World War I casualties
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.
Ottoman casualties of World War I
Among the 5 million, 771,844 were military casualties killed in action and other causes. The military only covers 15% of the total casualties. The main question is what happened to 85% (spread over all millets) of the casualties, which is more but not less than 4,000,000. Ottoman statistics analyzed by Turkish Kamer Kasim (Manchester University, Ph.D.), claims that cumulative percentage was 26.9% (higher than 25% reported by western sources) of the population, which this size stands out among the countries that took part in World War I. To understand the size of the issue, Kamer Kasım's %1.9 increase on the totals adds 399,000 civilians to the total number, which has not been reported in western sources.
