The research project, carried out in collaboration with Fondazione Openpolis, aims to fill key 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 on the availability of nursery schools, including at the sub-municipal level, with the goal of supporting more informed planning and a better understanding of territorial dynamics.
