In early 1994, Kagera, a region in northwestern Tanzania, was flooded by more than 500,000 refugees fleeing from the
genocides of Burundi and Rwanda. I use this population shock and a series of topographic barriers that resulted in
variation in refugee intensity to investigate the short-term and long-term causal effects of hosting refugees on outcomes
of local children. This strategy provides evidence of adverse effects over one year after the shock: a worsening
of children’s anthropometrics (0.3 standard deviations); an increase in the incidence of infectious diseases (15 percentage
points to 20 percentage points); and an increase in mortality for children under age 5 (7 percentage points).
