Highlights

.  We examine the relationship between ethnic diversity and poverty.
.  We measure poverty using a wide range of indicators from the World Bank and UNDP. Ethnic diversity is measured by both fractionalization and polarization.
.  Ethnic diversity increases poverty.

Summary: We examine the relationship between ethnic diversity and poverty for a cross-sectional sample of developing countries. We measure diversity using indices of ethnic and linguistic fractionalization, and measure poverty using the multidimensional poverty index (MPI), multidimensional poverty headcount (MPH), intensity of deprivation, poverty gap, and poverty headcount ratio. We find that ethnic and linguistic fractionalization contributes to poverty levels. Specifically, after controlling for endogeneity, we find that a standard deviation increase in ethnic fractionalization is associated with a 0.32-, 0.44- and 0.53-standard deviation increase in the MPI, MPH and the intensity of deprivation, respectively. Moreover, a standard deviation increase in ethnic fractionalization is associated with between a 0.34- and 0.63-standard deviation increase in the population living below $1.90 and $3.10, the poverty gap at $1.90 and $3.10 a day and the headcount ratio at $1.90 and $3.10 a day. Similar results are also observed for linguistic fractionalization with standardized coefficients between 0.53 and 0.93. We find that our results are robust to alternative ways to measure poverty and ethnic diversity including ethnic polarization as well as alternative approaches to address endogeneity.
