Growth versus development
Growth is a change in quantity. It is measured in numbers: more income, more roads, more factories. It can be positive or negative.
Development is a change in quality. It is always positive. It means people live better: they are healthier, better educated and freer.
A city may grow in size and wealth, yet if its people have poor health and no clean water, it has not developed. Growth can happen without development, but development usually needs some growth.
Concept of human development
The idea of human development was put forward by economist Mahbub-ul-Haq and made popular by Amartya Sen. It says the aim of development is to widen people's choices and improve their lives.
Three basic choices matter most: to lead a long and healthy life, to gain knowledge, and to have enough means (income) for a decent life. Without these, people have few real choices.
The United Nations Development Programme (UNDP) has published the Human Development Report every year since 1990.
Four pillars of human development
- Equity: every person gets equal chances, whatever their gender, caste, race or income.
- Sustainability: chances must continue for future generations. We should not use up resources and leave nothing.
- Productivity: people's work should be valuable. Better health and skills make people more productive.
- Empowerment: people should have the power to make their own choices. Good governance and freedom help this.
Approaches to human development
- Income approach: the oldest. More income means more freedom. It looks only at money.
- Welfare approach: the government spends more on education, health and social welfare. People are seen as receivers (beneficiaries).
- Basic needs approach: first meet six basic needs: health, education, food, water supply, sanitation and housing. Given by the International Labour Organisation (ILO).
- Capability approach: build people's capabilities in health, education and access to resources. Linked with Amartya Sen.
Measuring development: HDI, HPI and GNH
Human Development Index (HDI)
It ranks countries on three parts: health (life expectancy at birth), education (years of schooling) and access to resources (income per person, adjusted for prices). Each part gets a score from 0 to 1, and together they give one HDI score from 0 to 1. Closer to 1 means higher development.
Human Poverty Index (HPI)
It measured the shortfall, or what is missing: chance of not living to 40, adult illiteracy, and lack of clean water and healthy food. HDI shows progress; HPI showed deprivation. (UNDP later moved to a broader poverty measure.)
Gross National Happiness (GNH)
Bhutan measures progress by the happiness of its people, not only by production. It includes good governance, culture, environment and well-being. It reminds us that development must not harm nature or culture.
International comparisons
UNDP puts countries into four groups by HDI score:
- Very high (0.800 and above)
- High (0.700–0.799)
- Medium (0.550–0.699) — India is in this group
- Low (below 0.550)
Size and money do not decide the rank alone. Some small countries score very high because they spend well on health and schools. Countries with low scores often have conflict, weak health care, low schooling and gender gaps. Social spending and good governance make a big difference.
Key formulas and definitions
- Growth = change in quantity (can be + or −); development = change in quality (always +)
- Human development = widening people's choices (Mahbub-ul-Haq, Amartya Sen)
- Four pillars: equity, sustainability, productivity, empowerment
- Four approaches: income, welfare, basic needs (ILO, 6 needs), capability (Sen)
- HDI = combines health + education + income index, range 0 to 1 (UNDP uses a geometric mean)
- HDI groups: very high ≥ 0.800; high 0.700–0.799; medium 0.550–0.699; low < 0.550
- HPI = measures shortfall; GNH = Bhutan's happiness measure
Worked examples
1. Country A's income doubled, but its hospitals and schools did not improve. Is this growth or development?
Growth only. Size (income) rose, but quality of life did not.
2. A country's health index is 0.8, education 0.8 and income 0.8. Find its HDI using the geometric mean.
HDI = cube root of (0.8 × 0.8 × 0.8) = 0.8. Very high group starts at 0.800, so it is very high.
3. Health 0.9, education 0.9, income 0.3. Find HDI and explain.
Product = 0.243; cube root ≈ 0.624 (medium). The weak income part pulls the score down even though health and education are strong.
4. A government builds free schools and hospitals and gives food rations. Which approach?
Welfare approach: the government spends on welfare and people receive it.
5. A plan trains women in skills and gives them loans to start work. Which pillar is strongest here?
Empowerment (and productivity): people get power and skills to make their own choices.
6. Country X has HDI 0.62 and country Y has 0.81. Which groups are they in?
X is medium (0.550–0.699); Y is very high (0.800 and above).
Common mistakes
- Using growth and development as the same word. Growth is quantity; development is quality.
- Thinking HDI is just income. It also includes health and education.
- Mixing HDI and HPI. HDI shows achievement; HPI showed what is lacking.
- Saying the capability approach is about government spending. That is the welfare approach; capability is about building people's abilities.
