How many soldiers were lost in world war 1?

Answer 1

Deaths in a war can be calculated in many ways. Usually the figures represent the deaths of soldiers on active duty, civilians killed by direct military action and similar - but ignore deaths from wounds at a later time, deaths from general privation, deaths from disease and similar.
The total number of casualties (killed and wounded) in World War I, both military and civilian, is generally estimated to be about 37 million: 16 million deaths and 21 million wounded.
The deaths include 9.7 million military personnel and about 6.8 million civilians. Allied losses were 5.7 million soldiers and the Central Powers about 4 million.
