The National Institute of Statistics (Istat) has sketched a frightening picture for Italy's demographic future: the country is expected to lose over 13 million citizens over the next 55 years, from 58.9 million today to 45.8 million by 2080. This loss, caused by a prolonged drop in births, now looks unavoidable in all forecasting models, suggesting a significant population reduction in both the medium and long periods. The impact of this collapse reveals substantial territorial differences on the peninsula. While the northern areas are momentarily maintaining their ground due to the driving power of the industrial sector, the south is facing the most severe contraction: by 2080, the population of Southern Italy and its islands will fall by more than a third. This dynamic will significantly affect Italian society, bringing critical challenges to the healthcare system's sustainability, the stability of historic villages, and the balance of the country's various regions.
