America's two largest age groups propelled the changes: more baby boomers turning 65 or older and millennials who became adults or pushed further into their 20s and early 30s. Also, fewer children were born between 2010 and 2020, according to numbers from the once-a-decade head count of every U.S. resident. The decline stems from women delaying having babies until later in life, in many cases to focus on education and careers, according to experts, who noted that birth rates never recovered following the Great Recession of 2007-2009.
“In the short run, the crisis of work-family balance, the lack of affordable childcare, stresses associated with health care, housing, and employment stability, all put a damper on birth rates by increasing uncertainty and making it harder to decide to have and raise children," said Philip Cohen, a sociologist at the University of Maryland.

While people 65 and older made up 16.8% of the 331 million residents in the U.S. in 2020, the share was still significantly lower than it was in countries like Japan, Italy and Greece, where the age cohort makes up between more than a fifth and more than a quarter of the population. However, their share of the U.S. population will continue to grow as baby boomers age.
“In the long run, immigration is the only way the United States is going to avoid population decline,” Cohen said.
America aged quickly in the last decade as baby boomers lived longer and births dropped
The United States grew older, faster, last decade. The share of residents 65 or older grew by more than a third from 2010 to 2020 and at the fastest rate of any decade in 130 years, while the share of children declined, according to new figures from the most recent census.
