2. Lagos, Nigeria
The main city of Africa, it is one of the worst cities to live in. Boko Haram, the Islamic militant organization is the main reason for its worst city tag.
Kidnapping, stealing on gunpoint, sectarian violence etc are common in the city.
The culture is slowly seeping away from the city and finding recluse in the rural areas, the infrastructure is raw and unmentioned accounting for severe sanitary conditions in many areas including the sectors where the business is supposed to be flourishing.
