“The median age in the United States has risen from 35.3 years old in 2000 to 37.9 years old in 2016, according to data released by the U.S. Census Bureau. Baby boomers — Americans born between 1946 and 1964 — are responsible for the increase as boomers began reaching the age of 65 in 2011. As more boomers reach that age, the median will continue to rise. In terms of sheer numbers, however, the boomers have already lost their dominance, as millennials — Americans between the ages of 18 and 34 — now account for eight of the 10 most common ages.”
