Number of households with adult children grown

They're known as the "boomerang" adults. The children who grow up, move out, only to return to live with their parents. It's been a bit of a trend around the world and it's caught on here.

The number of households with adult children has grown by more than 100,000 since 2004 - the fastest growth of any type of household.
