By the year 2050, what percent of the population is projected to be over 65 years old?

The projection that by the year 2050, 21% of the population will be over 65 years old is based on demographic analyses conducted by agencies such as the U.S. Census Bureau and various research institutions. This increase in the older population is largely attributed to several factors, including the aging of the Baby Boomer generation and advancements in healthcare that contribute to longer life expectancy.

As populations age and birth rates decline, the proportion of older adults naturally rises. This shift presents significant implications for social programs like Social Security and Medicare, as greater numbers of people will be drawing benefits concurrently. Understanding this projection is vital for policymakers and planners to prepare for the future needs of an aging population.
