Data published by the World Health Organization shows that between 2015 and 2050, the proportion of the world's population over the age of 60 will rise from 12% to 22%. In absolute terms, this corresponds to an increase from nearly 1 billion to more than 2.1 billion individuals. Even more significant is the fact that, since 2020, people over 60 have outnumbered children under five, marking a historic inversion of the age pyramid.
