An OECD report notes:
The current humanitarian crisis is unprecedented with an appalling and unacceptable human cost. The number of refugees is unparalleled in recent times. The diversity of nationalities, motives for migration and individual profiles also creates a huge challenge for asylum systems and welcoming communities in main European destination countries. Moreover, given the complexity of its main driving forces, there is unfortunately little hope that the situation will improve significantly in the near future.
