The Digital Divide Within Cities: How Urban Inequality Shapes Tech Access in Africa

Most conversations about Africa’s digital divide default to a familiar map: connected cities on one side, disconnected villages on the other. That framing is not wrong, but it is incomplete. Drive fifteen minutes from Victoria Island in Lagos to Ajegunle, or from Nairobi’s Westlands to Kibera, and the internet changes character long before the scenery does. The digital divide in African cities is not a border between urban and rural life. It is a fault line running through the middle of the cities themselves.

One City, Two Networks

Nigeria’s broadband story illustrates this well. As of May 2025, national broadband penetration stood at 45.57 percent, short of the government’s own target of 70 percent, according to a review by Phillips Consulting. The same review notes that Lagos and Abuja enjoy reasonably strong fibre and 4G coverage, while large stretches of the country still run on outdated 2G or nothing at all. But that coverage map hides an internal one. Fibre density in Lagos is heaviest in Ikoyi, Victoria Island, Lekki, and the business districts that host banks, telecom offices, and serviced apartments. It thins out sharply once you cross into Ajegunle, Makoko, or the outer reaches of Ikorodu and Badagry, where population density is often higher, but infrastructure investment has historically been lower.

This is not simply a matter of income. It is a matter of where telecom operators, driven by return-on-investment economics, choose to lay cable first. Wealthier, commercially active neighbourhoods get fibre rollouts because they promise faster payback. Lower-income, high-density settlements are seen as harder to serve profitably, so the network arrives later, if it arrives at all.

The Cost of Being Connected

Even where signal exists, affordability decides who actually uses it. The Alliance for Affordable Internet found that the average cost of 1GB of data in Africa runs at roughly 5.7 percent of monthly income, nearly three times the United Nations’ affordability benchmark of 2 percent, as reported by Global Voices Advox. For a resident of a formal, salaried job in central Lagos, that cost is an inconvenience. For someone earning daily wages in an informal settlement, it can mean rationing data to WhatsApp messages and skipping video calls, job applications that require uploads, or online classes altogether.

Nigeria’s National Bureau of Statistics has documented the scale of the resulting gap. Its ICT Access and Usage report found that only 23 percent of rural Nigerians used the internet, against more than 60 percent in urban areas, a pattern the GSMA’s Mobile Connectivity Index corroborated with similar figures, as detailed in a Vanguard report on the country’s widening divide. What that same reporting flags, and what deserves more attention, is the concentration effect: Lagos, Abuja, and Port Harcourt alone are projected to account for as much as 75 to 80 percent of total data consumption nationally. That is not evidence of broad urban connectivity. It is evidence that a handful of neighbourhoods within a handful of cities carry most of the country’s digital activity. At the same time, much of urban Nigeria, not just rural Nigeria, is left out of the count.

Life Inside the Gap: Makoko and Beyond

Nowhere is the intra-urban divide more visible than in Lagos’s waterfront settlements. Makoko, a community of stilted homes built into the lagoon, is home to anywhere between 85,000 and over a million residents depending on the estimate used, and for years it barely existed on any digital map. A 2019 initiative by Code for Africa and the Humanitarian OpenStreetMap Team set out to change that, mapping streets, structures, and addresses so residents could access financial services, deliveries, and emergency response that require a locatable address, as described in Devex’s coverage of the project. The effort was as much about infrastructure as it was about visibility. A resident without a mapped address cannot easily open a bank account, register a business, or receive a delivery, regardless of how strong the phone signal overhead might be.

Researchers tracking informal settlements across the continent describe this as a structural pattern, not a Lagos peculiarity. A recent analysis in Democracy in Africa notes that settlements like Kibera, Mathare, and Mukuru in Nairobi function the same way Makoko, Ajegunle, and Ilaje-Bariga do in Lagos: as the default, not the exception, for low-income urban housing. Formal infrastructure, digital or otherwise, is calibrated for middle- and high-income neighbourhoods, leaving informal settlements to build their own workarounds, from shared phone lines to community cyber cafés.

What This Means for Policy and Business

For telecom operators and infrastructure investors, the intra-city divide is arguably a more addressable problem than the urban-rural one, since the last mile is measured in kilometres rather than hundreds of them. But it requires treating low-income urban wards as a distinct market segment rather than folding them into broad “urban” coverage statistics that flatter national numbers. For policymakers, it means broadband targets should be measured at the ward or settlement level, not just the state level, so that a well-connected Ikoyi does not mask a disconnected Ajegunle in the same local government area.

For businesses building digital products for African cities, from fintech to e-commerce to logistics, the practical implication is that “urban” is not a reliable proxy for “reachable.” The customer three streets away may be functionally offline, not because the technology has not arrived in their city, but because it never turned down their street.
