About 50 million children worldwide are living as refugees or migrants.
A new UNICEF report highlights the growing crisis of children uprooted because of violence, poverty, conflict and gang violence.
And kids trying to get out of these situations often have no other choice but to do it alone. More than 100,000 did so last year.
The UNICEF data shows the number of displaced children has doubled in just a decade's time.
Plus, the organization said 50 million was a low estimate.
Traveling without a parent or guardian is risky. Children can end up being trafficked or abused.
And as displaced children try to reach safety, things like education and health care become nearly inaccessible.
UNICEF is calling for measures that protect migrant and refugee children from exploitation and violence, but it will likely be a long road, requiring more from the international community.
