In this paper an innovative method to decompose by subpopulations the Pietra index is presented. The decomposition procedure is based on a two-step procedure that has been used in the literature to decompose also other inequality indexes. A such decomposition allows the evaluation of the contributions related to each subpopulation to the total value of the index. Beyond the methodological details, an application with real data about the professional football teams in Italy is described.

Abstract
In this paper an innovative method to decompose by subpopulations the Pietra index is presented. The decomposition procedure is based on a two-step procedure that has been used in the literature to decompose also other inequality indexes. A such decomposition allows the evaluation of the contributions related to each subpopulation to the total value of the index. Beyond the methodological details, an application with real data about the professional football teams in Italy is described.
