When many of us hear the word "roommate," we associate it with college. We expect to graduate, and to never have to share a space again. As it turns out, this is not a reality for nearly one third of American adults aged 23 to 65, according to a new study by Zillow. In fact, the current share of adults living with roommates is the highest it has ever been since Zillow started collecting data in 1990.

So who counts as a roommate? A doubled-up household is one where two working-aged adults ( 23 to 65 ) live together without being married or in a relationship. This includes adult children living with their parents, friends living together, and so on. Doubled-up household have been on the rise since the late 1990s, according to Zillow.

"Unless current dynamics shift and income growth exceeds rent growth for a sustained period of time, this trend is unlikely to change." — Aaron Terrazas, a senior economist at Zillow
