We propose an index of geo-linguistic dispersion that measures the extent to which spatial distribution of a socio-economic attribute is dispersed or clustered. Differently from the existing statistics measuring the extent of clustering such as e.g. Moran’s I (1948), the attribute does not have to be measurable even in the partial ordering sense. Our index is also different from Greenberg’s (1956) index of linguistic diversity since the latter is invariant with respect to the spatial distribution of languages. Our index decreases with the opportunity costs of traveling, and with the extent to which a particular attribute is geographically clustered. We envision applying the GLD index in the studies examining the associations between socio-economic outcomes, and the extent to which the values of a socio- economic attribute are diverse and geographically dispersed or clustered.
