Makoko Floating Village, Nigeria
No official census has been conducted to this effect but there are an estimated 150,000 to 250,000 people who live in the community.
Makoko is a village that was not quite a planned town that started more than a hundred years ago. The small fishing village was built by fishermen who came from Benin to make money before it grew into an illegally constructed one-square-kilometer urban settlement.
Today, the population consists mainly of migrant workers from West African countries, trying to make a living in Nigeria.
