Global demographic shifts show rising elderly populations

Global demographic trends show a historic shift as the number of people over 65 now exceeds the number of children under five. By 2025, the population aged 65 and older reached 852 million, representing 10.5% of the global total.

In Mendoza, Argentina, seniors over 65 make up approximately 12.3% of the population, totaling about 249,785 people. Guaymallén has the highest absolute number of elderly residents at 39,145, followed by Godoy Cruz and San Rafael. However, the City of Mendoza has the highest proportion of seniors at 15.9% of its total inhabitants.

Spain is experiencing intense demographic changes, with the proportion of people over 64 reaching 148% relative to those under 16. These shifts present structural challenges for pensions, labor markets, and the sustainability of welfare states.
