The financial crisis might appear to be the reason younger generations are moving back in with parents or grandparents, but it’s not really a new trend. The percentage of middle-aged adults living with their parents has been growing steadily in the United States since the 1970s. Recession or not, the economic benefits are obvious. Working adults can save money, expenses can be split and the family network can save on child care. Beyond the economic upside, “Many grandparents tell us not only that they love having their family under their roof; they also love being needed again,” said Dr. Georgia Witkin, a senior editor for Grandparents.com. “They say it brings purpose to their days, and meaning to their lives.” A full 50% of adults say it improved familial relations, with only 8% saying it was detrimental, according to the Pew Research Center.
