Aging America: Baby boomers push nation's median age higher as fewer children are born
America got older, faster during the decade ended in 2020
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.
The declining percentage of children under age 5 was particularly noteworthy in the figures from the 2020 head count released Thursday. Combined, the trends mean the median age in the U.S. jumped from 37.2 to 38.8 over the decade.
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.
