Aging is the process of people growing older.
The elderly proportion of the population is growing around the world, but it is greater in developed countries.
Aging to sex ratios show women living longer than men, but this gap has been quickly narrowing since 1990.
Individuals with different racial backgrounds tend to have different experiences with old age.
In order to assist the elderly with their living and healthcare costs, the U.S. government established assistance programs like Medicare.
Global aging differs depending on the access to economic and social resources; thus, industrialized countries tend to have older populations.
