The number of prisoners in the Netherlands fell from 20,463 in 2006 to 10,102 in 2016. Too many empty cells left the Dutch government looking for other uses for its prisons. So they began to fill them with migrants. The refugees—who will live in the centers for at least six months while waiting to be granted asylum status—are free to come and go as they please, practice speaking the Dutch language and learn to ride bicycles.
