Boomeranger 

A child who moves out of their family's house, purportedly to get jobs and/or start their own lives, but who return shortly thereafter to live with their parents again.

As the cost of living increases and jobs become harder to find, more and more parents find that instead of having an empty nest, they have boomeranger children living with them.
