Abstract: Formulas are derived for the Gini, Theil and Pietra coefficients for a population‐weighted mixture of double Pareto–lognormal (dPLN) distributions; they are applied to South America for 2 years. Results are also provided for the special case Pareto–lognormal and lognormal distributions. The formulas are useful for measuring regional or global inequality in large‐scale projects that utilise dPLN distributions or their special cases.
