Armed conflict forces more people into sudden migration than any other event.
Victims are forced to flee their homes and homeland, often ending up in neighbouring countries as refugees. Those countries may be voluntary or involuntary hosts, and the dynamics between them and forced migrant communities are complex.
Syria remains the world's largest shock mobility crisis. More than 6.8 million Syrians have fled since 2011 and another 6.9 million remain internally displaced. The vast majority – approximately 5.2 million refugees – have found safety in neighbouring countries, primarily Turkey, Lebanon and Jordan.
