Proportional to the total population, Serbia was the country with the highest
number of casualties in the First World War. According to the first estimates
presented at the Paris Peace Conference of 1919, total Serbian casualties
were 1,250,000, over 400,000 of which were military losses while the rest
were civilian deaths. Besides direct losses, which include casualties in war
events and deaths resulting from military operations, the Serbian population
also suffered significant indirect losses originating from the reduced number
of births during the war and postwar years, increased death rate after the
war as a consequence of war events, and more intensive emigration. The paper
analyses some of the most-quoted estimates of demographic losses (the Paris
Peace Conference, Djuric, Notestein et al.), which differ in the methodology
applied, the territory covered, and the obtained results. Moreover, the paper
specifies the long-term demographic consequences of the First World War,
primarily on the population size of Serbia and its age and gender structure.
Generations that suffered the biggest losses and those whose sex structure
was disrupted the most are indicated.
