The convenience of a nearby supermarket is only available to a select few. Only 39% of Italians live within a few minutes' walk of a food store, with the average rising to 60% in some southern provinces. The most tangible representation of the "15-minute city" is this, a model of urban planning that has been adopted by numerous mayors of European cities and theorized by the French-Colombian scientist Carlos Moreno. It is also gaining traction in Italy as a goal to be pursued in order to enhance the quality of life of society. Advanced geo-analytics techniques were used to calculate the percentage of the population that can walk to at least one large-scale retail store (hyper and supermarkets, discount stores, and convenience stores) or small retail trade (bakeries, butchers, fishmongers, greengrocers, and so on) in 15 minutes. Barletta-Andria-Trani, Bari, and Cagliari are the three provinces with the easiest grocery store access, followed by Naples, Foggia, and Taranto, where approximately 60% of residents can reach at least one store in 15 minutes. Belluno, Rieti, Udine, and Treviso are the least served territories, with less than one in every four citizens guaranteed proximity.
