Aging America: Baby boomers push nation's median age to almost 39 as fewer children are born – Sun Sentinel
America got older, faster during the decade ended in 2020. New census figures released Thursday show the share of U.S. residents age 65 or older ballooned by more than a third from 2010 through 2020, while the share of children declined, particularly those under age 5. Aging was propelled by the two largest cohorts in the U.S.: more baby boomers turning 65 or older and millennials moving into their 20s and 30s. Also, fewer children were born between 2010 and 2020.
