The UN refugee agency says the number of people displaced by conflict is at the highest level ever recorded.
It estimates that 65.3m people were either refugees, asylum seekers or internally displaced at the end of 2015, an increase of 5m in a year.
Meanwhile, the UN refugee chief says a worrying "climate of xenophobia" has taken hold in Europe as it struggles to cope with the migrant crisis.
The influx of people, the biggest since World War Two, has led to greater support to far-right groups and controversial anti-immigration policies.
Over half of all of them came from war-torn Syria, Afghanistan and Somalia.
