How do we measure how developed a country is, and why is no single indicator enough?

What this dot point is asking
The SQA wants you to know the indicators used to measure development (social, economic and composite), explain the difference between developed and developing countries, and explain why using a single indicator can be misleading so a range of indicators is more reliable.
Economic and social indicators
Indicators fall into two main groups, plus composite measures that combine them.
Composite indicators
A composite indicator combines several measures into one, giving a more balanced picture than any single figure.
Developed and developing countries
The world is often split into developed (richer, more industrialised) and developing (poorer, often more reliant on farming) countries:
- A developed country (for example the UK or Japan) has high GNP per person, low birth and death rates, low infant mortality, high life expectancy and high literacy.
- A developing country (for example Malawi or Bangladesh) has low GNP per person, a high birth rate, higher infant mortality, lower life expectancy and lower literacy.
Why one indicator is not enough
A single figure can give a false impression for three main reasons:
- Averages hide inequality. GNP per person is an average, so a few very rich people can hide widespread poverty.
- Money ignores quality of life. Income alone says nothing about health, education or clean water.
- Data can be unreliable. Censuses are expensive and hard to run in developing countries, so figures may be out of date or inaccurate.
Using a range of social and economic indicators, or a composite such as the HDI, gives a more reliable picture.
Examples in context
Example 1. The UK as a developed country. High GNP per person, very low infant mortality, life expectancy over 80 and near-universal literacy place the UK firmly among developed countries.
Example 2. Malawi as a developing country. Low GNP per person, a high birth rate, higher infant mortality and lower life expectancy show the contrasting profile of a developing country and the gap a single indicator cannot fully capture.

SQA N5 style4 marksExplain why a single development indicator may not give a true picture of a country's level of development.Show worked answer →
A 4-mark Explain answer wants developed reasons, so give several distinct problems with relying on one indicator.
A single economic indicator such as GNP per person is an average, so it hides the huge gap between rich and poor within a country: a few very rich people can pull the average up while most live in poverty.
An economic indicator on its own tells you nothing about quality of life, such as health, education or clean water, which can vary even between countries with similar incomes.
Data may be out of date or unreliable, especially in developing countries where censuses are costly and hard to carry out, so one figure may be wrong.
Using a range of social and economic indicators, or a composite measure such as the Human Development Index, gives a fuller, more reliable picture. Markers reward each clear reason (averages hide inequality, one measure ignores quality of life, data can be unreliable) and the point that several indicators are better.
SQA N5 style4 marksDescribe the differences you would expect between a developed and a developing country using named indicators.Show worked answer →
This is a compare question, so each point must contrast both types of country with a named indicator.
A developed country has a high GNP per person, while a developing country has a low GNP per person.
A developed country has a low birth rate and low death rate, while a developing country usually has a high birth rate (and often a higher death rate).
A developed country has high adult literacy and many doctors per person, while a developing country has lower literacy and far fewer doctors per person.
A developed country has low infant mortality and high life expectancy, while a developing country has higher infant mortality and lower life expectancy. Markers reward each named indicator used to contrast both kinds of country; a one-sided point loses the comparison mark.
