Population of Nigeria: Latest Estimate, Census Facts and Growth Explained

Understand Nigeria's population estimates, why different sources show different numbers, what the 2006 census counted and how UN projections should be interpreted.

What matters

Always attach a source and reference year to a population number. A live counter creates false precision because births, deaths and migration are modelled between censuses rather than counted every second.

UN medium projection

Linear interpolation between the UN WPP 2024 summary points of 230.271 million in 2024 and 374.118 million in 2054. This is an illustration, not an annual official count.

What is Nigeria's population?

The United Nations World Population Prospects 2024 summary estimated Nigeria at 230.271 million people in 2024. That figure is a model-based estimate. Nigeria's 2006 Population and Housing Census counted 140,431,790 residents, while NBS later published national projections based on demographic assumptions.

A 2026 result quoted to the last person is therefore misleading. Use “estimated” and name the dataset.

Why population websites disagree

Sources can use different baseline data, fertility, mortality and migration assumptions. They may also refer to the start, middle or end of a year. Some counters interpolate continuously and display more digits than the evidence supports.

Differences do not automatically mean one source is fraudulent. Compare the revision date, reference year and whether the value is a census, estimate or projection.

Census versus estimate versus projection

A census attempts to count people at a defined time. An estimate uses available evidence to describe a period that may already have passed. A projection asks what could happen if stated assumptions continue.

Plans for schools, health care and infrastructure may need projections, but accountability requires retaining the uncertainty around them.

Nigeria's young and growing population

NBS demographic reporting describes Nigeria as predominantly young. A young age structure creates demand for education and work now and for housing, transport and health services as large cohorts age.

National totals also hide uneven growth. Lagos, Abuja and fast-growing urban corridors can face different service pressure from rural areas or states experiencing out-migration.

How to cite the number correctly

Write: “UN DESA's 2024 revision estimated Nigeria's 2024 population at about 230.3 million.” For the census, write: “Nigeria's 2006 census recorded 140,431,790 residents.” Do not describe the UN estimate as the 2024 census.

For business planning, pair national totals with relevant age, income and local-area evidence rather than treating every resident as an addressable customer.

Why local population claims need careful definitions

Many later Nigerian projections start from census results and update them with assumptions or survey evidence. The longer the interval after a census, the more important those assumptions become. Migration caused by jobs, insecurity, education and urban growth is particularly difficult to observe continuously.

A figure for “Lagos” may refer to Lagos State, the built-up metropolitan area, an LGA or a modelled urban agglomeration. Abuja can mean the city, municipal area or wider FCT. Before comparing cities, confirm that both figures use the same boundary, reference year and method; otherwise the ranking may reflect definitions rather than a real demographic difference.

Frequently asked questions

What is Nigeria's population in 2026?

There is no completed 2026 census total; current figures are estimates or projections and should name their source.

When was Nigeria's last census?

The last completed national population census was in 2006.

What did the 2006 census count?

140,431,790 residents, according to NBS reporting.

Is a population clock exact?

No. It models change and should not be read as a live headcount.

Is Nigeria's population still growing?

The UN 2024 revision projects continued growth through 2054 and beyond, subject to assumptions.
