The research project, carried out in collaboration with the Openpolis Foundation, aims to fill some information gaps regarding early childhood services in the 14 Italian metropolitan cities (Bari, Bologna, Cagliari, Catania, Florence, Genoa, Messina, Milan, Naples, Palermo, Reggio Calabria, Rome, Turin, Venice) and to develop in-depth knowledge tools concerning the availability of nurseries even at the sub-municipal level, with the goal of supporting more informed planning and a greater understanding of territorial dynamics.
