Unaccompanied and separated children leave their countries of origin for a variety of reasons. They may be fleeing from persecution, armed conflict, exploitation or poverty. They may have been sent by members of their family or decided to leave on their own – be it to ensure their survival, or to obtain an education or employment. They may have been separated from their family during flight or may be trying to join parents or other family members. Or they may have become victims of trafficking. Often it is a combination of factors.
