Abstract: This research presents a territorial study of the Sicilian region that integrates sociological dynamics, demographic trends, and the distribution of essential services—namely healthcare, education, and mobility—within the framework of the urban–rural divide between metropolitan and inland areas. The objective is to promote a more equitable spatial organization by shifting from an urban-centric model to a polycentric, territorially distributed vision. This transition builds upon the “15-minute city” concept, here reinterpreted and scaled up to the territorial level. The methodological approach follows a three-phase structure. First, extensive GIS-based analyses were conducted to map demographic patterns, service distribution, and social trends across the region. These were followed by accessibility assessments using isochrone analyses via the Iso4App platform, aimed at evaluating travel times to key services and identifying underserved areas. Finally, the integrated results informed a proposal for the implementation of a territorial network of eco-Positive Energy Districts (eco-PEDs), strategically located to support a polycentric regional structure. By fostering equal access to services and infrastructure, this approach enhances territorial equity and supports the principle of “territorial desirability”—contributing to a rebalancing of socio-economic and environmental conditions between metropolitan and inland areas. In doing so, it challenges current spatial hierarchies and offers a framework for inclusive, sustainable territorial development.
