💡 What is Development?
- Development = progress + improvement in quality of life.
- People have different developmental goals based on their life situations.
- What is development for one may be harmful for another (conflicting goals).
- Development is not just income — includes freedom, equality, security, respect.
- Decisions involve trade-offs between different stakeholders.
Key Example: A dam = electricity for industry BUT displacement for tribals. Both are valid developmental concerns.
💰 National Income & Per Capita Income
- National Income: Total value of goods & services produced in a country/year.
- Per Capita Income (PCI):
PCI = National Income ÷ Total Population
- Used by World Bank to classify countries.
- Limitation: It's an average — hides inequality!
- High PCI ≠ everyone is well-off (wealth may be concentrated).
World Bank Classification (2019)
| Category | PCI Threshold |
|---|
| Rich (High-income) | > $12,056/year |
| Upper middle-income | $3,996 – $12,055 |
| Lower middle-income | $1,036 – $3,995 |
| Low-income | < $1,036/year |
India = Low middle-income country (PCI ≈ $6,681 PPP)
📊 Key Development Indicators
| Indicator | What it Measures | Formula / Definition | Better = ? |
|---|
| IMR | Child health & healthcare | Deaths before age 1, per 1000 live births | Lower |
| Literacy Rate | Education access | % of pop. age 7+ who can read & write | Higher |
| NAR | School attendance | % of age-group children actually in school | Higher |
| Life Expectancy | Overall health | Average years a newborn is expected to live | Higher |
| BMI | Nutrition status | Weight(kg) ÷ Height²(m²) | 18.5–24.9 |
🗺️ Comparing Indian States
| Indicator | Kerala | Punjab | Bihar |
|---|
| Per Capita Income | ₹1,50,000 | ₹2,10,000 ✓ | ₹40,000 |
| IMR (per 1000) | 7 ✓ | 25 | 38 |
| Literacy Rate | 94% ✓ | 82% | 62% |
| Net Attendance | 83% ✓ | 79% | 43% |
| Life Expectancy | 75 yrs ✓ | 72 yrs | 65 yrs |
Conclusion: Punjab = richest but Kerala = most developed. Income alone ≠ Development!
🏆 Human Development Index (HDI)
- Published by UNDP annually.
- Scale: 0 (worst) to 1 (best).
- More comprehensive than World Bank's income-only approach.
Three Pillars of HDI
| Pillar | Indicator Used |
|---|
| ❤️ Health | Life Expectancy at Birth |
| 📚 Education | Mean Years of Schooling + Expected Years |
| 💵 Standard of Living | GNI per capita (PPP $) |
Country Comparison
| Country | HDI Rank | Life Exp. | Schooling | GNI/cap |
|---|
| Sri Lanka | 72 | 77 yrs | 10.6 yrs | $12,707 |
| India | 131 | 69 yrs | 6.5 yrs | $6,681 |
| Pakistan | 154 | 67 yrs | 5.2 yrs | $5,005 |
⚖️ World Bank vs UNDP
| Feature | World Bank | UNDP |
|---|
| Measure | Per Capita Income only | HDI (3 pillars) |
| Classifies as | Rich / Poor countries | Very High / High / Medium / Low HDI |
| Advantage | Simple, easy to calculate | Holistic, captures quality of life |
| Limitation | Ignores health & education | More complex to compute |
Board favourite: "UNDP method is better because it doesn't look at income alone — it considers what money can and cannot buy."
♻️ Sustainable Development
- Definition: Development that meets present needs without compromising future generations' ability to meet their needs.
- Source: Brundtland Commission, 1987
- Environmental degradation = anti-development.
- Must balance economic growth with environmental protection.
Resource Classification
| Renewable ✅ | Non-Renewable ❌ |
|---|
| Solar, Wind, Hydro, Biomass | Coal (~200 yrs), Petroleum (~50 yrs) |
| Can be replenished naturally | Finite — once gone, gone forever |
| Clean, low pollution | Causes pollution & climate change |
India examples: Groundwater depletion (Punjab), Delhi air pollution, Ganga pollution, deforestation for mining.
🚫 What Money Cannot Buy
- Pollution-free environment — requires collective action
- Freedom & democracy — political, not purchasable
- Respect & dignity — social equality needed
- Peace & security — community-level effort
- Public healthcare for all — market fails the poor
Key insight: These require government intervention and public facilities. The market alone cannot ensure development for all.
🍽️ BMI — Nutritional Indicator
BMI = Weight (kg) ÷ Height² (m²)
| BMI Range | Status | Development Implication |
|---|
| < 18.5 | Undernourished | Poverty, food insecurity |
| 18.5 – 24.9 | Normal | Adequate nutrition |
| 25 – 29.9 | Overweight | Lifestyle concerns |
| ≥ 30 | Obese | Health risk |

🔑 Key Differences & Comparisons
Economic Growth vs Development
| Economic Growth | Development |
|---|

Developed vs Developing Countries
| Developed | Developing |
|---|
| High PCI (>$12,056) | Low/Medium PCI |
| High HDI (>0.8) | Medium/Low HDI |
| Low IMR, High Literacy | Higher IMR, Lower Literacy |
