The trend of recent years toward young adults living with their parents continues, with implications for their parents who are in the run-up to retirement or are already there, according to a recent study by the Pew Research Center.

It noted that traditionally, older adults were the most likely to be living in multi-generational households—that is, due to health and other reasons they moved into their children’s homes, typically—but that became more common since the recession of 2007-2008, in many cases because young adults moved back home after being unable to support themselves independently.

Among those ages 25 through 34, in 2012 23.6 percent lived in multi-generational households, up from 18.7 percent in 2007 and 11 percent in 1980. That’s more than the 22.7 percent of adults age 85 and above who live in multi-generational households. In addition, young men are more likely to be living in such households than women, by 26 to 21 percent.

Young adults also are staying in school longer, another impact of the eroded job market in the wake of the recession, it said.
