Paying the full blood tax: combat exposure and mortality among French WW1 soldiers

Based on individual-level data from military registers, this paper explores the trajectories of French conscripts during the Great War. The sample studied consists of more than 20,000 men of the recruitment classes of 1900 to 1914. Besides a descriptive analysis, which aims at providing both a statistical portrait of conscripts and an insight into their wartime paths, regression analyses are carried out to identify factors associated with (1) fitness for armed service, (2) assignment to a civilian position, (3) infantry assignment, and (4) war mortality. The main focus is on whether there were inequalities in combat exposure and mortality in relation to socioeconomic status. The results suggest that some social groups were more exposed to war violence than others. In particular, farmers were more likely to be considered fit to fight than industry/craft workers and (most of) men working in the tertiary sector. They were also more likely to join the war as infantrymen and less likely to move to a civilian position. All this partly explains why mortality was higher in this group. The differences in mortality risk according to socioeconomic status were, however, of lower magnitude than those associated with military characteristics.
