Nigeria has Africa’s largest economy because it produces more goods and services than any other country on the continent, driven by its large population, expanding services sector, agriculture and oil industry. Yet many Nigerians remain poor because the country’s economic growth has not produced enough productive jobs and higher incomes for its rapidly growing population. Inflation has further reduced people’s purchasing power, while infrastructure challenges have made it harder for businesses to expand and create better-paying jobs. The result is a country with a large economy but relatively low living standards for millions of its citizens.
This paradox became global news in 2014, when Nigeria rebased its Gross Domestic Product (GDP) for the first time in more than two decades. By updating how it measured the economy to include rapidly growing sectors such as telecommunications, entertainment, financial services and information technology, Nigeria’s GDP jumped from about US$270 billion to more than US$510 billion, an increase of roughly 89%. Overnight, Nigeria overtook South Africa to become Africa’s largest economy. The country’s economy had not suddenly doubled in size; statisticians had simply begun measuring it more accurately.
That rebasing also exposed one of the biggest misconceptions about GDP. GDP measures the total value of goods and services produced in a country, not how wealthy its citizens are. A country can have a huge economy while many of its people remain poor if that wealth is spread across a very large population or does not translate into higher incomes. Nigeria illustrates this perfectly. With about 237.5 million people in 2025, it is Africa’s most populous country, yet its GDP per capita was only about US$1,084 in 2024, showing that the country’s total economic output is spread across millions of people.
Nigeria’s economy is also far more diverse than many people assume. Following the GDP rebasing, the services sector accounted for about 57% of economic output, making it the country’s largest contributor to GDP. Agriculture remains one of Nigeria’s biggest employers, while oil, despite contributing only around 5% of GDP, continues to generate most of the country’s export earnings and a significant share of government revenue. Together, these sectors have made Nigeria Africa’s largest economy, but they have not created enough well-paying jobs for the country’s fast-growing population.
The labour market explains much of the gap between economic size and everyday living standards. According to the World Economic Forum, around 3.5 million Nigerians enter the labour force every year, meaning the economy must generate millions of new jobs annually just to keep pace with population growth. However, most Nigerians work outside formal wage employment. According to the National Bureau of Statistics, 92.3% of employed Nigerians work in the informal sector, where businesses are generally smaller, less productive and offer lower and less secure incomes than formal employment.
The scale of poverty reflects this reality. According to the World Bank, 41.8% of Nigerians were living below the international poverty line of US$3 per day (2021 purchasing power parity) in 2022. More recently, the World Bank estimated that more than 60% of Nigerians were living below the national poverty line in 2025, highlighting how rising living costs have made it harder for economic growth to improve household welfare.
Inflation has become another major reason many Nigerians do not feel the benefits of being Africa’s largest economy. Even when businesses produce more goods and services, households become worse off if prices rise faster than incomes. Nigeria’s average inflation rate reached 33.2% in 2024, pushing up the cost of food, transport, rent and other essentials. For many families, wages and business earnings simply have not kept pace with the rising cost of living.
Infrastructure has also limited how much economic growth translates into prosperity. Reliable electricity remains one of the biggest challenges facing Nigerian businesses. In 2023, only 61.2% of Nigerians had access to electricity, forcing many businesses to depend on expensive generators and higher operating costs. Poor transport networks and logistics create additional costs, reducing productivity and making it more expensive for businesses to expand, invest and hire workers.
Despite these challenges, Nigeria’s economy continues to grow. According to the World Bank, the economy expanded by 4.1% in 2024, driven largely by services. However, economic growth alone does not automatically reduce poverty. Growth improves living standards only when it creates productive employment, raises incomes and enables more people to participate in the economy.
So, why is Nigeria’s economy the largest in Africa but Nigerians are still poor? The answer is that the size of an economy is different from the prosperity of its people. Nigeria produces more economic output than any other African country, but rapid population growth, widespread informal employment, persistent poverty, high inflation and infrastructure constraints have prevented that growth from reaching millions of households.
Nigeria’s greatest challenge is therefore no longer becoming Africa’s biggest economy; it has already achieved that. The greater challenge is turning the size of its economy into higher incomes, better jobs and improved living standards so that economic growth is reflected not only in GDP figures but also in the daily lives of Nigerians.
