Data from the third quarter of 2025, released by the Institute of Statistics and Cartography of Andalusia (IECA), confirms that Seville faces a demographic scenario where mortality surpasses natality. This phenomenon, though not new, has intensified, showing a difference of 222 people in just three months, underscoring a structural transformation in the population's composition.
Between July and September, 3,557 births were recorded compared to 3,779 deaths. This consistent decline in birth rates, combined with increased life expectancy, is reshaping the population pyramid, where the base narrows and the apex expands. Despite being the Andalusian province with the highest absolute volume of both births and deaths, Seville fails to maintain positive natural growth.
A significant cultural aspect is the delay in motherhood. The dominant age group for births is between 30 and 34 years, with 1,169 cases. It is noteworthy that more births occur in women aged 40 to 44 (276) than in those under 20 (74), a reversal of historical trends. There have even been two documented births to women aged 50 or older, reflecting medical advancements and new family models.
Regarding mortality, the highest number of deaths is concentrated among those aged 85 to 89, with 640 fatalities in the quarter, indicating a society that lives longer. Longevity is a defining characteristic of Seville's demographic profile, with 32 individuals who passed away having exceeded 100 years of age. However, infant mortality is also a reality, with 13 deaths of children under one year old in the same period, the highest figure in the region, highlighting persistent vulnerabilities in the early stages of life.
This trend of negative natural population growth is not exclusive to Seville, but its population weight makes it a key indicator for Andalusia. Other provinces such as Cádiz or Jaén show more pronounced deficits relative to their population. The exception is Almería, the only Andalusian province with a positive balance in the analyzed period, while Málaga shares a similar negative trend to Seville, suggesting that this phenomenon is structural across the community.
