America's aging was propelled by the two largest age cohorts in the U.S. — greying baby boomers and millennials becoming adults. Fewer children also 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 younger women delaying having babies until later in life in order to focus on their education and start their careers, but also birth rates never recovered following the recession in the late 2000s, according to experts.
