- distinguish economic growth from development
- evaluate living-standard indicators
- analyse population structure and change
- explain poverty, inequality and development policies
AT A GLANCE
INTRODUCTION · THE BIG IDEA
Compare living standards, population change, poverty and development strategies.
Development is broader than producing more. It concerns health, education, opportunity, security and the ability to meet needs, so no single indicator gives a complete picture.
Population change both affects and responds to development through the labour force, dependency, public services, saving and migration.
SECTION 01
Living standards and development indicators
Real GDP per head estimates average material output, but hides distribution, informal activity, leisure and environmental damage. The Human Development Index combines income per head, life expectancy and education indicators.
Other evidence includes infant mortality, literacy, access to clean water, nutrition, doctors, housing and poverty rates. International comparisons require common definitions, reliable data and purchasing-power differences.
| Indicator | Shows | Misses |
|---|---|---|
| Real GDP per head | average real output/income | distribution and quality of life |
| Life expectancy | health outcomes | income and education directly |
| HDI | broader combined view | inequality and environment in detail |
SECTION 02
Population change and structure
Population changes through births, deaths, immigration and emigration. Birth rates often fall with education, urbanisation, lower infant mortality, female employment and access to family planning. Death rates fall with nutrition, sanitation and healthcare.
An ageing population may increase pension and healthcare pressure and reduce the workforce share, but older people also work, save and consume. A youthful population raises education needs but can create a future demographic dividend if productive jobs exist.
Dependency ratio
- A country has 18 million dependants and 42 million working-age people.
- Ratio = 18 ÷ 42 × 100%.
- Interpret as dependants per 100 working-age people.
Answer: Dependency ratio ≈ 42.9%.
SECTION 03
Poverty and income distribution
Relative poverty means income well below the typical standard in a society. Poverty can result from unemployment, low wages, poor health, limited education, discrimination, weak infrastructure or conflict and can reproduce itself across generations.
Income inequality can be reduced through progressive taxes, benefits, minimum wages, education, healthcare and asset access. Redistribution may improve opportunity and demand but can carry tax cost or weaken some incentives if badly designed.
SECTION 04
Development strategies and sustainability
Development can be supported by education, healthcare, infrastructure, property rights, financial access, diversification, technology, foreign investment, aid and trade. Effectiveness depends on governance, targeting and local conditions.
Foreign direct investment can bring capital, jobs, skills and exports but may repatriate profit or exploit weak standards. Aid can fund urgent needs and public goods but may create dependency, debt or donor influence. Sustainable development meets current needs without reducing future generations' ability to meet theirs.
| Strategy | Potential gain | Risk |
|---|---|---|
| Education | human capital and mobility | long time lag |
| Infrastructure | lower business cost and connect markets | large finance and maintenance need |
| FDI | capital, jobs and technology | profit outflow and weak linkages |
| Aid | fills resource and emergency gaps | dependency or poor targeting |
QUICK CHAPTER SUMMARY
The ideas to carry forward
- Development includes health, education and opportunity, not only output.
- Use several indicators and explain their limits.
- Population structure changes public-service and labour-market needs.
- Development strategies depend on institutions, targeting and sustainability.
