Development

PART 1 — Quick Reference Tables

Table 1: Per Capita Income and HDI Comparison — India, Sri Lanka, Myanmar

Note: NCERT table uses older data; current values differ. India's HDI rank in the 2025 UNDP Human Development Report (data for 2023) is 130 out of 193 countries, with an HDI value of 0.685. Sri Lanka ranks 93 with HDI value ~0.78.

Table 2: Human Development Index (HDI) — Components

The HDI combines these three dimensions into a single composite index on a scale of 0 to 1. UNDP classifies countries into: Very High HDI (≥0.800), High HDI (0.700–0.799), Medium HDI (0.550–0.699), Low HDI (<0.550). India is in the Medium HDI category (HDI 0.685 in 2023), approaching the threshold for High HDI.

PART 2 — Chapter Narrative

What Is Development?

Different People, Different Goals

The concept of development is deceptively simple. Development means improvement — but improvement of what, for whom, and measured how? Different people have very different answers.

Consider three people in rural India:

• A landless agricultural labourer wants more days of employment, higher wages, and access to government ration shops to ensure food security.
• A prosperous farmer wants higher prices for her crops, reliable irrigation, and access to markets.
• A young educated woman from a village might want employment in a city, freedom to choose her own career, and independence from family-decided marriage.

All three have legitimate aspirations. All three want development — but they want different things. This simple observation leads to a crucial insight: development goals conflict. The landless labourer wants higher wages; the prosperous farmer-employer wants lower labour costs. The aspiration for higher crop prices conflicts with the aspiration for cheaper food. Development involves trade-offs and choices about whose interests matter more.

This means that development is not a simple technical question ("how do we grow GDP faster?") but a fundamentally political question — about values, priorities, and whose interests govern policy.

Material and Non-Material Aspirations

People want more than just higher income. They want:

• Security — freedom from crime, violence, and arbitrary authority.
• Dignity and respect — not to be humiliated or discriminated against.
• Equality — not to be treated as inferior because of caste, religion, gender, or ethnicity.
• Freedom — to make choices about their own lives.
• Access to public goods — clean water, good roads, quality schools, functioning hospitals.

These aspirations cannot be reduced to income. A person with a good income in a society with pervasive discrimination or insecurity may be worse off in important ways than a poorer person in a more equal, secure society. This is why development economists argue that income is a means to well-being, not an end in itself.

National Development Goals

If individual development goals differ and sometimes conflict, what can we say about national development — the development goals of a country as a whole?

National development goals are the shared or collective aspirations that a society decides to pursue through public policy. In India, these have included:

• Poverty reduction and elimination (Garibi Hatao; MNREGA; PM Garib Kalyan Yojana)
• Universal education (Right to Education Act, 2009)
• Universal healthcare (Ayushman Bharat)
• Infrastructure development (roads, railways, power, digital connectivity)
• Food security (PDS, National Food Security Act, 2013)
• Environmental sustainability (clean energy transition, forest conservation)

The key point is that different people would have different national development priorities — someone who prioritises poverty alleviation may want more spending on social programmes; someone who prioritises economic growth may want more investment in infrastructure and manufacturing; someone who prioritises environmental quality may want stricter regulations on polluting industries.

Democracy is supposed to be the mechanism by which these competing preferences are aggregated into collective decisions. This is why development policy is always contested.

Income and Other Goals

Per Capita Income as a Development Indicator

For decades, economists measured development primarily through per capita income (PCI) — total national income divided by total population. The World Bank historically classified countries by PCI: high-income, middle-income, and low-income countries.

PCI has real advantages as a measure:

• It is easy to calculate.
• It is available for virtually every country.
• It allows comparisons over time and across countries.
• It captures the average material standard of living.

India, Sri Lanka, and Myanmar — three South Asian and Southeast Asian neighbours — illustrate the use of PCI in development comparisons. According to the data the NCERT uses in Class 10 (based on World Development Indicators):

• Sri Lanka has the highest per capita income of the three.
• India is in the middle.
• Myanmar has the lowest per capita income.

Based purely on PCI, Sri Lanka is the most "developed" of the three, India is in the middle, and Myanmar is the least developed.

📌 Key Fact: India's HDI Rank (2025 HDR, data for 2023)

According to the 2025 UNDP Human Development Report — which uses 2023 data — India ranks 130 out of 193 countries, with an HDI value of 0.685. India is in the Medium Human Development category, close to the threshold for High HDI (0.700). Life expectancy in India reached 72 years in 2023 — the highest since the HDI series began. India's HDI has increased by over 53% since 1990, growing faster than both the global and South Asian averages.

Sri Lanka, by contrast, ranks 93 with HDI value ~0.78 — in the High HDI category. This reflects Sri Lanka's superior performance on health and education outcomes, which is captured by the HDI but not by income alone.

Human Development Index (HDI)

Why the HDI Was Created

The Human Development Index was developed by the United Nations Development Programme (UNDP) in 1990, introduced through the first Human Development Report. The key architect of the HDI was Pakistani economist Mahbub ul Haq, working closely with Nobel laureate Amartya Sen (Indian economist).

The HDI was created because economists and policymakers recognised that PCI alone gave a distorted picture of human well-being. A country could have high income but poor health systems, inadequate education, and stark inequality. The HDI was designed to capture a broader, more complete picture of human development.

Mahbub ul Haq's guiding philosophy was that "people are the real wealth of nations." Development should expand human capabilities — the ability to live long, healthy, educated, and fulfilling lives — not merely accumulate material goods.

The Three Dimensions of HDI

The HDI measures a country's average achievements in three fundamental dimensions of human development:

1. Long and healthy life, measured by life expectancy at birth. This captures whether people in a country actually live long lives — which depends on healthcare quality, nutrition, sanitation, environmental conditions, and the absence of violence.

2. Knowledge and education, measured by two indicators:

• Mean years of schooling for adults aged 25 and over — how much education adults in the country have actually received.
• Expected years of schooling for children currently entering school — a forward-looking measure of educational opportunity.

3. A decent standard of living, measured by Gross National Income (GNI) per capita in purchasing power parity (PPP) terms. This ensures that the income comparison accounts for what money can actually buy in different countries.

These three dimensions are combined into a single composite index using a geometric mean. The HDI ranges from 0 (lowest) to 1 (highest).

💡 Explainer: GNI vs GDP

The HDI uses GNI (Gross National Income), not GDP (Gross Domestic Product). The difference:

• GDP = total value of all goods and services produced within a country's borders in a year.
• GNI = GDP + income earned by residents abroad - income earned by foreigners within the country.

For India, GNI is slightly lower than GDP because more money flows out (to foreign investors) than flows in from Indian emigrants' remittances on net. But the difference is modest for most large countries.

Limitations of Per Capita Income

The Kerala vs Punjab Comparison

The most powerful illustration of why PCI is an inadequate development measure comes from within India itself: the comparison of Kerala and Punjab.

Punjab has consistently had a higher per capita income than Kerala. Based on PCI alone, Punjab is more "developed."

But consider other indicators:

• Infant Mortality Rate (IMR): Kerala has one of India's lowest IMR — meaning far fewer children die in infancy. Punjab's IMR is higher.
• Literacy rate: Kerala is among India's most literate states, with literacy rates above 95%. Punjab's literacy rate is lower.
• Life expectancy: Kerala's life expectancy is above the national average; Punjab's is lower than Kerala's.

By HDI-type measures — which capture health and education outcomes alongside income — Kerala consistently ranks among India's top performing states. Punjab, despite higher income, ranks lower on human development.

What explains this paradox? Kerala made significant public investments in health infrastructure and education since the 19th century (through the princely states of Travancore and Cochin and Christian mission schools) and in the post-independence era. These public investments produced widespread literacy, good health indicators, and low fertility — even before Kerala's per capita income rose significantly.

The Kerala model demonstrates that it is possible to achieve high human development at relatively modest income levels, through sustained public investment in health and education. This is sometimes called the "low-income, high-development" model.

🎯 UPSC Connect: Kerala Model

The Kerala model has been widely discussed in development economics. It inspired the HDR's focus on human development rather than economic growth alone. Key features: high female literacy (driving lower fertility and better child health); strong public healthcare system; active civil society and labour movements demanding better social services; progressive land reforms (1957–64 under E.M.S. Namboodiripad's Communist government). Critiques: Kerala also had high unemployment and significant emigration (Gulf migration), suggesting the model has limits for economic employment generation.

Infant Mortality Rate (IMR) and Other Indicators

Infant Mortality Rate

Infant Mortality Rate (IMR) is defined as the number of children who die before completing one year of age per 1,000 live births in a given year. It is one of the most widely used indicators of overall development because it reflects:

• Quality of maternal and child healthcare.
• Access to nutrition and clean water.
• Quality of sanitation.
• Levels of poverty and social deprivation.

A country with high IMR is one where the most vulnerable members of society — newborns — are dying at high rates, indicating failures of healthcare systems, nutrition programmes, and poverty reduction.

India's IMR has fallen dramatically since independence — from approximately 146 per 1,000 in 1960 to around 28 per 1,000 in recent years. But the decline has been uneven across states: Kerala's IMR (around 7) is far below India's average, while Uttar Pradesh and Madhya Pradesh have much higher IMR values.

Net Attendance Ratio (NAR)

Net Attendance Ratio measures the percentage of children in the relevant age group who are actually attending school. It is distinct from the gross enrolment ratio (which counts all enrolled students regardless of age) and captures whether the target age group is actually receiving education.

Low NAR in secondary schools — particularly for girls — indicates educational exclusion, often driven by poverty, social norms, lack of nearby schools, and the opportunity cost of girls' time (domestic work, early marriage).

📌 Key Fact: India's Educational Progress

India achieved near-universal primary enrolment — the NAR for primary school (classes 1–8) has been above 95% for several years, following the Sarva Shiksha Abhiyan and the Right to Education Act (2009). However, secondary and higher education NAR remains lower, particularly for girls in rural areas, tribal communities, and Muslim minorities.

Sustainability of Development

The Problem of Unsustainable Growth

A central question in development economics is: can today's growth be maintained in the future? High income today may be generated by extracting and depleting natural resources — forests, minerals, groundwater, fossil fuels — that cannot be renewed at the same rate. When these resources are exhausted, future generations will have less to work with.

This is the problem of sustainability. Development is sustainable only when it meets the needs of the present generation without compromising the ability of future generations to meet their needs. This definition comes from the 1987 Brundtland Commission Report ("Our Common Future").

Examples of Unsustainable Development

Overuse of groundwater: Many states in India — particularly Punjab, Haryana, and parts of Rajasthan — are overextracting groundwater for irrigation. The water table is falling rapidly. If this continues, future generations will face severe water scarcity in these agricultural regions.

Deforestation: Clearing forests for agriculture, mining, or infrastructure generates income today but destroys biodiversity, disrupts water cycles, and releases carbon. Once a forest ecosystem is degraded beyond a threshold, it cannot easily recover.

Fossil fuel extraction: Coal, oil, and natural gas generate enormous income but are non-renewable. Burning them also causes climate change, which will impose enormous costs on future generations (flooding, droughts, crop failures, sea-level rise).

The Environment-Development Tension

Sustainable development requires balancing economic growth with environmental protection. This is a central tension in development policy:

• Economic growth typically involves increasing energy use, industrialisation, and natural resource extraction.
• Environmental sustainability requires limiting pollution, protecting ecosystems, and transitioning to renewable energy.

India's rapid economic growth since the 1990s has been accompanied by significant environmental costs: air pollution, water pollution, deforestation, and carbon emissions. India's National Action Plan on Climate Change (NAPCC, 2008) and commitments under the Paris Agreement (2015) represent attempts to pursue growth while managing environmental costs.

💡 Explainer: Why Sustainability Matters for UPSC

"Sustainable development" is a core concept in UPSC GS3 (Economy and Environment). The tension between growth and sustainability appears in questions on natural resource management, environmental impact assessment, climate policy, forest rights, and tribal displacement. The concept connects Economics (this chapter) to Environment (GS3 Environment and Ecology section). Key terms: Brundtland Commission definition (1987), intergenerational equity, non-renewable vs renewable resources, green GDP.

Comparison of Countries: Beyond Income

Why Income Comparison Is Insufficient

When we compare countries like India, China, the United States, and Sri Lanka, income statistics tell only part of the story. Countries with similar incomes can have very different outcomes on:

• Health (life expectancy, child mortality)
• Education (literacy rates, years of schooling)
• Inequality (how income is distributed)
• Gender equality (women's education, employment, political representation)
• Freedom and human rights

Cuba and Saudi Arabia are two countries that illustrate this:

• Both have moderate income levels.
• Cuba has high literacy and good healthcare (HDI better than its income level would suggest).
• Saudi Arabia has high income from oil but historically lower female education and employment.

China and India provide another instructive comparison:

• China has significantly higher per capita income than India.
• China also performs better on most health and education indicators — lower IMR, higher life expectancy, near-universal literacy.
• But China also has less political freedom and more environmental pollution.

The point is that no single measure captures everything that matters for human well-being. The HDI tries to capture three key dimensions (health, education, income), but even the HDI misses gender equality, inequality, freedom, and sustainability.

🎯 UPSC Connect: Multidimensional Poverty Index (MPI)

The Multidimensional Poverty Index (MPI) — developed by UNDP and the Oxford Poverty and Human Development Initiative (OPHI) — is an extension of the HDI idea. It measures deprivation across 10 indicators in three dimensions: education, health, and living standards. A person is counted as "multidimensionally poor" if they are deprived in at least one third (weighted) of the indicators. India's National MPI (released by NITI Aayog) tracks multidimensional poverty at the state level. This is frequently referenced in UPSC Mains answers on poverty measurement.

PART 3 — Frameworks and Mnemonics

Mnemonic: HDI's 3 Dimensions — "HEI"

H = Health — measured by Life expectancy at birth E = Education — measured by Mean years of schooling + Expected years of schooling I = Income — measured by GNI per capita (PPP)

Published by: UNDP (United Nations Development Programme) Created by: Mahbub ul Haq (Pakistan) with Amartya Sen (India) First published: 1990 India's rank: 130 out of 193 (2025 HDR, data for 2023); HDI value: 0.685; Category: Medium HDI

Mnemonic: Development Indicators — "PILMER"

P = Per Capita Income (average material standard of living) I = Infant Mortality Rate (child survival; reflects healthcare and sanitation) L = Literacy Rate (access to education; human capital) M = Maternal Mortality Rate (healthcare quality for women) E = Expected/Mean years of schooling (education depth) R = Net Attendance Ratio (actual school attendance)

Framework: Kerala Model vs Punjab Model — 3 Contrasts

Lesson: Income ≠ Human Development. Public investment in health and education can produce high human development even at lower income levels.

Framework: Why PCI Fails as the Sole Development Measure — "INDSEC"

I = Ignores inequality (average can hide vast gaps between rich and poor) N = Non-material aspects ignored (health, education, security, dignity, freedom) D = Doesn't capture sustainability (high income today may deplete resources for tomorrow) S = Sampling issues with currency conversion (needs PPP adjustment for valid comparison) E = Environmental costs invisible in PCI (pollution-generating industries boost PCI) C = Contribution of women's unpaid work not counted

Framework: Sustainable Development — Brundtland Definition

"Development that meets the needs of the present without compromising the ability of future generations to meet their own needs." — Brundtland Commission, 1987

Key concept: Intergenerational equity — we have obligations to future generations, not just to present populations.

India's non-renewable resource challenges for UPSC:

• Groundwater depletion (Punjab, Haryana, Rajasthan)
• Coal and fossil fuel dependence
• Deforestation
• Biodiversity loss

• HDI created by Mahbub ul Haq (with Amartya Sen); first published 1990; published by UNDP.

Mains — Three High-Value Themes:

1. Why development cannot be measured by income alone — Use the PCI limitations framework (INDSEC). Illustrate with Kerala-Punjab comparison (Table 4) and India-Sri Lanka HDI comparison (Table 1). Argue for a multidimensional view of development capturing health, education, inequality, and sustainability. Mention HDI and MPI as better measures.

2. Human Development Index — concept, components, significance — Explain the intellectual background (Mahbub ul Haq, Amartya Sen, 1990 UNDP). List the three dimensions (HEI mnemonic). Discuss India's HDI rank (130/193, 2025 HDR). Compare India with Sri Lanka. Assess HDI's strengths (combines income, health, education) and weaknesses (doesn't capture inequality, gender gaps, freedom, sustainability).

3. Sustainable development — concept and India's challenges — Define using Brundtland (1987). Explain intergenerational equity. Give India-specific examples of unsustainable resource use: groundwater depletion, fossil fuel dependence, deforestation. Connect to NAPCC (2008) and Paris Agreement. Argue that India's development model must transition to sustainable pathways — not just for environmental reasons but because unsustainable growth will eventually lower PCI and human development outcomes for future generations.

Previous Year Questions (PYQs)

Prelims

Q1. The Human Development Index (HDI) is published by:

• (a) World Bank
• (b) International Monetary Fund
• (c) United Nations Development Programme (UNDP)
• (d) World Economic Forum

Answer: (c) — The HDI is published annually by UNDP in its Human Development Report. It was first introduced in 1990 by Pakistani economist Mahbub ul Haq (with input from Amartya Sen).

Q2. Which of the following is NOT a component of the Human Development Index (HDI)?

• (a) Life expectancy at birth
• (b) Per capita income (GNI per capita, PPP)
• (c) Infant Mortality Rate
• (d) Expected years of schooling

Answer: (c) — The HDI's three components are: (1) Life expectancy at birth; (2) Education (mean years + expected years of schooling); (3) GNI per capita, PPP. Infant Mortality Rate is an important development indicator but is NOT one of the three components of the HDI formula.

Q3. Consider the following statements about the "Kerala model" of development:

1. Kerala has lower per capita income than Punjab but better health indicators.
2. Kerala's infant mortality rate is among India's lowest.

Which of the above is/are correct?

• (a) 1 and 2 only
• (b) 2 and 3 only
• (c) 1 only
• (d) 1, 2, and 3

Answer: (a) — Statements 1 and 2 are correct. Statement 3 is incorrect — the Kerala model demonstrates the opposite: that it is possible to achieve good human development at relatively lower income levels, through public investment in health and education. Income does not necessarily lead to better human development.

Q4. "Development that meets the needs of the present without compromising the ability of future generations to meet their own needs" is the definition of sustainable development given by:

• (a) The Kyoto Protocol (1997)
• (b) The Brundtland Commission Report "Our Common Future" (1987)
• (c) The Stockholm Declaration (1972)
• (d) The Rio Earth Summit Declaration (1992)

Answer: (b) — This definition comes from the Brundtland Commission Report ("Our Common Future"), formally the World Commission on Environment and Development, chaired by Norwegian PM Gro Harlem Brundtland, published in 1987.

Mains

Q1. "Per capita income is a necessary but insufficient measure of development." Discuss with reference to the Kerala model and the concept of Human Development. (150 words)

Approach: Explain what per capita income measures and its advantages (easy to calculate, comparable across countries). List its limitations (ignores inequality, non-material aspects, sustainability, environmental costs — use INDSEC framework). Illustrate with Kerala-Punjab comparison: Punjab has higher PCI but worse IMR and lower literacy; Kerala achieves high human development through sustained public investment in health and education. Introduce HDI as a better measure: three dimensions (HEI mnemonic). State India's HDI rank (130/193, 2025 HDR). Conclude: development means expanding human capabilities — health, education, and material well-being together — not just income growth.

Q2. What do you understand by sustainable development? Identify at least two ways in which current patterns of resource use in India are unsustainable. (150 words)

Approach: Define sustainable development using the Brundtland definition (1987) — meeting present needs without compromising future generations. Explain the concept of intergenerational equity. Identify two Indian examples: (1) Groundwater depletion — Punjab, Haryana, and Rajasthan are overextracting groundwater for agriculture; the water table is falling, threatening future agricultural viability; (2) Coal dependence — India remains heavily dependent on coal for electricity generation; coal is non-renewable and its combustion contributes to climate change that will impose costs on future generations. Additional examples possible: deforestation; biodiversity loss; industrial pollution of rivers. Connect to India's policy responses: NAPCC 2008, renewable energy targets (solar/wind), Paris Agreement NDCs, National Green Hydrogen Mission. Conclude: sustainable development is not a constraint on growth but a prerequisite for long-term growth — unsustainable resource use eventually undermines the productive base of the economy.
