Bonus: What in the World - Why are so many young people leaving Nigeria?

Nigeria is Africa’s economic powerhouse - so why are so many young people trying to leave and find opportunities in other countries? It’s become so common there’s even a word for it: Japa, Yoruba for escape.

Last year, Nigeria’s immigration service issued a record number of passports - almost 2 million.

So when we were in Lagos we spoke to the BBC’s Faith Oshoko, who explained what drives young professionals to move abroad.

And we chatted to students - would they ever Japa? And would they come back?
