Abstract

Il saggio ripercorre le tappe fondamentali, e analizza le motivazioni teoriche, che hanno influito sulla definizione dell'indice di Gini così come viene applicato ai giorni nostri. In particolare, partendo dal concetto di differenza media semplice proposta da Corrado Gini nel 1912 per le applicazioni in ambito statistico ed economico, si evidenziano le diversità tra il rapporto di concentrazione proposto dallo stesso Gini nel 1914 e l'indice di Gini usualmente utilizzato oggi, alla luce della sua interpretazione geometrica con la spezzata di Lorenz proposta da Gaetano Pietra nel 1915.
