    "abstract": "The inequality is computed through the so-called Gini index. The population\nis assumed to have the variable of interest distributed according to the Gamma\nprobability distribution. The results show that the Gini index is reduced when\nthe population is grouped. The number of individuals in the groups is the\nrelevant parameter, but this number does not need to be very large in order to\nobtain a very substantial reduction of inequality.",
