Are areas that host encamped refugees more likely to experience communal conflict, and under what conditions? Building on insights from the refugee studies literature suggesting that settling refugees in camps can intensify intercommunal tension in host communities, this article investigates the effect of refugee encampment on the occurrence of communal conflict at the subnational level in sub-Saharan Africa. It first tests for a general relationship between the overall presence and population intensity of encamped refugees and communal conflict before assessing whether this relationship is moderated by local-level characteristics, including interethnic linkages and political and economic marginalization within the host region. The basic findings show that communal conflict occurs more frequently in regions where refugees are camp-settled. Tests for interactive effects indicate that refugee camps have a significant marginal effect on conflict only if they are located in areas with politically marginalized host groups. Origin country/host region ethnic ties are shown to exert significant moderating effects. Moreover, results from an extended set of analyses show that the form of refugee settlement matters, as the presence and population intensity of self-settled refugees are related to decreases in the occurrence of communal conflict.
