Section A: Key terms and recall
Define the term living standards. [1 mark]
Show model answer
Living standards refer to the level of wealth, comfort, material goods and necessities available to a person or group, including both income and non-income aspects such as health and education. 1 mark for a clear definition covering material well-being or quality of life.
Distinguish between GDP per capita and real GDP per capita. [2 marks]
Show model answer
GDP per capita is total GDP divided by population. 1 mark. Real GDP per capita is real GDP divided by population, where real GDP is adjusted for inflation, so it shows output per person in constant prices. 1 mark.
State two non-income indicators that can be used to compare living standards between countries. [2 marks]
Show model answer
Any two from: life expectancy at birth, infant mortality rate, literacy rate, school enrolment, access to clean water, access to healthcare, Human Development Index. 1 mark each.
What does the Human Development Index measure? [1 mark]
Show model answer
It measures average achievement in three basic dimensions of human development: health, education and income. 1 mark.
What does a Lorenz curve show? [1 mark]
Show model answer
A Lorenz curve shows the distribution of income or wealth in a country by plotting the cumulative percentage of income against the cumulative percentage of the population. 1 mark.
Define Gini coefficient and state what a value closer to 1 means. [2 marks]
Show model answer
The Gini coefficient is a number between 0 and 1 that measures income inequality. 1 mark. A value closer to 1 means greater income inequality, while 0 means perfect equality. 1 mark.
Section B: Applying your knowledge
In fictional Country A, real GDP per capita is high, but average life expectancy is low and many children do not finish school. In fictional Country B, real GDP per capita is lower, but life expectancy is higher and most children finish school. Which country is likely to have higher living standards? Explain your answer. [3 marks]
Show model answer
Country B is likely to have higher living standards. 1 mark. Living standards include non-income aspects such as health and education, not only income. 1 mark. Country B performs better on life expectancy and schooling, which suggests a better quality of life despite lower real GDP per capita. 1 mark.
Ravi works in a fictional city. His nominal income rises by 4 percent in a year, but prices of goods and services rise by 6 percent. Explain the effect on Ravi's real income and living standards. [3 marks]
Show model answer
His real income falls because prices rise faster than his nominal income. 1 mark. A 6 percent price rise with a 4 percent income rise means real income falls by about 2 percent. 1 mark. His ability to buy goods and services is reduced, so his material living standards are likely to fall, unless he receives other benefits. 1 mark.
A fictional government compares two regions using only GDP per capita. Explain two limitations of this approach and suggest one better way to compare living standards. [4 marks]
Show model answer
Limitation 1: It ignores income distribution, so a high average can hide poverty among some groups. 1 mark. Limitation 2: It ignores non-income factors such as health, education and environmental quality. 1 mark. A better approach is to use the Human Development Index or a basket of indicators, because this gives a broader view of living standards. 1 mark. A developed answer that explains why the better approach is more useful, for example two regions could have the same GDP per capita but different life expectancy, earns the fourth mark.
In fictional Country X, the Gini coefficient is 0.24. In fictional Country Y, the Gini coefficient is 0.58. What does this suggest about income distribution in the two countries? Explain one reason why average living standards may still differ between them. [3 marks]
Show model answer
Country Y has more unequal income distribution than Country X, because its Gini coefficient is closer to 1. 1 mark. Country X has a more equal distribution, as its Gini coefficient is closer to 0. 1 mark. Average living standards may still differ because the countries may have different average incomes, different levels of public services, or different non-income indicators such as health and education. 1 mark for any valid reason.
Section C: Explain and analyse
Explain how real GDP per capita and the Human Development Index might give different rankings for two countries. Use a fictional example to support your answer. [5 marks]
Show model answer
Real GDP per capita measures average output per person, while the Human Development Index combines income with health and education. 1 mark. A country can have high real GDP per capita but a low Human Development Index if its health and education outcomes are poor. 1 mark. Another country can have lower real GDP per capita but a higher Human Development Index if it has better life expectancy and schooling. 1 mark. Fictional example: Country P has high real GDP per capita but low life expectancy, while Country Q has lower real GDP per capita but high literacy and long life expectancy. 1 mark. Therefore Country Q may rank higher on the Human Development Index even though Country P ranks higher on real GDP per capita. 1 mark.
Discuss whether real GDP per capita is the best indicator of living standards. [6 marks]
Show model answer
Real GDP per capita is useful because it shows average output per person and is adjusted for inflation, so it allows comparisons over time and between countries. 1 mark. It is linked to material living standards because higher income can allow more consumption of goods and services. 1 mark. However, it is an average, so it hides income distribution; a high average may coexist with poverty. 1 mark. It ignores non-income factors such as health, education, leisure, environmental quality and political freedom. 1 mark. It also does not show whether growth is sustainable or whether income is spent on harmful goods. 1 mark. A broader measure such as the Human Development Index or a combination of indicators may be better for comparing living standards, so real GDP per capita is useful but incomplete. 1 mark.
Calculation section: Using data to compare living standards
| Country | Population (millions) | Real GDP ($ billion) | Life expectancy (years) | Adult literacy rate (%) |
|---|---|---|---|---|
| Country M | 20 | 600 | 72 | 85 |
| Country N | 50 | 900 | 78 | 95 |
Using the table above, calculate real GDP per capita for Country M and Country N. Give your answers in dollars. [3 marks]
Show model answer
Country M: $600 billion divided by 20 million people. $600,000 million divided by 20 million equals $30,000 per person. 1 mark. Country N: $900 billion divided by 50 million people. $900,000 million divided by 50 million equals $18,000 per person. 1 mark. Country M has higher real GDP per capita, but Country N has higher life expectancy and literacy, so Country N may have higher living standards on some non-income measures. 1 mark.
| Population quintile | Share of total income (%) |
|---|---|
| Poorest 20% | 5 |
| Second 20% | 10 |
| Third 20% | 15 |
| Fourth 20% | 25 |
| Richest 20% | 45 |
Using the table above, calculate the ratio of the income share of the richest 20 percent to the income share of the poorest 20 percent. Explain what the result suggests about income distribution. [3 marks]
Show model answer
Richest 20 percent share equals 45 percent, and poorest 20 percent share equals 5 percent. Ratio equals 45 divided by 5, which is 9. 1 mark. The richest fifth receives 9 times the income share of the poorest fifth. 1 mark. This suggests a highly unequal income distribution, which may mean average living standards hide poverty among the poorest group. 1 mark.
Challenge
In a fictional country, real GDP per capita rises for five years, but the Gini coefficient also rises and the poorest 20 percent see little change in their real income. Evaluate whether living standards in the country have improved. [6 marks]
Show model answer
Living standards may have improved for some people. 1 mark. Rising real GDP per capita suggests average output and income per person have increased, which can raise material living standards. 1 mark. However, a rising Gini coefficient means income distribution has become more unequal. 1 mark. If the poorest 20 percent have little change in real income, their living standards may not have improved, even though the average has risen. 1 mark. Non-income indicators such as health, education and access to services would also need to be considered. 1 mark. Overall, living standards may have improved for the rich but not for everyone, so the average GDP figure alone is not enough to conclude that living standards have improved for the whole population. 1 mark.
