How many voters are there in Nigeria?

Ile-Ife voters

Numeracy is a Nigerian problem but electoral democracy is about counting numbers. Nigerians will vote to elect a president and national legislators on February 25, 2023. On 11 March, they will return to elect state legislators in 36 states and governors in 28. The numbers that will frame all these contests are now settled. They deserve close attention.

In all, 18 political parties, will field a total of 15,307 candidates, including 1,553 women for 1,491 offices, including the presidency; 28 governorship offices; 109 Senators; 360 in the House of Representatives; and 993 seats in state houses of assembly.

Voting will take place in 176,846 polling units nationwide located in 8,809 Wards or Registration Areas in 774 Local Government Areas. The Independent National Electoral Commission says it has acquired at least 194,464 Bimodal Voter Accreditation System machines for the election to be managed by over 1.4 million ad-hoc officials.

By far the most important figure, however, is the number of registered voters. When Nigeria last voted in a general election in 2019, there were 84,004,084 voters on the electoral register. Through its Continuous Voter Registration, INEC says it captured another 12,298,944 since then. When it ran these entries through its Automatic Biometric Identification System, INEC discovered that 2,780,756 (22.6 per cent) were ineligible or invalid. So, the register of voters in Nigeria has grown by 9,518,188 or 11.33 per cent to 93,522,272 since 2019.


The names on the register notionally represent the people to ultimately decide who becomes Nigeria’s next president. This is why the register deserves attention. There is another reason the number of voters matters. Complaints about “voter apathy” in Nigeria persist. The numbers and patterns seem to bear this out. In 1999, the turnout was 52.3 per cent. Officially, it grew to 69 per cent in 2003; and has fallen since then to 57.5 per cent in 2007; 53.7 per cent in 2011; 43.7 per cent in 2015; and a historic low of 34.8 per cent in 2019.

Nigeria has always had a problem with numbers, especially of people and of votes. To be fair, voting numbers can be problematic everywhere because they are ambulatory. People are not static; they die by the second, relocate, or migrate. The register of voters does not automatically change because a person whose name is on it has died or moved. So, every voter’s register, at best, represents a snapshot in time.

However, there are many curious things about voting numbers in Nigeria. One, they are an island entirely unto themselves, with no rational relationship to wider trends in the population. Nigeria’s pattern of supposedly precipitous collapse in voter turnout, for instance, is inversely proportional to the growth in Nigeria’s baseline population.

In 1999, Nigeria’s population was estimated to be 115,766,000. By the time the country voted in 2019, it had risen to 199,039,000, a growth of 83,273,000 or 71 per cent. When INEC announced the number of voters on the register for the 2023 election on 11 January 2022, the population of Nigeria was estimated to be over 219,864,000. In other words, since 1999, Nigeria’s population has grown by over 104,098,000 or 89.92 per cent.

By contrast, in 1999, Nigeria had 57 million registered voters. This rose by 5.26 per cent or three million to 60 million in 2003 and then by 1.67 per cent or one million to 61 million in 2007. By 2011, the number of registered voters had climbed by over 12 million to 73.53 million or 20.5 per cent, representing an average yearly growth rate of nearly 5.12 per cent, where previously it had grown by 1.31 per cent in 1999-2003 and 0.42 per cent between 2003-2007. By 2015, the population of registered voters had fallen to 68.83 million, a deficit of 4.7 million voters or 6.83 per cent, representing an annualized rate of reversal of 1.71 per cent. Yet, over the same period, Nigeria, a country with a median age of just under 18 years, had grown in population from an estimated 162.9 million to 181.2 million, an increase of 15.174 million or 11.23 per cent, representing an annual growth rate of 2.8 per cent.

These numbers and the patterns they reveal do not lend themselves to easy explanation. However, as the Justice Uwais presidential committee on electoral reform pointed out in its 2008 report, much of what passed for electoral numbers in Nigeria before 2011 was voodoo. Just to illustrate this point, the INEC does not have a breakdown of official results for the 2007 presidential elections but there are turnout figures for that election.

In 20 years from 1999 to 2019, Nigeria’s population rose by 71 per cent but the population of voters rose by only 50 per cent. With the latest numbers announced by INEC, Nigeria’s register of voters has grown by 36,522,272 since 1999 or 64.07 per cent, a deficit of 25.83 per cent when compared with the increase in Nigeria’s population over the same period.  It is possible to speculate about what may explain this significant deficit in growth patterns between the general population and the register of voters. Rational factors such as internal migration; agency dysfunctions in INEC, civic inertia or failure to register, or high transaction costs may explain some of this. But there remain worrying patterns that are not easily accounted for by these factors.

This leads to a second issue: Nigeria’s register of voters has always had invalid voters. The current register of voters in Nigeria dates back to November 2010 when the Attahiru Jega-led INEC set about establishing a credible register of voters for the country. The Commission had limited time to authenticate the raw data before the 2011 general election. When the Automatic Fingerprint Identification System finished its work on the 2011 register nearly four years later, INEC invalidated 4.7 million entries, which reduced the number of registered voters from 73.53 in 2011 to 68.83 in 2015 but not before these invalid 4.7 were eligible to vote in 2011.

Perhaps the biggest worry of all is with dead voters. At the beginning of 2022, the INEC explained that it cannot expunge dead voters from the register because “the country does not have reliable data of births and deaths and the commission cannot engage in arbitrary removal of the names of individuals it suspects are deceased.”

The third issue, therefore, is evidence that the number of voters on the register is grossly over-stated. In the explanation of the INEC, Nigeria’s register of voters is the classic Hotel California; it is “programmed to receive” and, for anyone with their name on it, the message is that “you can check out any time you like but you can never leave.” The implications of this for electoral integrity are staggering.

Nigerian law only allows adults to vote. Over the decade between 2010 to 2020, Nigeria’s adult mortality rate has ranged between 389.09 and 357.9 per 1,000 for men; and 359.8 to 318 per 1,000 for women. In 2020, the adult mortality rate in Nigeria was estimated at 34.25 per 100 of the population yearly. Applied to the 2019 register and adjusted down to account for the fact that the adult mortality rate is counted from 16 years, two less than the voting age, the number liable to be removed from the electoral roll would be well over six million in any election cycle.

Over three election cycles since 2011, the number liable to be expunged from Nigeria’s electoral roll could be somewhere in the region of about 20 million. Separately, at the end of 2021, the Internal Displacement Monitoring Centre, reported that Nigeria had at least 3.2 million in internal displacement. The United Nations High Commissioner for Refugees adds that there are at least another 343,000 Nigerian refugees outside the country. Admittedly not all of these are adults of voting age.

However, when you look at the numbers on Nigeria’s register of voters and account for the fact that the baseline data goes back to 2011, there is a high likelihood that up to about 25 per cent of the register are dead, dud, or displaced. When folks complain about “voter apathy” they miss one important point: Nigeria guarantees the dead a right to vote. That is antecedent to any talk of “voter apathy”.
