For more young adults, there is no place like home for the holidays, and for the rest of the year, too. Ten percent of adults younger than 35 told the Pew Research Center that they had moved back in with their parents because of the recession.

They also blamed the economy for other lifestyle decisions. Twelve percent had gotten a roommate to share expenses. Fifteen percent said they had postponed getting married, and 14 percent said they had delayed having a baby.

In the Pew study, 13 percent of parents with grown children said one of their adult sons or daughters had moved back home in the past year. According to Pew, of all grown children who lived with their parents, 2 in 10 were full-time students, one-quarter were unemployed and about one-third said they had lived on their own before returning home.

According to the census, 56 percent of men 18 to 24 years old and 48 percent of women were either still under the same roof as their parents or had moved back home.
