What this dot point is asking

This is OCR GCSE Geography B (J384) Component 2, People and Society, the opening enquiry of Dynamic Development: "How is development measured, and how reliable are the measures?" OCR expects you to explain what development means and why it is hard to define, describe the economic, social and combined measures (especially GNI per capita, the HDI and the Gender Inequality Index), and explain the limitations of single indicators.

What is development?

Economic, social and combined measures

OCR wants you to know several measures and what each one captures.

  • Economic measures. GNI per capita (Gross National Income per person) is the total income of a country divided by its population, usually adjusted for the cost of living. It measures average wealth.
  • Social measures. Life expectancy, infant mortality, literacy rate, years of schooling and access to clean water and sanitation all measure aspects of quality of life.
  • Combined measures. The HDI brings several together into one score.

The limitations of single indicators

A single figure is convenient but can mislead.

  • It is an average that hides inequality within a country: between regions, between rich and poor, and between men and women. A wealthy capital can disguise deep rural poverty.
  • It can be out of date or unreliable, especially where a large informal economy goes unrecorded.
  • It measures only one aspect of development, so wealth alone says nothing about health, education or rights.

For these reasons, geographers prefer combined measures (the HDI) and a range of indicators to judge development.

Try this

Q1. State two social measures of development. [2 marks]

  • Cue. Life expectancy and literacy rate (also infant mortality, access to clean water).

Q2. Explain what the HDI measures and why it is useful. [4 marks]

  • Cue. It combines income, health (life expectancy) and education into one score, so it captures quality of life rather than just wealth.

A 4-mark "Explain" question assessing AO1 and AO2 of development measures. Markers reward a developed comparison.

Award credit for: GNI per capita measures only wealth (the average income per person), so it misses how that wealth is shared and how people actually live. The HDI combines three things, income (GNI per capita), health (life expectancy) and education (years of schooling), into a single score between 0 and 1, so it captures quality of life, not just money. A country can be quite wealthy from oil but score lower on the HDI if its health and education are poor, so the HDI gives a fuller, more balanced picture. Top answers explain what the HDI adds (health and education), not just say it is better.

A 6-mark "Assess" question marked by levels of response, assessing AO1, AO2 and AO3, with a judgement.

Strong answers explain that single indicators (such as GNI per capita, birth rate or literacy) are simple, quick to compare and widely available, so they are useful for ranking countries. They then give the limitations: a single figure is an average that hides huge inequalities within a country (between regions, rich and poor, men and women), can be out of date or unreliable (especially where the informal economy is large), and measures only one aspect of development. A good judgement concludes that single indicators are useful as a first comparison but can mislead, so combined measures such as the HDI and a range of indicators give a more reliable picture. Markers reward the balance and the judgement.
