Educational assortative mating in Italy: what can Gini's homogamy index still say?

Alessandra De Rose, Romina Fraboni


The homogamy index proposed by Gini is applied to describe the changes occurred in marital choice - across time and regions in Italy. The relevant increase in education by women has provoked an increase in the number of homogamous couples and in an increasing proportion of women who marry downward. Relevant differences are observed in the case of informal unions and mixed marriages.
