Classification of casualty statistics

Estimates of casualty numbers for World War I vary to a great extent; estimates of total deaths range from 9 million to over 16 million Military casualty statistics listed here include 6.8 million combat related deaths as well as 2 million military deaths caused by accidents, disease and deaths while prisoners of war. The table lists total deaths; the footnotes give a breakout between combat and non-combat losses. The figures listed below include about 6 million civilian deaths due to war related famine and disease, these civilian losses are often omitted from other compilations of World War I casualties. The war disrupted trade resulting in acute shortages of food which resulted in famine in Europe, the Ottoman Empire and Africa. Civilian deaths include the Armenian Genocide, and it is debated if this event should be included with war losses. Civilian deaths due to the Spanish flu have been excluded from these figures, whenever possible. Furthermore, the figures do not include deaths during the Turkish War of Independence and the Russian Civil War.
