Nigeria’s electoral journey since 1999 has been marked by both progress and persistent challenges. At the heart of every credible election lies one critical element: the voter register. It is the foundation upon which the entire electoral process rests. If that foundation is compromised, the integrity of the elections — and by extension, democracy itself — comes into question.

For over two decades, the Independent National Electoral Commission (INEC) has grappled with issues of voter impersonation, multiple registration, inflated figures, and demographic manipulation. But technology and data analytics are changing the game. From the Bimodal Voter Accreditation System (BVAS) to the Automated Biometric Identification System (ABIS), Nigeria is slowly building a data-driven electoral architecture.

This article explores how voter registration analytics — powered by legislation, technology, and forensic oversight — can combat electoral fraud in Nigeria, while acknowledging the challenges that remain.

Part One: The Numbers Tell a Troubling Story

Nigeria’s Voter Turnout Crisis

Before examining solutions, we must understand the problem. Nigeria’s voter registration figures reveal a paradox: as the registered voter population has grown, actual participation has steadily declined.

Data from 1999 to 2023 tells a sobering story :

In raw terms, Nigeria has added over 35 million new registered voters since 1999. Yet the number of people who actually voted in 2023 was lower than in 1999. Turnout peaked in 2003 and has declined steadily since then, reaching its lowest level in 2023 .

This trend raises fundamental questions: Are these registered voters real? Are they eligible? And why are millions of registered citizens choosing not to participate?

The Voter Register’s Growth: A Closer Look

INEC has described Nigeria’s biometric voter register as “the largest electronic database of Nigerians in existence” . The numbers bear this out:

· 2011: Over 73 million voters biometrically captured

· 2015: Approximately 68 million (after register cleanup)

· 2019: Over 84 million

· 2023: Approximately 95 million biometrically captured

While impressive in scale, this growth has not been without controversy. The African Democratic Congress (ADC) recently raised concerns over what it called “statistically implausible” registration figures, particularly from Osun State, which recorded 393,269 pre-registrations in a single week — a figure higher than the 275,815 new voters the state added between 2019 and 2023.

Part Two: The Legislative Framework for Data-Driven Elections

The Electoral Act 2022: A Watershed Moment

The Electoral Act 2022 represents a fundamental shift in Nigeria’s approach to electoral data. For the first time, technology received explicit legal backing, transforming digital devices from mere administrative tools into “statutorily protected pillars” of the electoral system .

Section 47(2) of the Act has been described as the watershed provision. It mandates the use of electronic accreditation devices, giving BVAS both operational and legal legitimacy. Before this, previous technologies lacked the “teeth” of the law, leaving INEC vulnerable to technicalities in election tribunals .

Key Provisions for Voter Register Integrity

The Electoral Act 2022 contains several provisions that enable data-driven voter registration analytics :

Section 9 empowers INEC to compile, maintain, and update a national register of voters on a regular basis. The register must exist in both electronic and hard copy formats.

Section 10 mandates continuous registration of all eligible persons and requires INEC to provide every political party with the names and addresses of all registered voters within 60 days after each year.

Section 12 establishes clear qualification criteria: a person must be a Nigerian citizen, at least 18 years old, and must not register in more than one registration center.

Section 15 grants citizens and political parties the right to obtain certified true copies of the voters’ register for any state, local government, or polling unit upon payment of prescribed fees.

Section 19 requires INEC to display the voters’ register for public scrutiny for seven days, both at registration areas and on its website, and to accept objections and complaints within 14 days.

Perhaps most importantly, the Act established strict penalties for registration offenses:

· Registering more than once: Fine of up to ₦100,000 or imprisonment for up to one year (Section 12(3))

· Holding more than one voter’s card: Fine of up to ₦500,000 or imprisonment for up to one year (Section 16(3))

· Unlawful possession or sale of voter’s cards: Fine of up to ₦500,000 or imprisonment for up to two years (Sections 22–23)

Proposed Reforms for the Next Electoral Act

Civil society organisations driving electoral reforms — including Yiaga Africa, the Centre for Media and Society (CEMESO), and the Kimpact Development Initiative — have proposed far-reaching amendments to strengthen Nigeria’s electoral data framework.

Key proposals include:

Periodic Independent Audit of the Voter Register: The CSOs are seeking mandatory independent audits that must be open to public scrutiny to identify duplicate, multiple, or ineligible entries.

Early Voting Provisions: This would enable security personnel, INEC staff, accredited journalists, and observers to cast their votes before the main election day — reducing the logistical pressures that often compromise data integrity.

Alternative Voter Identification: An amendment to Section 47(1) would allow voters to present other valid means of identification, such as driver’s licenses, international passports, or national ID cards.

Part Three: Technology as the Guardian of the Register

BVAS: Ending the Era of Voter Impersonation

The Bimodal Voter Accreditation System (BVAS) has been described by INEC Chairman Professor Joash Amupitan as a “foolproof mechanism” for voter verification.

Speaking at the 2025 Digital Nigeria International Conference, Amupitan declared, “The BVAS device has become our frontline defense against identity fraud, ensuring that only the rightful, eligible voter can be accredited at the polling unit. With the biometric safeguards now in place, voter impersonation has been effectively eliminated from our electoral system.”

The Chairman backed this assertion with data from the Anambra State Governorship election, where 6,879 BVAS devices were deployed. Over 99% of polling unit results were uploaded to the INEC Result Viewing (IReV) portal on Election Day itself .

ABIS: Detecting Multiple Registrations

Behind the scenes, INEC deploys the Automated Biometric Identification System (ABIS) to detect double registrations. This system cross-references biometric data — fingerprints and facial recognition — across the entire voter database to identify individuals attempting to register multiple times.

According to INEC, pre-registration figures are only provisional. Registrants must complete their biometrics in person at designated centers before being added to the national register. The ABIS system serves as the final gatekeeper.

The Connectivity Challenge

Despite these technological advances, significant challenges remain. INEC has openly acknowledged that connectivity remains a logistical headache .

With 176,846 polling units tucked into swamps, perched on mountains, and hidden in far-flung communities, achieving real-time upload of results remains one of the toughest battles for transparency on Election Day.

As Professor Amupitan admitted, “A tool like the BVAS is only as good as the network it runs on.”

INEC has committed to engaging the Nigerian Communications Commission (NCC) and network providers to address this challenge, while actively exploring alternative technologies to bridge connectivity gaps.

Part Four: The Analytics Challenge — Making Sense of Voter Data

The Osun Anomaly: When Numbers Don’t Add Up

The recent controversy over voter registration figures in Osun State illustrates the importance of robust data analytics.

According to INEC’s report, Osun State recorded 393,269 pre-registrations in a single week. The ADC described this as “statistically implausible,” noting several red flags:

· The figure exceeded the total 275,815 new voters registered in Osun between 2019 and 2023

· Even at the peak of political mobilisation in 2022, Osun had never produced more than 823,124 votes cast in a governorship election

· The figure represented nearly 20% of all eligible adults in the state registering within seven days

The ADC called on INEC to conduct and publish a full forensic audit of the pre-registration data, including a state-by-state breakdown of both physical and online registrations. The party also demanded disclosure of server logs, bandwidth distribution, and regional access reports for the registration portal.

INEC’s Defence

INEC dismissed the claims as unfounded. Rotimi Oyekanmi, Chief Press Secretary to the INEC Chairman, noted that Osun’s lead was not unusual. He recalled that during the 2021/2022 CVR exercise, Osun consistently topped the charts — recording over 400,000 pre-registrations by the 11th week.

Oyekanmi explained that pre-registration figures are only provisional and that ABIS would detect any double registrations during the in-person biometric capture phase.

The Case for Forensic Audits

The Chartered Institute of Forensics and Certified Fraud Investigators of Nigeria has pledged support to INEC in tackling disparities in voter registration figures. Dr. Iliyasu Gashinbaki, President of the Institute, urged the deployment of technology and forensic tools to safeguard the credibility of the process.

“Our role is to help INEC do the right thing, deploy technology, and apply forensic methods,” Gashinbaki explained. “That is our focus.”

He stressed that the institute was not avoiding its responsibilities but rather adopting a strategic approach to engaging with politically sensitive matters.

Part Five: Emerging Threats and Responses

Preventing Multiple Registrations

In December 2025, INEC announced intensified efforts to eliminate multiple registrations. The Commission strengthened collaboration with the Judiciary and the Nigeria Immigration Service (NIS) as part of a broader strategy to protect the voters’ register.

The Resident Electoral Commissioner for Sokoto State, Umar Yusuf Garba, disclosed that INEC is working closely with courts to validate age declarations and relevant documents while engaging the NIS to ensure that only Nigerian citizens — particularly in border communities — are registered as voters .

Garba stated, “We want to be certain that registrants are Nigerians and that they have attained the constitutional voting age of 18, using verifiable records such as birth documents, primary school certificates, and court-issued age declarations” .

The Non-Citizen Registration Risk

Given Nigeria’s porous borders, preventing non-citizens from infiltrating the electoral register has become increasingly critical. The partnership with immigration authorities is designed to address this vulnerability .

Call for an Electoral Offences Tribunal

Garba reiterated calls for the establishment of a special electoral offenses tribunal, describing it as a necessary reform to deter violations, strengthen the electoral process, and boost public confidence.

“INEC is learning, improving, and correcting past mistakes. With dedicated personnel and stronger institutions, we are steadily moving towards a more credible electoral system,” he said .

Part Six: Policy Recommendations for Data-Driven Electoral Integrity

Immediate Actions

1. Mandatory Pre-Registration Audits

Before any new registration period begins, INEC should conduct a forensic audit of existing data to establish baseline figures. This would make anomalies immediately visible.

2. Real-Time Anomaly Detection

INEC should deploy machine learning algorithms to flag statistically implausible registration patterns in real-time — not weeks or months after the fact.

3. Public Dashboards

Citizens should have access to live dashboards showing registration figures by state, LGA, and polling unit. Transparency builds trust.

4. CSO Access to Server Logs

As proposed by the ADC, civil society organisations should be granted access to anonymized server logs, bandwidth distribution, and regional access reports for independent verification.

Medium-Term Reforms

5. Periodic Independent Audits

The CSO proposal for mandatory independent audits of the voter register — open to public scrutiny — should be adopted.

6. Early Voting Implementation

Enable security personnel, INEC staff, and accredited observers to vote before election day, reducing the pressure that often leads to logistical failures.

7. Alternative Voter Identification

Allow voters to present driver’s licenses, international passports, or national ID cards when BVAS experiences technical failures.

Long-Term Structural Changes

8. Special Electoral Offences Tribunal

Establish a dedicated tribunal to prosecute registration fraud and other electoral offenses swiftly and effectively .

9. Continuous Voter Education

Section 2 of the Electoral Act should be reviewed to make voter education a shared responsibility among INEC, the National Orientation Agency (NOA), CSOs, and the media.

10. Blockchain for Voter Registration

Explore blockchain technology for immutable, transparent, and auditable voter registration records.

Conclusion: From Data to Democracy

Nigeria has made significant strides in leveraging technology and data analytics to combat electoral fraud. The Electoral Act 2022 provided the legal foundation. BVAS and ABIS have delivered measurable results. The national biometric voter database is one of the largest in Africa.

But the journey is far from complete.

The declining voter turnout — from 69% in 2003 to just 27% in 2023 — suggests that technical solutions alone cannot restore public trust. Transparency, accountability, and citizen engagement are equally essential.

As INEC Chairman Professor Amupitan stated, “Our mission is simple. To ensure that every eligible voter is accurately verified, every vote is properly counted, and every result is transparently shared. Technology has helped us secure these foundations of democracy.”

The question now is not whether Nigeria can deploy data analytics to combat electoral fraud. The question is whether the political will exists to follow the data wherever it leads — even when the findings are uncomfortable.

When citizens can finally verify the integrity of the voter register with a click rather than a protest, Nigeria will have crossed a fundamental threshold: from being victims of electoral manipulation to being its verifiers.
