Responsible AI Index

By Adedapo Adesanya

Nigeria has emerged as Africa’s highest-ranked country in the latest Global Index on Responsible AI (GIRAI), climbing 42 places globally in just two years.

Nigeria rose from 80th globally in 2024 to 38th in the world with a score of 45.93.

The GIRIA ranking boosts Nigeria’s appeal as a destination for AI talent, innovation and investment.

According to the Cape Town-based independent research and policy think tank, the ranking is one of the world’s most comprehensive assessments of responsible AI. It evaluates 135 countries across five pillars: inclusion and diversity, ethics and sustainability, labour and skills, trust and safety, and AI use in public services.

Despite that rapid adoption, the report found that public governance capacity remains weak. Average GIRAI scores stand at only about 35 out of 100 globally, while evidence of implementation exists in just 55 per cent of countries with responsible AI frameworks, dropping to 45% across the Global South.

Nigeria’s rise reflects deliberate policy efforts to strengthen its AI ecosystem.

According to the Minister of Communications, Innovation and Digital Economy, Mr Bosun Tijani, the government has accelerated work on its National Artificial Intelligence Strategy (NAIS), expanded digital public infrastructure, invested in digital skills, developed governance frameworks for emerging technologies, and strengthened international partnerships to ensure AI is deployed responsibly.

“This recognition is a testament to Nigeria’s deliberate efforts to build an AI ecosystem that is inclusive, responsible, and aligned with our development priorities,” he said.

“We believe that Africa must not only participate in the AI revolution but also contribute meaningfully to shaping how these technologies are governed and deployed globally.

“Our focus remains on creating the infrastructure, talent, and policy environment that will enable AI to deliver real value for our people and support President Bola Tinubu’s vision of building a $1 trillion economy,” he added.

The report identified Nigeria as a global “Bright Spot” for combining AI skills development with safeguards for children and vulnerable groups.

The index noted that Nigeria is among the few African countries that have attempted to simultaneously prepare citizens for an AI-driven future while strengthening protections against the risks posed by emerging technologies.

It highlighted the National Artificial Intelligence Strategy, which mandates AI literacy programmes, teacher training and broader capacity-building initiatives across the country.

The report also cited the Federal Government’s flagship 3 Million Technical Talent (3MTT) programme for delivering structured AI and machine learning training through a hybrid model designed to reach young people nationwide.

In terms of regulation, GIRAI recognised the Nigeria Data Protection Act and the General Application and Implementation Directive (GAID) 2025 for introducing enhanced safeguards for children’s personal data, including parental consent requirements and restrictions on decisions based solely on automated processing.

The report said these initiatives position Nigeria as an example of how governments can pursue AI adoption without overlooking digital rights and citizen protection.

Latest data from the Nigerian Communications Commission (NCC) has revealed that Nigeria’s teledensity rose to 86.73 per cent in April 2026, up from 85.67 per cent recorded in March, as active mobile subscriptions increased to 188.01 million, reflecting sustained expansion in access to telecommunications services across the country.

Teledensity refers to the number of active telephone connections (mobile or fixed-line) per 100 people in a specific geographic area.

This growth was driven largely by increasing demand for mobile voice and data services, as more Nigerians integrated digital communication into their daily lives for work, education, commerce, and social interaction.

The NCC’s report provided a detailed breakdown of operator performance, with MTN Nigeria retaining its dominant position as the largest mobile network operator. MTN recorded 96,391,419 active subscribers, accounting for more than half of the country’s total mobile subscriptions.

Airtel Nigeria followed with 64,670,018 subscribers, maintaining its stronghold as the second-largest provider. Globacom, the indigenous operator, recorded 23,178,597 subscribers, while 9mobile had 3,538,021 active subscribers during the period.

The competitive dynamics among these operators continued to shape the market, with each vying for greater market share through innovative data plans, network expansion, and enhanced customer service offerings.

The commission’s data also highlighted a significant technological shift in network usage, as consumers increasingly migrated to faster broadband technologies. Fourth-generation technology remained the dominant mobile network platform, accounting for 54.41 per cent of total network connections in April, up from 53.76 per cent in March.

This steady increase underscored the growing preference for high-speed internet capable of supporting video streaming, online gaming, remote work, and digital learning.

Similarly, fifth-generation technology continued its steady growth trajectory, with its market share rising from 4.20 per cent in March to 4.34 per cent in April. The gradual rollout of 5G infrastructure by operators in major cities and urban centres has begun to yield tangible results, offering lower latency and faster download speeds that are expected to drive innovation in sectors such as healthcare, agriculture, and manufacturing.

In contrast, the share of second-generation subscriptions declined to 35.93 per cent from 36.74 per cent, reflecting a gradual but clear shift away from legacy networks to higher-speed broadband services.

The third-generation segment remained relatively stable, accounting for 5.32 per cent of total connections compared with 5.30 per cent recorded in March.

This stability suggested that while 2G users were upgrading, a core group of subscribers still relied on 3G networks, particularly in rural and underserved areas where more advanced infrastructure was not yet fully deployed.

The report further showed that of the total subscriptions, 154,347,260 were on mobile GSM networks, while fixed wired internet subscriptions stood at 156,662. Voice over Internet Protocol services accounted for 220,166 subscriptions, indicating a niche but growing interest in internet-based voice communication alternatives.

The NCC also reported significant growth in broadband subscriptions, which increased to 120,684,625 in April from 117,710,397 in March.

Consequently, broadband penetration improved to 55.67 per cent from 54.30 per cent recorded in the previous month. The commission attributed this increase to continued investment in broadband infrastructure by both private operators and government-backed initiatives, as well as the growing adoption of high-speed internet services by households and businesses seeking to leverage digital tools for productivity and connectivity.

Despite the encouraging growth in broadband subscriptions, total internet data consumption declined slightly during the month. According to the report, internet usage fell marginally to 1,414,848.70 terabytes from 1,422,764.54 terabytes recorded in March.

The report suggested that while more Nigerians were gaining internet access, overall data consumption remained relatively stable, possibly due to factors such as price sensitivity, data bundle optimisation, and the varying intensity of usage across different user segments.

This moderation in consumption did not detract from the broader positive trend of expanding connectivity and digital inclusion. The NCC noted that the telecommunications sector continued to play a critical role in the nation’s economy, contributing 9.19 per cent to Nigeria’s Gross Domestic Product (GDP) in the first quarter of 2026.

This contribution underscored the sector’s transformation from a mere utility provider to a foundational pillar of economic activity, enabling everything from fintech transactions and e-commerce to remote governance and digital entertainment.

The commission added that sustained investment in broadband infrastructure, wider deployment of 5G networks, and improved quality of service would further accelerate digital inclusion, spur innovation across industries, and drive inclusive economic growth in the country.

It also emphasised the need for continued policy support, regulatory stability, and collaborative efforts between the public and private sectors to bridge the remaining digital divide and ensure that the benefits of connectivity reach every corner of the nation.
