Population aging, a global social phenomenon, is changing the world's population structure at an unprecedented rate. This is not simply a change in the total population. It is also having a profound impact on the economy, society, culture, and healthcare systems. By internationally accepted standards, a country or region is considered an aging society when people aged 60 and over account for 10% or more of its total population, or when people aged 65 and over account for 7% or more. These standards provide a clear benchmark for measuring the degree of population aging.
