes.
R. J. Rummel estimates the civilian victims of Japanese democide at 5,964,000. Detailed by country:
Rummel estimates POW deaths in Japanese custody at 539,000. Detailed by country:
Werner Gruhl estimates the civilian deaths at 20,365,000.
Gruhl estimates POW deaths in Japanese captivity at 331,584.
Out of 60,000 Indian Army POWs taken at the Fall of Singapore, 11,000 died in captivity. There were 14,657 deaths among the total 130,895 western civilians interned by the Japanese due to famine and disease.
The total war dead in the USSR includes about 1 million victims of Stalin's regime. The number of deaths in the Gulag labor camps increased as a result of wartime overcrowding and food shortages. The Stalin regime deported the entire populations of ethnic minorities considered to be potentially disloyal. Since 1990 Russian scholars have been given access to the Soviet-era archives and have published data on the numbers of people executed and those who died in Gulag labor camps and prisons. The Russian scholar Viktor Zemskov puts the death toll from 1941 to 1945 at about 1 million based on data from the Soviet archives. The Soviet-era archive figures on the Gulag labor camps has been the subject of a vigorous academic debate outside Russia since their publication in 1991. J. Arch Getty and Stephen G. Wheatcroft maintain that Soviet-era figures more accurately detail the victims of the Gulag labor camp system in the Stalin era. Robert Conquest and Steven Rosefielde have disputed the accuracy of the data from the Soviet archives, maintaining that the demographic data and testimonials by survivors of the Gulag labor camps indicate a higher death toll. Rosefielde posits that the release of the Soviet Archive figures is disinformation generated by the modern KGB. Rosefielde maintains that the data from the Soviet archives is incomplete; for example, he pointed out that the figures do not include the 22,000 victims of the Katyn massacre. Rosefielde's demographic analysis puts the number of excess deaths due to Soviet repression at 2,183,000 in 1939–40 and 5,458,000 from 1941 to 1945. Michael Haynes and Rumy Husun accept the figures from the Soviet archives as being an accurate tally of Stalin's victims, they maintain that the demographic data depicts an underdeveloped Soviet economy and the losses in World War Two rather than indicating a higher death toll in the Gulag labor camps.
In August 2009 the Polish Institute of National Remembrance (IPN) researchers estimated 150,000 Polish citizens were killed due to Soviet repression. Since the collapse of the USSR, Polish scholars have been able to do research in the Soviet archives on Polish losses during the Soviet occupation. Andrzej Paczkowski puts the number of Polish deaths at 90,000–100,000 of the 1.0 million persons deported and 30,000 executed by the Soviets. In 2005 Tadeusz Piotrowski estimated the death toll in Soviet hands at 350,000.
The Estonian State Commission for the Examination of Repressive Policies Carried out During the Occupations put civilian deaths due to the Soviet occupation in 1940–1941 at 33,900 including (7,800 deaths) of arrested people, (6,000) deportee deaths, (5,000) evacuee deaths, (1,100) people gone missing and (14,000) conscripted for forced labor. After the reoccupation by the USSR, 5,000 Estonians died in Soviet prisons during 1944–45.
The following is a summary of the data from the Soviet archives: Reported deaths for the years 1939–1945 1,187,783, including: judicial executions 46,350; deaths in Gulag labor camps 718,804; deaths in labor colonies and prisons 422,629.
Deported to special settlements: (figures are for deportations to Special Settlements only, not including those executed, sent to Gulag labor camps or conscripted into the Soviet Army. Nor do the figures include additional deportations after the war). Deported from annexed territories 1940–41 380,000 to 390,000 persons, including: Poland 309–312,000; Lithuania 17,500; Latvia 17,000; Estonia 6,000; Moldova 22,842. In August 1941, 243,106 Poles living in the Special Settlements were amnestied and released by the Soviets. Deported during the War 1941–1945 about 2.3 million persons of Soviet ethnic minorities including: Soviet Germans 1,209,000; Finns 9,000; Karachays 69,000; Kalmyks 92,000; Chechens and Ingush 479,000; Balkars 37,000; Crimean Tatars 191,014; Meskhetian Turks 91,000; Greeks, Bulgarians and Armenians from Crimea 42,000; Ukrainian OUN members 100,000; Poles 30,000. A total of 2,230,500 persons were living in the settlements in October 1945 and 309,100 deaths were reported in special settlements for the years 1941–1948.
Russian sources list Axis prisoner of war deaths of 580,589 in Soviet captivity based on data in the Soviet archives (Germany 381,067; Hungary 54,755; Romania 54,612; Italy 27,683; Finland 403, and Japan 62,069). However, some western scholars estimate the total at between 1.7 and 2.3 million.
The Commonwealth War Graves Commission (CWGC) Annual Report 2014–2015 is the source of 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 CWGC 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 3 September 1939 to 31 December 1947.
