Do young people from islands or overseas territories often feel forced to leave home to build a future?

I released a documentary about Martinique (French Caribbean) where many students have to move thousands of kilometers away to study in mainland France. It made me wonder how common this experience is in other places around the world.

For people from islands, remote regions, or former colonies: did you experience something similar?
