GDP per capita limitations, HDI components, and living standards comparisons appear regularly in Section B; typically 8 to 12 marks.
The syllabus asks for the reasons living standards and income distribution differ both between countries and within a single country. The living-standards half of that bullet is covered above. Income is the other half: it is rarely shared out evenly within a country, and how unequally it is shared shapes the living standard of the typical person.
Income within a country is distributed unevenly for several reasons.
- Differences in skills and education. Workers with scarce, highly valued skills command much higher wages than those with few qualifications.
- Differences in wealth ownership. Households that own property, shares or businesses receive income from those assets on top of any wages, widening the gap.
- Unemployment and ill health. Households with no earner, or with members unable to work, fall to the bottom of the distribution.
- The tax and benefit system. Progressive taxes and state benefits narrow the gap; a system that taxes the poor heavily and spends little on transfers widens it.
A useful summary measure is the , a score from 0 (everyone has an equal income) to 1 (one person has all the income). You are not required to name it at IGCSE. Two countries with the same GDP per head can have very different Gini coefficients, and the one with the more even distribution usually has the higher typical living standard, because the average is not pulled up by a wealthy few while most people earn little.
Explain reasons for differences in income within a country (4 marks)
What comes up: a 4-mark question asking for two reasons why incomes differ between people within the same country — one mark per reason identified, one mark per explanation.
Write (two marks each, pick two): (1) Differences in skills or qualifications (1): workers with skills that are scarce and in high demand can command higher wages, while unskilled workers earn less (1). (2) Ownership of wealth (1): people who own property or shares earn extra income from rent, dividends and interest on top of wages, widening the gap (1). (3) Employment status (1): those who are unemployed or unable to work rely on benefits, which are usually lower than wages, placing them at the bottom of the distribution (1).
Watch out: keep "income" (a flow of earnings) separate from "wealth" (a stock of assets). The two are linked but are not the same, and a vague answer that treats them as identical risks losing the explanation mark.
