Nigeria has retained its position as a lower-middle income economy in the latest World Bank Group Country Income Classifications, updated on July 1 using 2025 gross national income (GNI) per capita data.

With a GNI per capita of about $1,250, Nigeria remains below the threshold required to move into the upper-middle income category, reflecting the country’s ongoing struggle with inflation, currency volatility, and slow per capita income growth despite recent macroeconomic reforms. The classification is significant because it influences Nigeria’s eligibility for concessional loans and development assistance and serves as a benchmark for tracking economic progress.

The 2026 update assessed 218 economies. Six countries moved up an income category: Jordan, Micronesia, the Philippines, Sri Lanka, and Viet Nam advanced to upper-middle income, while Togo rose from low to lower-middle income. None moved down.

Globally, economies are classified as low income (≤ $1,135), lower-middle ($1,136–$4,495), upper-middle ($4,496–$13,935), and high income (> $13,935). The United States recorded $88,810, placing it firmly in the high-income group, while China’s $13,660 places it at the upper end of upper-middle income.

In Sub-Saharan Africa, most countries remain low-income, though Nigeria and several peers are lower-middle, and only a few – such as South Africa and Botswana – are upper-middle. The share of low-income economies worldwide has fallen from 30% in 1987 to just 11% today, reflecting broad progress, though Nigeria’s trajectory highlights uneven advancement across regions.

For Nigeria to advance into the upper-middle income bracket, per capita income must exceed $4,495. This will require sustained productivity growth, stronger job creation, and effective implementation of reforms. Analysts warn that without tackling inflation and improving infrastructure, Nigeria risks stagnating in the lower-middle category despite its large economy and population.

In Sub-Saharan Africa, the latest data shows that 21 countries are low-income, 20 are lower-middle, and 6 are upper-middle.

The World Bank’s lending framework is closely tied to its income classifications, with each bracket determining the type of financing available to countries. The International Development Association (IDA) provides support to low-income economies through highly concessional loans and grants, often carrying very low or zero interest rates and long repayment periods. These facilities are designed to help the poorest nations finance essential infrastructure, reduce poverty, and strengthen social services.

For lower-middle income economies, the Bank offers blended lending, which combines concessional IDA financing with non-concessional International Bank for Reconstruction and Development (IBRD) loans. This arrangement is intended to support countries that are transitioning out of low-income status but continue to face significant development challenges, giving them access to both softer and market-based financing.

IBRD lending, by contrast, is directed at upper-middle and high-income economies. It consists of non-concessional loans at near-market terms, typically used for large-scale infrastructure projects, institutional reforms, and financial sector development. These loans provide affordable financing for countries with stronger creditworthiness but which still require support to modernise and sustain growth.
