Among Europeans ages 25-34, nearly one-in-three men and one-in-five women lived with at least one of their parents in 2008, according to a recent report from the European Commission. The highest shares were in Bulgaria for men (61%) and in Slovakia for women (42%).

These figures are higher than they are in the United States, where there has been a recent rise in multi-generational family households, as documented in a recent Pew Research Center report. According to the report, which is based on census data, 22% of men and 18% of women ages 25-34 lived in a multi-generational family household in 2008; in the vast majority of cases, they lived with one or both of their parents. In October 2009, a Pew Research Center survey found that 13% of  parents with grown children said one of their adult sons or daughters had moved back home in the previous year.
