Nigeria’s smallest state is also its most populous. The country’s top economic performer, Lagos is bursting at the seams as more people arrive in search of opportunity, creating demand for roads and electricity, amongst other things.

Long seen as a bastion of the opposition, Lagos has not received the investment that it needs to grow in a well-planned way, despite the fact that it generates more tax revenue per capita than any other Nigerian state.

Lagos’s population is estimated to have swelled to more than 20 million in 2019. This number is projected to double by 2050, and the mega-city’s problems could equally double.
