A family of refugees steps off a boat or arrives at a border. Should they be allowed to enter? This question provokes passionate responses in countries around the world these days.
But there's a second set of questions: if they are admitted, where will they live? How will they learn a new language? How will their children be educated? Will they have access to the training needed to get jobs to help them support themselves?
In short, how can they be integrated into society?
These questions are at the heart of a new report from the EU, which warns of a potential "lost generation" of migrants, people who enter Europe to build better lives but then find little chance of integrating into society.
