Measuring Regional Ethnolinguistic Diversity in Sub-Saharan Africa: Surveys vs. GIS

Boris Gershman () and Diego Rivera

No 2016-05, Working Papers from American University, Department of Economics

Abstract: This paper compares two approaches to measuring subnational ethnolinguistic diversity in Sub-Saharan Africa, one based on censuses and large-scale population surveys and the other relying on the use of geographic information systems (GIS). The two approaches yield sets of regional fractionalization indices that are moderately positively correlated, with a stronger association across rural areas. These differences matter for empirical analysis: in a common sample of regions, survey-based indices of deep-rooted diversity are much more strongly negatively associated with a range of development indicators relative to their highest-quality GIS-based counterparts.
