Acoording to the report, the 18 to 35-year-olds living in the United States currently top the seniors by 500,000. That gap is expected to widen as baby boomers between the ages of 51 and 69 tend to deal with more health issues as they approach their 70s and 80s.

The Pew Research Center who analyzed the report projects millennials will peak at just over 81 million in 2036, beating the baby boomer’s peak population of 78.8 million in 1999.

Gen Xers, born between 1965 and 1980 are also on track to outnumber baby boomers but not until 2028.

In the future it may not be as easy for younger generations to outnumber older ones because the numbers show that all people in general are living longer. A prime example are the centenarians, those 100 or older. In 2015 there were nearly half a million of them living throughout the world which was four times as many in 1990 according to estimates from the United Nations. They project 3.7 million centenarians will be alive in 2050.
