Refugees, Diversity and Conflict in Sub-Saharan Africa

Despite mixed empirical evidence, refugees have been blamed for spreading conflict in the countries that receive them. This paper hypothesizes that such a relationship largely depends on the resulting change in ethnic composition of refugee-hosting...

This paper hypothesizes that such a relationship largely depends on the resulting change in ethnic composition of refugee-hosting areas. To test this, this paper investigates changes in diversity in refugee-hosting areas across 23 countries in sub-Saharan Africa between 2005 and 2016. The paper then assesses the likelihood of conflict in relation to the changing level of ethnic fractionalization and ethnic polarization. Ethnic fractionalization measures the probability that two individuals drawn at random from a society will belong to two different ethnic groups and thus increases with the number of ethnic groups present. Ethnic polarization captures antagonism between individuals and is maximized when the society is divided into two equally sized and distant ethnic groups. Refugee polarization is found to exacerbate the risk of conflict, with a one standard deviation increase in the polarization index increasing the incidence of violent conflict by 5 percentage points. Such an effect corresponds to a 10 percent increase at the mean. The opposite effect is found for the fractionalization index. Additional analyses are also conducted based on individual data. Ethnic polarization increases the likelihood of experiencing physical assault by 2.1 percentage points. Inversely, the equivalent change in the ethnic fractionalization index decreases the likelihood of experiencing physical assault by 1.9 percentage points. Similar effects are found for interpersonal crime. The results should not be interpreted as evidence that refugees per se impact the likelihood of violence. Indeed, there is no evidence of a significant correlation between the number of refugees and the occurrence of conflict. Instead, the analysis points to the risk of conflict when refugees exacerbate ethnic polarization in the hosting communities. In contrast, a situation where refugee flows increase the level of ethnic fractionalization is likely to see an attenuated risk of violence. This certainly calls for specific interventions in polarized refugee-hosting communities. 2022-05-20T17:27:33Z 2022-05-20T17:27:33Z 2022-05 Working Paper http://documents.worldbank.org/curated/en/099935405182291733/IDU0d2bb8dd60616d040560b5280feaf23c219b2 http://hdl.handle.net/10986/37463 English Policy Research Working Papers;10052 CC BY 3.0 IGO http://creativecommons.org/licenses/by/3.0/igo World Bank World Bank, Washington, DC Policy Research Working Paper Publications & Research Sub-Saharan Africa

This paper hypothesizes that such a relationship largely depends on the resulting change in ethnic composition of refugee-hosting areas.

Ethnic fractionalization measures the probability that two individuals drawn at random from a society will belong to two different ethnic groups and thus increases with the number of ethnic groups present. Ethnic polarization captures antagonism between individuals and is maximized when the society is divided into two equally sized and distant ethnic groups.
