What it means
Classification starts with gross national income (GNI) per person, which is the total income earned by a country's residents divided by its population. Countries are placed into groups using thresholds that are reviewed regularly, so a country can move up or down a band over time.
Because the thresholds change, the exact boundary figures should always be taken from the latest official source. The group is wide and varied.
It includes large, fast-growing economies with strong manufacturing sectors, as well as smaller countries that rely on commodities or tourism. What they share is that most have moved beyond basic subsistence but have not yet reached the income levels of advanced economies.
For businesses, these countries are attractive because of their size, growing middle classes and rising consumer spending. Companies see opportunities in banking, retail, telecoms, healthcare and infrastructure.
The risks include currency volatility, weaker legal protection, political change and uneven infrastructure. A well-known concern is the middle-income trap, where a country grows quickly at first by using cheap labour and imported technology but then slows.
Wages rise too high to compete with low-cost producers, and the economy has not yet developed the skills and innovation to compete with richer ones. Escaping the trap generally requires investment in education, institutions and productivity.
Lenders and investors use the classification to guide decisions. Access to concessional loans, aid and favourable trade terms often depends on income group, and borrowing costs tend to reflect the country's risk profile.
A move from lower-middle to upper-middle income can bring more commercial borrowing but fewer subsidised options. Finance teams meet the classification in country risk reports, transfer pricing studies and market entry cases.
It is a quick way to group dozens of markets, but it should be a starting point only. Inflation, exchange rate stability, debt levels and the ease of repatriating profits often matter more to a specific investment than the income band.
In practice
Real-world examples.
Example
A consumer goods company plans to enter a large lower-middle-income country. The market research team estimates that 30% of households can afford its mid-priced product. It sets prices lower than in its home market and uses small pack sizes to match local spending patterns.
Example
A development bank decides which countries qualify for its lowest-cost loans. Countries in the lower-middle band qualify for some support, while those that have moved to upper-middle have fewer concessional options. The bank reviews the classifications every year.
Example
A portfolio manager compares sovereign bonds from several upper-middle-income countries. She weighs the higher yields against currency risk and political uncertainty. She limits the share of the portfolio invested in any one country.
Formula
Calculation
GNI per capita = Gross national income / Population
Suppose a country has a gross national income of $240,000,000,000 and a population of 20,000,000. GNI per capita = 240,000,000,000 / 20,000,000 = $12,000 per person. If the upper-middle-income band in some year were, hypothetically, $5,000 to $15,000, this country would fall in the upper-middle group. If its income grew by 5% a year, it would reach 12,000 x 1.05 = $12,600 after one year, and 12,600 x 1.05 = $13,230 after two.Case study
Seen in the real world.
Zandria is an illustrative, fictional upper-middle-income country with a gross national income of $90,000,000,000 and a population of 10,000,000, giving GNI per capita of $9,000. For a decade its exports of simple manufactured goods grew rapidly, but in recent years wages have risen 8% annually while productivity grew only 2%.
A fictional consultancy report warned that Zandria was at risk of the middle-income trap. Its factories were losing orders to cheaper neighbours and it lacked the research capacity to move into more advanced products. Projections suggested that income per person would stall near $10,000.
The government responded with a plan to invest 1% of national income more in education and technical training. The illustrative lesson is that moving up the income scale requires changing how the economy earns its living, not just doing more of what worked before.
Watch out
Common mistakes.
- Treating all middle-income countries as similar, when they differ widely in size, structure and risk.
- Using outdated income thresholds, when the groups are reviewed and the boundaries change over time.
- Assuming a higher average income means every citizen is better off, when inequality can be large.
Questions
People also ask.
Who decides which countries are middle-income?
Bodies such as the World Bank publish classifications based on income per person, and other organisations use their own methods.
What is the difference between lower-middle and upper-middle income?
They are two bands within the middle-income group, with the upper band holding countries closer to the high-income threshold.
Why do businesses care about the classification?
Because it signals market size, growth potential and risk, and it affects access to trade terms, aid and borrowing for the country.
