We examine the effect of the 2002-2007 civil conflict in Côte d'Ivoire on children's health status using household surveys collected before, during, and after the conflict, and information on the exact location and date of conflict events. Our identification strategy relies on exploiting both temporal and spatial variation across birth cohorts to measure children's exposure to the conflict. We find that children from regions more affected by the conflict suffered significant health setbacks compared with children from less affected regions. We further examine possible war impact mechanisms using rich data on households' experience of war from the post-conflict survey. Our results suggest that conflict-induced economic losses, health impairment, displacement, and other forms of victimization are important channels through which conflict negatively impacts child health.
