Municipality 4 has more than 160,000 residents, 12% of the people of Milan, and very different lifestyles coexist here, very close to each other. In fact, the territory of the municipality is diverse, uneven and characterized by a variety of neighborhoods with very different social, cultural and economic aspects. Between areas that have now become central in terms of prices and lifestyles (XXII Marzo, Montenero, Porta Romana), which characterize an area associated with greater affluence, with an ample supply of services, commercial activities and cultural facilities, and areas (Molise, Calvairate, Corvetto) where, on the other hand, different types of social hardship are found, characterized by greater economic vulnerability, less availability of services and a complex demographic composition. A complex situation, where a sense of local community and the consolidation of informal relationships struggle to ignite, amplifying loneliness and insecurities in individuals. This situation highlights a divisive situation, where a line drawn by the ring road separates the two areas, the center from the suburbs, and where a sense of local community and exchange, and the consolidation of informal relationships struggle to ignite.
