More Americans Are 'Doubling up' in Shared Households

New research from the Pew Research Center shows that more Americans are moving in with friends, family, and other adults with whom they are not romantically involved.

Shared households, defined as a household with one or more extra adults that are not the head of household, spouse or partner of the head, have increased since 1995, the earliest year with comparable data. In 1995, 29 percent, or 55 million adults had this living arrangement. In 2017, almost 79 million adults, 32 percent of the adult population, lived in a shared household, per MarketWatch's reporting on Pew Research data.

While the rise in shared living during and immediately after the Great Recession was attributed in large part to a growing number of millennials moving back in with their parents, Pew said, the longer-term increase has been partially driven by a different phenomenon: Parents moving in with their adult children, plus friends and roommates helping with the mortgage or the rent.
