The Dispute Over Nigeria’s Population Figures and State Demands

Nigeria’s argument over population data is often described as a dispute over the 2023 census figures. That description needs an important qualification: Nigeria did not complete a national population and housing census in 2023, so there is no officially released 2023 headcount for the states. The disagreement concerns projections, planning estimates and competing claims about what a new enumeration might reveal.

The last completed national census was held in 2006, when the National Population Commission (NPC) recorded about 140 million people. Since then, federal agencies, international organisations, state governments and researchers have relied on estimates that place Nigeria’s population far higher. Those figures influence public spending, parliamentary representation, infrastructure planning and the distribution of political influence.

The planned 2023 census was postponed shortly before the end of President Muhammadu Buhari’s administration. Security concerns, political transition, funding requirements and operational preparations were among the issues associated with the delay. President Bola Tinubu’s government has since inherited the task of determining when and how the next exercise should take place.

For state governments, the issue is practical as much as political. A population count affects classrooms, hospitals, roads, housing, employment programmes and local government planning. It also raises sensitive questions about migration, religious and ethnic balance, urban growth and access to national resources. The dispute therefore extends beyond a number on a spreadsheet.

Why Nigeria Still Lacks A New Official Count

The 2006 census remains the most recent completed nationwide enumeration accepted as an official benchmark. Nigeria has conducted smaller surveys and demographic studies since then, while the NPC and other institutions have produced projections. These exercises can estimate population trends, but they do not replace a census that identifies households and residents across every local government area.

The difference matters because Nigeria’s population is highly mobile. People move from rural communities to cities such as Lagos, Abuja, Port Harcourt, Kano and Ibadan in search of work, education and security. Seasonal migration also affects farming regions, mining areas and commercial centres. A projection may capture broad growth while missing the speed at which particular neighbourhoods are expanding.

The postponed exercise was intended to use digital technology, geographic mapping and improved field operations. Supporters argued that electronic data collection could reduce duplication and improve the speed of processing. Critics, however, pointed to the cost of the exercise, insecurity in several parts of the country, weak transport links and the risk that political pressure could influence the final figures.

This is why references to “2023 census results” should be treated carefully. There are estimates associated with 2023, including international population projections, but there is no final state-by-state census table from the NPC for that year. Confusing an estimate with an official count can turn a technical debate into a misleading political claim.

What The States Are Contesting

Lagos is central to the discussion because its population has grown through internal migration, international business and rapid urban expansion. The state’s metropolitan area extends beyond administrative boundaries, with commuters and residents moving between Lagos and neighbouring Ogun. State authorities have repeatedly argued that official planning must reflect the scale of the wider urban corridor, not merely older administrative assumptions.

Kano and other large northern states also have strong reasons to demand a credible count. Their governments need reliable figures for schools, health services, agriculture, water supply and urban infrastructure. Northern officials and community leaders have frequently raised concerns that insecurity, difficult terrain and limited access to some communities could result in under-enumeration.

Southern states often emphasise a different problem: their daytime populations can be considerably larger than the number of permanent residents recorded in a locality. Business districts, university towns, oil-producing areas and transport hubs attract workers who may retain family homes elsewhere. Rivers, Delta, Akwa Ibom and Cross River, for example, require population data that reflects both settled communities and economic activity linked to energy, ports and construction.

There is no single state position. Some governors want a quick census because years without fresh data have weakened planning. Others are wary of accepting a process they believe could be compromised by insecurity, poor logistics or political manipulation. States may also support an enumeration in principle while disputing the likely figures for particular local government areas.

Why Population Numbers Carry Political Weight

Nigeria’s population figures are linked to representation and public finance. Census data can influence the drawing of constituencies, the allocation of development programmes and the way federal institutions assess demand. Although revenue sharing is not determined by population alone, larger populations can strengthen a state’s argument for a greater share of national attention and investment.

This creates incentives for states to challenge figures that appear too low and, in some cases, to promote estimates that support their claims. Population counts have consequences for the balance between regions and for the perceived strength of political blocs. That is why census debates can become emotionally charged, particularly where ethnic, religious and regional identities overlap.

The controversy is not unique to Nigeria. In Australia, the Australian Bureau of Statistics conducts a national Census every five years, with the 2021 exercise recording about 25.5 million people. Governments, supermarkets, transport authorities and property developers use the data to understand local demand. A new housing estate outside Melbourne or a growing suburb in western Sydney can quickly change the need for schools, bus routes and medical services.

The Australian comparison also highlights the value of public trust. People are accustomed to seeing census information translated into data about household size, rental patterns, languages spoken and commuting habits. Nigeria’s longer gap between completed censuses makes each new exercise more politically consequential and increases public suspicion about how the figures will be produced.

The Practical Cost Of Outdated Data

Without a current census, planners must combine old population figures with household surveys, birth and death records, school enrolment, voter registration and service-use data. Each source has a different purpose and level of accuracy. Voter registration, for example, records eligible voters rather than the entire population, while school enrolment excludes children outside formal education.

This weakens decisions about where to build facilities. A state may know that a district is growing but lack the household-level information needed to determine whether it needs a primary school, a maternity centre, a larger water scheme or improved waste collection. In informal settlements, residents may be missed because addresses are not standardised or households change frequently.

The issue is visible in everyday markets. A supermarket chain planning new outlets in Brisbane or Perth can compare population density with household income, transport access and shopping habits. Nigerian businesses face a more uncertain environment when demographic baselines are old. Banks, mobile operators, logistics companies and retailers must often rely on private surveys or rough estimates before investing in a rapidly changing community.

Outdated data also affects the housing debate. In Lagos and Abuja, rental demand, overcrowding and commuting patterns cannot be understood fully through old census figures. A reliable count would help distinguish between population growth, household fragmentation and temporary migration. Those distinctions matter when authorities plan affordable housing, public transport and land-use controls.

What A Credible Census Would Require

The first requirement is an agreed timetable supported by adequate funding and transparent preparation. The NPC would need to publish clear information about mapping, enumeration areas, recruitment, training, technology and the treatment of people in hard-to-reach communities. State governments and local councils should be involved without being allowed to control the results.

Security is another major concern. Enumerators need safe access to rural settlements, border communities, conflict-affected areas and densely populated urban neighbourhoods. Any areas that cannot be reached should be identified publicly, with a clear explanation of how the gap will affect the results. Silent exclusions would damage confidence even if the overall methodology were sound.

Technology can improve accuracy, but it cannot solve every problem. Digital devices may reduce paperwork and make data transmission faster, yet they depend on electricity, connectivity, trained personnel and secure systems. Independent audits, field verification and strong privacy safeguards are necessary to prevent errors and reassure residents that personal information will not be misused.

Australia’s census experience offers a useful reference without providing a ready-made model. The ABS has faced its own debates over privacy, online participation, regional access and the needs of remote communities. Nigeria would need methods suited to its own realities, including informal settlements, nomadic populations, internal displacement and communities affected by insecurity.

The final test will be whether states accept the outcome. That requires consultation before the count, technical observers during the process and a credible mechanism for resolving complaints afterwards. Publishing the methodology and releasing detailed results in stages could help citizens, researchers and journalists identify anomalies without turning every disagreement into a regional confrontation.

Population data should serve people before it serves political arguments. Readers who encounter claims about a state’s supposed 2023 census figure should check whether the number comes from an official census, a projection, a survey or a political statement. National Weekender’s contact page is available for readers who wish to share documented information, corrections or local evidence about population changes.

A trustworthy census will not settle every dispute over resource allocation, but it can give Nigeria a stronger factual foundation for those debates. Until that exercise is completed, state claims should be reported with context, estimates should be labelled as estimates, and public officials should be held to a standard of evidence.
