America's elderly are no longer the most likely group to be living with another generation, thanks to the continued surge of 25-34 year olds who are increasingly moving back in with their parents or another relative.

A Pew study released Thursday shows that nearly one in five Americans lived with a member of another generation in 2012, an all-time high. A record 57 million Americans, or 18.1 percent of the adult population, lived with someone who was a member of a different generation, with adults aged 25-34 driving the growth as a "major component" of the trend.

As the study noted, this means that young adults have now usurped seniors as the most prevalent members of multi-generational households:

Historically, the nation’s oldest Americans have been the age group most likely to live in multi-generational households. But in recent years, younger adults have surpassed older adults in this regard. In 2012, 22.7% of adults ages 85 and older lived in a multi-generational household, just shy of the 23.6% of adults ages 25 to 34 in the same situation.
