Figures current as at September 2026. Housing data is being actively revised; check the ministry’s latest before quoting it in a proposal.

For years anyone pitching a block business, a housing scheme or a cement investment opened with the same line: Nigeria has a housing deficit of 17 million units. Or 22 million. Or 28 million, depending on which article they’d read last.

None of those numbers had a published methodology behind them. Babatunde Fashola said so publicly back in 2019, while he was the minister responsible, and got very little thanks for it. The figures kept circulating anyway, because a big number is useful when you are asking someone for money.

What the number actually is now

In January 2026 the National Housing Data Technical Committee published a proper assessment. The deficit is 14.925 million units. In July the Federal Government formally adopted 15 million as the official figure, calculated against the World Bank Adequate Housing Index and the UN-Habitat Household Crowding Index rather than against nothing in particular.

The 28 million figure has not disappeared, but it means something different from what people think. Lagos State’s housing commissioner uses it to describe where the shortage could end up if you add the 15.2 million existing homes classified as structurally defective, and if nothing improves. It is a projection with conditions attached, not a current count.

Why this should change how you pitch

Anyone you are trying to borrow from, partner with or sell to who follows this sector now knows the official number. Quoting 28 million as today’s deficit marks you out as someone working from a 2019 blog post. That is a bad first impression in a room where you are asking to be trusted with money.

The revised figure is not bad news for block producers either. Fifteen million units is still enormous. Industry estimates put the required delivery rate at around 500,000 units a year for a decade to close it. Nobody building blocks is going to run out of national demand.

The number that matters more

Here is the harder truth, and it applies whichever national figure you use: none of them tell you anything about your yard.

Blocks are heavy and cheap. Nobody hauls them past a closer producer. Your market is the radius a lorry covers before fuel eats the margin, which in most cases is a handful of kilometres. A deficit of fifteen million units nationally is irrelevant if there are four active building sites within reach of your yard and two other producers already serving them.

Before you size a machine, count the sites. Walk the radius. That number is harder to get than the national one and it is the only one that decides whether the business works.
