Nope. The share of young adults (18-31) living in their parents’ home was relatively constant from 1968 (the earliest comparable data available) to 2007, at about 32%. So it's nothing new, just something else to whine about. The 32% has increased to 36% since 2007 due to that great recession thingy.
