Different People, Different Goals Landless Worker More work days Better wages Good school for kids Prosperous Farmer High crop prices Cheap labour Children educated Urban Girl Equal freedom Study abroad Choose own career Adivasi (Tribal) Land rights No displacement Cultural identity Key Idea: Goals differ based on life situation What helps one group may harm another group National Development = Fair path that benefits the most people

Different people have different development goals.

Average Income: What It Hides Country A — Equal Society Citizens earn: 9500, 10500, 9800, 10000, 10200 Average = Rs 10,000 Nobody is very rich or very poor Everyone earns close to average MORE DESIRABLE Country B — Unequal Society Citizens earn: 500, 500, 500, 500, 48000 Average = Rs 10,000 (SAME!) 4 citizens are very poor 1 citizen is extremely rich LESS DESIRABLE

Same average income can hide very different levels of inequality.

Kerala vs Haryana — Income vs Quality of Life State Per Capita Income IMR (per 1000) Literacy Rate % Haryana Rs 3,25,759 (HIGH) 28 (POOR) 82% Kerala Rs 2,81,001 (LOWER) 6 (EXCELLENT) 94% (BEST) KEY LESSON: Higher income alone does NOT mean better development Kerala shows better human development despite lower income than Haryana

Per capita income is not enough — health and education matter too.

HDI: Three Pillars of Human Development 🏥 HEALTH Life Expectancy How long people live Infant Mortality Rate 📚 EDUCATION Mean Years of Schooling Literacy levels School attendance 💰 INCOME Gross National Income Per capita (PPP $) Purchasing power

HDI by UNDP combines health, education, and income. India ranks 130 (out of 193).

Sustainable vs Unsustainable Development SUSTAINABLE ✓ Use renewable resources wisely Solar / wind energy Protect forests and groundwater Future generations can also develop UNSUSTAINABLE ✗ Overuse groundwater (300 districts declining) Burn crude oil rapidly (runs out in ~47 yrs) Cut forests for quick profit Future generations suffer

Sustainable development meets today's needs without harming the future.

✏️ Section 3: Worked Examples

📖 Question 1: Country A has 5 citizens earning Rs 4000, Rs 7000, Rs 3000, Rs 6000 and ?. The average per capita income is Rs 5000. Find the income of the fifth person.
1 Add known incomes: 4000 + 7000 + 3000 + 6000 = 20,000
2 Total income needed: 5000 × 5 = 25,000
3 Fifth person's income: 25,000 − 20,000 = Rs 5,000
Answer: The fifth person earns Rs 5,000. This is a balanced country where no one is extremely rich or poor.
📖 Question 2: Haryana has higher per capita income than Kerala. Yet Kerala has a much lower Infant Mortality Rate. Why?
1 Kerala spends more on public healthcare and education.
2 Public Distribution System (PDS) works well in Kerala.
3 Money in your pocket cannot buy collective public services.
4 Clean water, hospitals, and schools reduce infant deaths.
Answer: Public facilities (hospitals, PDS, schools) matter more than just income. Kerala proves income alone does not determine human well-being.
📖 Question 3: Why is groundwater over-use called unsustainable development?
1 Groundwater is a renewable resource — rain refills it slowly.
2 About 300 Indian districts show water level falling over 4 metres.
3 If extraction exceeds rainfall refill, water will be permanently lost.
4 Future farmers will have no water for crops.
Answer: Using groundwater faster than nature can replenish it harms future generations. This is unsustainable because it sacrifices tomorrow for today's gain.
📖 Question 4: How is the World Bank's measure of development different from UNDP's HDI?
1 World Bank uses only per capita income to rank countries.
2 UNDP uses three factors: income + health + education.
3 HDI gives a fuller picture of actual human well-being.
4 A country can have high income but poor HDI if health/education is neglected.
Answer: World Bank's single-income method is simpler but incomplete. UNDP's HDI is more holistic as it measures people's actual capabilities, not just money.

🏠 Section 5: Take-Home Handout — Practice Questions

Q1. A family has five members. Their monthly incomes are Rs 2000, Rs 5000, Rs 3000, Rs 4000, and Rs 6000. What is the average (per capita) income? Does this average tell you how equally the income is shared?
Q2. Sri Lanka has a higher HDI rank than India even though India is a larger country. List three reasons why Sri Lanka might have a better HDI rank.
Q3. A big company wants to build a factory near a forest. The factory will create 2000 jobs but will cut down 50,000 trees. Is this development? Argue from TWO different perspectives.
Q4. Explain how Kerala achieved low infant mortality despite having lower per capita income than Haryana. What does this teach us about development?
Q5. "Groundwater is a renewable resource, yet it can be over-used." Explain this statement with an example and say how India should tackle this problem.

Answers to Practice Questions

A1. Total income = 2000+5000+3000+4000+6000 = 20,000. Average = 20,000 ÷ 5 = Rs 4,000. The average hides inequality. The person earning Rs 6000 is 3 times richer than the one earning Rs 2000. Averages are useful for comparison but do not show how fairly income is distributed.
A2. Sri Lanka has better HDI because: (a) Life expectancy is 77.5 years vs India's 72 years, showing better healthcare. (b) Mean years of schooling is 10.8 vs India's 6.9, showing better education. (c) Public services like hospitals and schools are more accessible in Sri Lanka. HDI is about people's well-being, not just national size or wealth.
A3. From a job-seeker's view: The factory is development — 2000 families get income, taxes are paid, the economy grows. From an Adivasi/forest-dweller's view: This is destruction — forest livelihood is lost, biodiversity is damaged, and the displaced community has no benefit. This example shows development for one can be destruction for another.
A4. Kerala achieved low IMR (6 per 1000) through: (a) Strong network of government hospitals and Primary Health Centres. (b) Effective Public Distribution System (PDS) ensuring food and nutrition. (c) High female literacy — educated mothers take better care of infants. Lesson: Public investment in health and education can deliver better human development than just increasing average income.
A5. Groundwater is renewable because rainfall refills it. But if we pump out water faster than rainfall can replace, the water table falls permanently. In India, about 300 districts already have falling water levels. Punjab and Western UP are worst affected due to intensive agriculture. Solutions: Adopt drip irrigation, rainwater harvesting, reduce water-intensive crops like paddy in water-scarce areas, and enforce groundwater use limits.
