Lagos state has a housing deficit, estimated at 2.5M. This can be attributed to the state's population, which is over 21M.

According to Mr. Abiola Anifowose, the Commissioner for Physical Planning and Urban Development, the population presents a problem to the state.

“This status is not only challenging to housing provision, but exerts pressure on infrastructure in the state.

This administration is repositioning strategies of delivering decent and affordable housing units to the citizens of Lagos,” he added.

Speaking at the 2016 World Habitat Day, organised by the Ministry of Physical Planning and Urban Development in Lagos, Governor Akinwunmi Ambode highlighted the issue, the News Agency of Nigeria (NAN) reports.

Represented by his Deputy, Dr Idiat Adebule, this problem can be solved with the addition of 187, 500 new houses.
