a. Contrasting ways of defining development (economic criteria and broader social and political measure) and measuring development (Gross Domestic Product (GDP) per capita, the Human Development Index (HDI), measures of inequality and indices of political corruption).
This statement covers two ways of defining development, economic and broader social and political, and the measures used to assess it. Gross Domestic Product (GDP) per capita divides total output by population: US$2,400,000,000 shared among 3,000,000 people gives US$800 per person. The Human Development Index (HDI) combines life expectancy, schooling and income into a score between 0 and 1. Measures of inequality, such as the Gini coefficient, show how unevenly income is shared. Indices of political corruption, such as the Corruption Perceptions Index, rate how clean institutions are perceived to be; higher scores mean less corruption. Use these measures together, because each captures a different aspect of development.
b. How countries at different levels of development (developing, emerging and developed) have differences in their demographic data (fertility rates, death rates, population structures, maternal and infant mortality rates).
Compare demographic data across developing, emerging and developed countries. Know each indicator: fertility rate (average children per woman), death rate (deaths per 1,000 people per year), population structure (age-sex pyramids showing youth and elderly dependency), maternal mortality (deaths per 100,000 live births) and infant mortality (deaths of under-ones per 1,000 live births). Developing countries often show high fertility, high infant and maternal mortality and wide-based pyramids; developed countries show low fertility, low death rates and ageing structures. Emerging countries, such as India or Brazil, usually sit between these, with falling birth rates and improving health. Use a named example for each level and explain causes, such as healthcare access, education and income.
Your focus
- Match each development measure to the aspect of development it assesses.
- Calculate GDP per capita from a given total GDP and population, giving the answer in US$ per person.
- Explain why several development measures are used together rather than one alone.
Show all 6 objectives
- Define fertility rate, crude death rate, maternal mortality and infant mortality with correct units.
- Compare demographic indicators between developing, emerging and developed countries using named examples.
- Explain how healthcare, education and income contribute to differences in demographic data.
Topic 2: 2.1 There are different ways of defining and measuring development exam tips
Marking Points
- Distinguishes economic criteria from broader social and political measures when defining development.
- Identifies GDP per capita as total GDP divided by population, expressed as a value per person.
- Explains that the HDI combines life expectancy, education and income into a single score.
- Recognises measures of inequality, such as the Gini coefficient, as showing how unevenly income or wealth is shared.
- Identifies indices of political corruption as measuring perceptions of corruption in public institutions.
- Identifies each named demographic indicator and defines it accurately, including its unit such as per 1,000 or per 100,000 live births.
- Describes the typical fertility rate and death rate pattern for developing, emerging and developed countries.
- Explains population structure differences using age-sex pyramid features such as a wide base or an ageing profile.
- Compares maternal and infant mortality between levels of development, using named examples for each.
- Links each difference to a cause such as healthcare, education, income or family planning.
Examiner Tips
- 💡Identify which measure each option describes before comparing the answers.
- 💡Check the units in each option: GDP per capita is a value per person, while the HDI is a score between 0 and 1.
- 💡Reject any option that claims a single measure captures every aspect of development.
- 💡Match each named example to its development category before writing, so the comparison is secure.
- 💡Use two contrasting levels in each answer and state the direction of difference, such as higher or lower.
- 💡Check that each indicator has its correct unit, and keep fertility and death rates separate.
Common Mistakes
- Treats GDP per capita as showing how fairly wealth is shared; correct this by using inequality measures to show distribution.
- Assumes a high GDP per capita automatically means a high HDI; correct this by noting that the HDI also includes health and education.
- Describes the HDI as a measure of economic output alone; correct this by listing its health and education components.
- Confuses corruption indices with measures of inequality; correct this by matching each index to the aspect of development it actually measures.
- Confuses fertility rate with birth rate; defines fertility as the average number of children a woman is expected to have.
- Uses a country name without stating its level of development; names the category the country belongs to.
- Treats emerging countries as identical to developed countries; describes them as showing intermediate patterns.
- Gives a mortality figure without its unit; states per 1,000 or per 100,000 live births as appropriate.
