British and German wounded, Bernafay Wood, 19 July 1916.

Classification of Casualty Statistics

Estimates for World War I casualty numbers vary to a great extent. Military casualty statistics listed here include combat related deaths as well as losses caused by accidents, disease and prisoner of war deaths. The table lists total deaths; the footnotes give a breakout between combat and non-combat losses.
Most civilian deaths during World War I were due to war related famine and disease. Civilian deaths due to the Spanish flu have been excluded from these figures, whenever possible. Furthermore, estimates of civilian deaths include the Armenian Genocide, and it is debated to which degree this event should be included.
The data listed here is from official sources, whenever available. These sources are cited below.
