Although abundant in household surveys, two defining properties of anthropometrics (survival thresholds and non-monotonicity) limit their application in studying social welfare and inequality. We examine the effect of working with welfare decreasing variables on properties of the Lorenz curve, the equally distributional equivalent value and the class of Atkinson-Kolm-Sen (AKS) inequality indices. This analysis leads us to introduce new variants of AKS indices and to apply a concave Lorenz and generalized Lorenz curves that are appropriate for welfare decreasing variables. When applied to a group of five Arab countries (Egypt, Morocco, Jordan, Comoros and Yemen), the findings reveal that the ordering of health distributions below and above the optimum health endowment are very different, highlighting the need to undertake separate distributional comparisons for those who may have insufficient calorie intake from those who may be consuming excess amounts of calories.
