As a Country, We Aged Fast, Especially in 2021
The last two decades have seen the country grow continuously older. Since 2000, the national median age – the point at which one-half the population is older and one-half younger – has increased by 3.4 years, with the largest single-year gain of 0.3 years coming in 2021, bringing it to 38.8 years, according to the U.S. Census Bureau. Median age for most states also increased from 2020 to 2021.
