São Paulo elderly population surpasses number of children

The state of São Paulo has reached a significant demographic milestone where the number of elderly residents now exceeds the number of children and adolescents under the age of 15. According to the Population Panel released by Fundação Seade, the aging index reached 101.0 in 2025, representing 101 elderly individuals for every 100 young people.

This shift is driven by declining fertility rates and increased life expectancy. Since 1950, the aging index has grown 8.7 times, rising from approximately 12 elderly people per 100 children to the current levels. The population aged 60 or older totals 8.4 million people, accounting for 18.4% of the state's inhabitants. Women constitute a larger portion of this demographic, making up 10.5% of the total population compared to 7.9% for men.

The data also highlights the influence of Generation X (born between 1965 and 1980) as they enter their senior years. Regional disparities are evident, with the highest aging indices found in the northwestern region, such as in Turmalina, while the lowest indices remain concentrated in the southern part of the state.
