HDI vs. highways: The missing link in Nigeria’s development strategy

In the bustling hearts of Lagos and Abuja, the skyline tells a story of ambition. From the sweeping spans of the Second Niger Bridge to the gleaming tracks of the Lagos-Ibadan railway, Nigeria’s landscape is increasingly punctuated by hard infrastructure. To the casual observer or political strategist, these projects serve as shorthand for progress—solid, photogenic, and easily commissioned.

But as we stand in 2026, we must confront a sobering reality: the heartbeat of a nation cannot be measured by the thickness of its asphalt.

While our concrete structures rise, the quality of life for the average Nigerian continues to experience quiet stagnation. To truly gauge development, we must look beyond highways and bridges to indicators that reflect human welfare.

One of the most widely accepted frameworks for measuring development globally is the Human Development Index (HDI), developed by the United Nations Development Programme. The HDI evaluates development across three key dimensions: life expectancy, education attainment, and income per capita. It recognises that development is fundamentally about expanding human capability rather than simply expanding physical assets.

Nigeria currently ranks approximately 164th out of 193 countries on the HDI scale, placing it within the low human development category despite being Africa’s largest economy by GDP size. This reflects a structural imbalance between infrastructure expansion and improvements in human welfare.

The great divergence

Recent economic data illustrates a worrying disconnect. While Nigeria recorded GDP growth estimated at about 4 percent, poverty levels continue to rise. Estimates suggest that approximately 63 percent of Nigerians, about 140 million people, live below the poverty line. This signals what may be described as a “Great Divergence”: a country that is physically modernizing while its people struggle with declining social outcomes.

Human development indicators reveal significant gaps that infrastructure alone cannot close.

Nigeria’s life expectancy remains between 54 and 55 years, far below the global average of over 73 years. This reflects persistent structural challenges in healthcare access, maternal health outcomes, nutrition, and preventive care systems.

Education indicators present an equally concerning outlook. Nigeria has the highest number of out-of-school children in the world, estimated at about 18.3 million. Mean years of schooling remain approximately 7.6 years, suggesting that a significant portion of the population lacks the educational foundation required to compete in a knowledge-driven global economy.

Income distribution also reveals structural inefficiencies. Nigeria’s Gross National Income per capita is higher than that of several countries ranked above it in HDI performance. This negative gap indicates that national wealth is not effectively translating into improved well-being for the majority of citizens.

In effect, wealth is being reflected in physical structures rather than in human development outcomes.

Infrastructure as a means, not an end

Infrastructure remains an essential enabler of economic activity. Roads reduce logistics costs, rail systems improve mobility, power supports industrial productivity, and ports facilitate trade.

However, infrastructure must support broader development outcomes.

A country may build highways, but if unemployment remains high, development outcomes remain weak.

Airports may be modernised, but if healthcare systems remain underfunded, life expectancy will not significantly improve.

Rail networks may expand, but if millions of children remain out of school, future productivity remains constrained.
Infrastructure is therefore necessary, but not sufficient, for development.

The infrastructure-first fallacy

There is a persistent belief in policy circles that infrastructure investment will automatically translate into poverty reduction. Evidence suggests otherwise.

Large infrastructure projects are often capital-intensive but not labor-intensive enough to significantly reduce unemployment.

Furthermore, infrastructure requires strong institutional capacity for maintenance and optimisation. Without strong institutions, infrastructure can become underutilized or deteriorate rapidly.

A rail line that citizens cannot afford to use does not improve mobility outcomes. A power plant that does not translate into a reliable electricity supply does not improve productivity. A road that does not improve access to education or healthcare does not significantly improve human welfare.

Infrastructure without human development impact becomes a monument rather than a catalyst for progress.

Lessons from other economies

Countries that consistently rank high on HDI demonstrate the importance of balancing infrastructure investment with human capital development.

Rwanda, despite limited natural resources, has significantly improved life expectancy through deliberate healthcare reforms.

Mauritius has achieved one of Africa’s highest HDI rankings through sustained investment in education quality and institutional effectiveness.

Singapore transformed its economy through simultaneous investment in infrastructure, education, skills development, and governance quality.

These examples demonstrate that development outcomes improve when infrastructure is complemented by investments in people.

Measuring what truly matters

If Nigeria continues to define development primarily through visible infrastructure, it risks becoming a nation of impressive projects but limited human progress.

Real development is the invisible infrastructure:
• the literacy level of a child in remote areas
• the survival rate of mothers during childbirth
• the purchasing power of households
• the employability of graduates
• the accessibility of healthcare services

Nigeria’s long-term competitiveness will depend not only on the roads it builds but also on the skills of its workforce, the strength of its institutions, and the health of its population.

Success in the coming decade should not be measured by ribbon-cutting ceremonies alone but by measurable improvements in HDI indicators.

Until Nigeria records sustained improvements in life expectancy, education quality, and income distribution, infrastructure expansion alone cannot be considered a reliable measure of development.

Infrastructure may shape the landscape, but human capital shapes the future.

The missing link in Nigeria’s development strategy is not more highways alone but stronger human development outcomes.
