# Cuban demographic decline and aging population > Live situation record from CLSTR: https://clstr.news/situations/cuban-demographic-decline-and-aging-population > Updated: 2026-09-07T23:08:23.000Z. Sources: 11. Developments: 2. Cuba is experiencing a significant demographic decline characterized by a shrinking population and an aging demographic. Data from the National Office of Statistics and Information (ONEI) shows the population fell to approximately 9,434,593 people, driven by a natural decrease where deaths nearly doubled births and a massive negative migratory balance. This trend has been intensifying since 2021, resulting in a median age of 45 and a notable gender imbalance with more women than men. Projections indicate this decline will continue, with the population expected to reach approximately 8.38 million within 15 years. By 2040, the aging population is projected to reach 36 percent. Juan Carlos Alfonso Fraga, deputy head of ONEI, noted that these projections are strategic for implementing economic measures and development projects. To support these efforts, the national statistical system is undergoing modernization through automation and artificial intelligence. ## Timeline ### 2026-09-07: Cuba population projected to age significantly by 2040 Cuba's population is projected to drop to 8.38 million in 15 years, with 36 percent of the population aging by 2040, according to new ONEI demographic studies. 6 sources. https://clstr.news/cluster/cuba-population-projected-to-age-significantly-by-2040 ### 2026-08-20: Cuba faces rapid population decline and aging demographic Cuba's population fell to approximately 9.4 million in 2025, driven by high migration and a birth rate significantly lower than the death rate, leading to an aging and urbanized population. 5 sources. https://clstr.news/cluster/cuba-faces-rapid-population-decline-and-aging-demographic --- Cite as: Cuban demographic decline and aging population.
