Answer :
The number of Americans aged 65 and older increased by more than 17 times since 1900, nearly quadrupling (from 4.1% in 1900 to 16% in 2019). (from 3.1 million to 54.1 million).
What proportion of Americans are above 65?
The United States has more than 56 million adults aged 65 and older, or roughly 16.9% of the population, according to the U.S. Census Bureau.
The increase in the senior population has also been fueled by increases in life expectancy. Life expectancy at birth increased between 1900 and 1960, rising for males from 51 to 74 years and for women from 58 to 80 years, largely due to declines in infant, childhood, and early adult mortality.
