A Poset based indicator of gender equality at sub-national level

Gender equality represents a central issue in the socio-economic background of our society and, consequently, its study is gaining increasing attention in the international debate. During the last 20 years, the international literature proposed a number of indicators that aim at measuring gender equality but there are few experiences of gender equality indicators at sub-national level. The aim of this work is twofold: on one hand we propose a regional decomposition of the European Institute for Gender Equality index (R-GEI); on the other we compare the synthetic indicator obtained following the EIGE methodology with a poset based synthetic indicator (POR-GEI). The new R-GEI is obtained reproducing the EIGE methodology, and it is compared to the POR-GEI index that exploits poset theory for aggregating indicators.
