Young adults are returning home in droves, with one in four 18- to 34-year-olds saying they have moved back in with parents after living independently, according to a Pew Research Center study released last month.
It's a sign of the economic times, but that's not all, according to Katherine Newman, sociology professor at Johns Hopkins University. Her new book, "The Accordion Family," examines this global phenomenon and how families feel about it.
Q Families have always doubled up in tough times. What's different this time?
