In plain words
The gap between the richest and poorest countries is vast: income per person can be fifty times higher in one than in another. The causes feed on each other, which is what makes the gap hard to close.
Low income means little saving, little saving means little investment, and little investment means income stays low.
5 things to know
- Developing countries tend to have lower income per head, lower productivity, faster population growth, and a large share of workers in the primary sector.
- Low saving leads to low investment in machinery and infrastructure, so productivity and incomes stay low. This is the cycle of poverty.
- Education: fewer children finish school, so the workforce is less skilled. Healthcare: life expectancy is lower, and illness keeps people from working.
- Natural resources help only if they are used well. Depending on one primary export is risky, because its price can swing widely.
- Consequences: big differences in living standards, migration of workers to richer countries, and reliance on foreign aid, loans and investment.
Tips and tricks
- Link the factors in a chain when you explain them: low income, so low saving, so low investment, so low productivity, so low income again.
- Use the terms "developed" and "developing" with a reason: name the indicator, such as income per head or share of jobs in the primary sector.

Any two of: low income per head, low productivity, fast population growth, a large primary sector, low saving and investment, lower levels of education and healthcare.
Explain how low levels of saving can keep a country poor.[3]
Show answerHide answer
With little saving, banks have little to lend, so firms cannot invest in machinery and the government cannot build infrastructure. Productivity stays low, so incomes stay low and people still cannot save.
Explain why relying on the export of one primary product is risky for a country.[3]
Show answerHide answer
The world price of a primary product can change sharply. If it falls, or the crop fails, the country's export earnings and incomes fall, and it has little else to sell.
