Abstract: In many situations a collection of distributions need to be compared and contrasted. International comparisons of all kinds, be it health, wealth, education, income etc. are essentially about comparing aspects of their respective distributions of those variates of interest. The convergence-polarization and equality of opportunity literatures are similarly concerned with comparing collections of distributions. An aid to such comparisons would be some measure of the extent to which those distributions are collectively different. Here a Gini-like coefficient recording the extent of relative distributional inequality of a collection of (potentially multivariate) distributions is proposed.
