Development
What does it mean for a country or a person to 'develop'? This Class 10 Economics chapter shows that people have different goals, explains how development is measured through income and beyond, introduces the Human Development Index, and stresses why development must be sustainable.
Learning objectives
- Recognise that people have different development goals.
- Explain per capita income and its limitations.
- Describe the Human Development Index.
- Understand sustainable development.
Key concepts
Different goals, more than income
Different people have different notions of development; what is development for one may not be so for another, and it may even be destructive for someone else. People seek not only higher income but also other goals such as equal treatment, freedom, security and respect. Quality of life depends on a mix of these, not income alone.
Income as a measure
To compare countries, the most common measure is average income or per capita income — the total income of a country divided by its population. The World Bank uses per capita income to classify countries as rich or low-income. However, averages hide differences between people, so income alone is an incomplete measure.
Beyond income: the HDI
Because money cannot buy everything, development is also measured by other indicators of the quality of life, such as health and education. The Human Development Index (HDI), prepared by the UNDP, ranks countries using life expectancy (health), education level, and per capita income together, giving a fuller picture than income alone.
Sustainability of development
Development must be sustainable — it should meet present needs without exhausting resources or harming the environment for future generations. Overuse of groundwater, depletion of natural resources and pollution threaten future development, so resources must be used carefully and renewable alternatives encouraged.
Important formulas
Per capita income
per capita income = total income of country ÷ total population
Key definitions
- Per capita income
- The average income, found by dividing total income by population.
- Human Development Index
- A measure ranking countries by health, education and income.
- Life expectancy
- The average number of years a person is expected to live.
- Sustainable development
- Development that does not harm the needs of future generations.
Solved examples
Q1. How is per capita income calculated?
Solution: Total income of the country divided by its total population.
Q2. Which organisation prepares the Human Development Index?
Solution: The UNDP (United Nations Development Programme).
Q3. Why is average income an incomplete measure?
Solution: It hides inequalities, as it does not show how income is distributed.
Common mistakes to avoid
- Thinking development means only higher income.
- Forgetting that averages hide inequality.
- Confusing per capita income with total income.
- Ignoring sustainability when discussing development.

Long answer
Why is per capita income not a complete measure of development?
Per capita income, the average income found by dividing a country's total income by its population, is the most common measure used to compare countries and is used by the World Bank to classify them. However, it is an incomplete measure for several reasons. Being an average, it hides the differences between people — two countries with the same average income may have very different levels of inequality, and a high average can exist alongside widespread poverty. Moreover, money cannot buy everything that makes life good: a clean and safe environment, good health, education, freedom and respect are also vital, and these are not captured by income. For these reasons, development is also judged by other indicators of the quality of life, such as those in the Human Development Index.
Explain the Human Development Index and the importance of sustainable development.
The Human Development Index (HDI) is a measure prepared by the United Nations Development Programme (UNDP) to compare the development of countries more fully than income alone. It combines three aspects of the quality of life: health, measured by life expectancy at birth; education, measured by literacy and years of schooling; and the standard of living, measured by per capita income. By ranking countries on these together, the HDI gives a broader picture of human well-being. Equally important is the idea that development must be sustainable — it should meet the needs of the present without compromising the ability of future generations to meet their own needs. Overusing resources like groundwater, depleting fossil fuels and damaging the environment can undermine future development, so resources must be used wisely and renewable alternatives promoted.
HOTS (Higher Order Thinking)
Why might the same activity be 'development' for one group and harmful for another?
A dam may bring electricity and irrigation (development) for some, while submerging the land and homes of others, who experience it as destruction — showing that development goals differ between people.
Why can two countries with the same per capita income differ greatly in well-being?
Because the average hides how income is shared and ignores health, education and environment; one country may have wide inequality and poor services despite the same average income.
Quick revision
Revision notes
- People have different goals; development is more than income (freedom, security, respect).
- Per capita income = total income ÷ population; used by World Bank but hides inequality.
- HDI (UNDP): health (life expectancy) + education + income.
- Development must be sustainable — protect resources for the future.
Key takeaways
- Development means more than money.
- Averages hide inequality; HDI gives a fuller picture.
- Development must be sustainable.
Frequently asked questions

Health, education and income together.
Why does development need to be sustainable?
So that present use of resources does not rob future generations.
