When considering the segment of the elderly population aged 60 and over, the 2022 survey by the Brazilian Institute of Geography and Statistics (IBGE) recorded a total of 32,113,490 older adults, representing approximately 15.6% of the current population. In 2010, this same age group represented 10.8%, indicating a 4.8% increase in just 12 years. The median age of the Brazilian population has increased by six years since 2010, reaching 35 in 2022, while the aging index rose, indicating 55.2 older adults for every 100 children aged 0 to 14, compared to 30.7 per 100 in 2010.
Notably, there is a striking difference between the speed of the demographic transition observed in developed nations and that expected in developing countries. Data published by the World Health Organization (WHO) back in 2015 showed that while France took approximately 150 years for its over-60 population to grow from 10% to 20% of the total, Brazil, China, and India are expected to take only 20 years to adapt to the same shift.
