This week,, with help from Economic Modeling Specialists Int'l, released a report showing there are now more postings for registered nurses on its site than for any other occupation in the country.

This is not surprising: America is rapidly aging. And it's going to fall on millennials to take care of everyone. Let's see why.

Millennials are now represent the largest demographic group in the country, and since they have entered prime working age, they'll start taking most of the jobs.

At the same time, they are going to increasingly find themselves surrounded by older Americans, according to the U.S. Census.


This demographic trend is so strong that the Bureau of Labor Statistics has projected that most of the fastest-growing occupations in the U.S. are in medical, caregiving, or therapy occupations. Of note: the pay for many of the positions is so-so at best.


Make no mistake, most of this aid will be going to older people, not children. Below is the Census' outlook for the U.S. dependency ratio, broken down by the ratio of 65-years-and-older and 20-years-and-younger Americans to the U.S. working-age population. The share of older people that working Americans will be supporting grows much faster than the share of children they'll be supporting.

Many aging Americans might argue that millennials owe them a big one anyway, since so many millennials have been living at home with them, according to the U.S. Census.


But the demographics show that, if millennials are interested in a steady source of employment, they won't need that much convincing.
