This paper suggests generalizations of the Gini indices of "relative" and " "absolute" inequality. The new families of indices are based respect ively on the Lorenz curve and the generalized Lorenz curve. Each inde x is shown to rank income profiles in a given simplex according to so me strictly-concave, social-evaluation function, a property which the Gini indices fail to satisfy.
