Poverty &
Inequality
What is Poverty?
The Why — Why Define Poverty?
Poverty isn't just about not having money. The way you define poverty determines who gets welfare, which policies are made, and how success is measured. An incorrect definition means crores of people are excluded from welfare.
A state in which an individual or household lacks the financial, material, and social resources necessary to sustain a minimum acceptable standard of living as defined by a given society at a given time.
Types of Poverty
🔴 Absolute Poverty
Below a fixed minimum threshold regardless of where you live. E.g., World Bank's $2.15/day (2017 PPP) poverty line. It is the same for everyone globally.
What: You cannot meet basic survival needs — food, shelter, clothing.
Why used: Helps compare across countries and time periods.
🟣 Relative Poverty
Below a level relative to the median income of a society. Common in developed countries — e.g., EU uses 60% of median disposable income.
What: You are poor compared to others around you.
Why used: Captures social exclusion and inequality within a society.
- Chronic Poverty: Persistent poverty over time — structural, passed through generations. Linked to caste, location, disability. E.g., Scheduled Tribes in forest areas.
- Transient Poverty: Temporary poverty due to shocks — crop failure, illness, job loss. Can be addressed through social safety nets.
Nobel laureate Amartya Sen redefined poverty as deprivation of capabilities — the inability to live a life one has reason to value. It goes beyond income to include functionings like being well-nourished, having self-respect, and participating in community life.
"Poverty is not just a lack of money; it is the lack of capability to live a decent life." — Amartya Sen, Development as Freedom (1999)
UNDP's older measure (replaced by MPI). HPI-1 for developing countries measured: % not expected to survive age 40, adult illiteracy rate, % without access to safe water + health services + underweight children. HPI-2 for developed countries added social exclusion.
How Poverty is Measured
The Headcount Ratio (H) — Most Basic Measure
What it tells you: The percentage of population below the poverty line. Simple, but it doesn't tell you how poor the poor are.
Limitation: Gives equal weight to someone barely below the poverty line and someone in extreme destitution.
Poverty Gap Index (PGI) — Depth of Poverty
Where z = poverty line, yᵢ = income of poor person i, n = total population. Measures the average shortfall from the poverty line as a proportion.
What it tells you: How much money is needed to bring all poor people up to the poverty line.
Foster-Greer-Thorbecke (FGT) Index — Most Comprehensive
- When α=0 → Headcount Ratio (incidence)
- When α=1 → Poverty Gap Index (depth)
- When α=2 → Poverty Severity Index (inequality among the poor)
Higher α gives more weight to the poorest of the poor — this is called the severity of poverty.
| Measure | What it Captures | Limitation |
|---|---|---|
| Headcount Ratio | Who is poor (incidence) | Ignores depth & severity |
| Poverty Gap | How poor (depth) | Doesn't capture inequality among poor |
| FGT P2 | Inequality among poor (severity) | Complex to communicate |
| MPI | Multiple dimensions | Subjective indicator selection |
| HDI | Human development overall | Masks intra-group inequality |
Poverty Lines in India — A History
Evolution of India's Poverty Line
| Committee / Body | Year | Methodology | Key Finding |
|---|---|---|---|
| Dadabhai Naoroji | 1901 | "Drain of Wealth" — poverty as colonial extraction. First attempt to quantify poverty. | Introduced the concept of a "poverty line" in India |
| NSSO + Planning Commission | 1962 | Calorie-based: 2400 kcal (rural), 2100 kcal (urban) | First official poverty line |
| Alagh Committee | 1979 | Minimum nutritional requirement approach | Formalized calorie-based line |
| Lakdawala Committee | 1993 | Consumer Price Index (CPI-AL for rural, CPI-IW for urban). State-specific poverty lines. | Long used official method |
| Tendulkar Committee | 2009 | Shifted from calorie-norms to consumption expenditure. Included health & education spending. Uniform urban line extended to rural. | 21.9% poor (2011-12). Controversial — seen as too low. |
| Rangarajan Committee | 2014 | Monthly per capita expenditure: ₹972 (rural), ₹1407 (urban). Revised upward. | 29.5% poor (2011-12) — 363 mn people |
| World Bank Line | 2022 | $2.15/day (2017 PPP) — international extreme poverty line | Revised from $1.90/day in 2022 |
| World Bank (New) | 2024 | $3.00/day (2021 PPP) — revised to reflect updated purchasing power | India's poverty % fluctuated with this revision |
The World Bank's Updated Poverty Lines (2024)
- $2.15/day (2017 PPP) — Old extreme poverty line for LICs
- $3.00/day (2021 PPP) — New international extreme poverty line (revised May 2024)
- $3.65/day (2017 PPP) — Lower-middle-income country line
- $6.85/day (2017 PPP) — Upper-middle-income country line
Multidimensional Poverty Index (MPI) — Deep Dive
What is MPI and Why?
Income/consumption-based poverty lines have a fatal flaw: a household can be just above the monetary poverty line but still be deprived of schooling, clean water, and healthcare. MPI captures this multidimensional reality.
Developed by Sabina Alkire and James Foster at OPHI (Oxford Poverty and Human Development Initiative) in 2010. Adopted by UNDP for the Human Development Report. MPI = H × A where:
- H = Incidence (% of people who are MPI poor — deprived in 33%+ of weighted indicators)
- A = Intensity (average share of deprivations among MPI-poor people)
The 3 Dimensions, 10 Indicators, 12 Indicators (India)
| Dimension (Weight) | Indicator | Deprived If… |
|---|---|---|
| Health (1/3) | Nutrition | Any adult/child undernourished |
| Child & Adolescent Mortality | Any child (under 18) died in household | |
| Maternal Health | No institutional delivery or ANC visit (India-specific) | |
| — (Global MPI has 3 health indicators) | — | |
| Education (1/3) | Years of Schooling | No HH member completed 6 years of schooling |
| School Attendance | Any school-age child not attending school | |
| — (India adds quality-of-education elements) | — | |
| Living Standards (1/3) | Cooking Fuel | Uses solid/dirty cooking fuel |
| Sanitation | No improved sanitation facility or shared | |
| Drinking Water | No safe drinking water within 30-min walk | |
| Electricity | No electricity | |
| Housing | Inadequate floor/roof/walls | |
| Assets | Owns fewer than 2 small assets or no large asset |
Key Finding: 1.1 billion people across 109 countries live in multidimensional poverty globally. India's MPI value is 0.069 (2025). The 2025 Global MPI report, for the first time, mapped climate hazards against poverty data — 887 million poor people live in areas facing at least one major climate hazard.

Rural vs. Urban Poverty
Between 2015–16 and 2019–21: Rural poverty fell from 32.59% → 19.28% (drop of 13.31 pp). Urban poverty fell from 8.65% → 5.27% (drop of 3.38 pp). Rural areas saw a significantly larger decline, driven by PMAY-G, Jal Jeevan Mission, Ujjwala Yojana, and SBM-G.
Rate of Decline
Highest Deprivation Areas (2005–06)
- Cooking Fuel deprivation: 74.40% (highest)
- Sanitation deprivation: 70.92%
- Bank accounts: 58.11%
- Child mortality deprivation: 4.84% (lowest)
Under the new World Bank poverty line of $3/day (2021 PPP), India's extreme poverty rose statistically to 27.12% (34.47 crore). However, India's updated HCES 2022–23 data showed actual consumption improvement. At the $3.65/day lower-middle-income line, poverty dropped from 61.8% to 28.1% over 2011–12 to 2022–23 (37.8 crore lifted).
Inequality — Concepts & Types
What is Inequality? (What, Why, How)
Unequal distribution of income, wealth, opportunities, and capabilities among individuals or groups. It is both outcome inequality (unequal results) and opportunity inequality (unequal starting positions). Inequality ≠ poverty — a society can be unequal even if no one is poor.
Types of Inequality in India
| Type | Description | Example in India |
|---|---|---|
| Income Inequality | Unequal distribution of earnings | Top 1% earns 22% of national income; bottom 50% earns only 13% |
| Wealth Inequality | Unequal distribution of assets | Top 1% owns ~40% of total wealth |
| Caste Inequality | Social hierarchy limiting opportunities | SC/ST face wage discrimination, land deprivation |
| Gender Inequality | Unequal outcomes by gender | Gender Pay Gap, Female LFPR just ~27% vs male ~80% |
| Regional Inequality | Development gap between states/regions | GSDP per capita: Goa ~₹6L vs Bihar ~₹60K |
| Rural-Urban Inequality | Gap between rural and urban living standards | Rural incomes ~40% lower than urban |
| Educational Inequality | Unequal access to quality education | Elite private schools vs no-teacher schools in rural areas |
| Digital Inequality | Unequal access to internet & digital tools | Urban internet penetration 67% vs rural 31% |
Horizontal vs. Vertical Inequality
Vertical Inequality
Inequality between individuals regardless of group identity. Measured by Gini coefficient, income shares. The traditional economic concept.
Horizontal Inequality
Inequality between culturally defined groups — caste, religion, gender, ethnicity. Critical in India's context. Can fuel social conflict (Stewart, 2000).
Why Does Inequality Matter?
- Economic: Reduces aggregate demand (poor have higher marginal propensity to consume). Stunts human capital formation. Creates rent-seeking.
- Social: Erodes social trust. Increases crime. Perpetuates inter-generational poverty traps.
- Political: Fuels populism, instability. Rich can "capture" democracy — policy bias toward elite interests.
- Health: Wilkinson & Pickett showed in "The Spirit Level" that more unequal societies have worse health outcomes even among the rich.
- SDGs: Goal 10 — Reduce inequality within and among countries. Inequality is both a cause and consequence of poverty.
Gini Coefficient & Lorenz Curve
Lorenz Curve — The Visualisation of Inequality
Developed by Max Otto Lorenz in 1905. It plots the cumulative share of income against the cumulative share of population (ranked from poorest to richest).
- The diagonal line (45°) = line of perfect equality (bottom 40% earn 40% of income)
- The curved line below = actual income distribution (the further below, the more unequal)
- The area between them = basis for Gini coefficient
Gini Coefficient — The Inequality Measure
Where A = area between the line of equality and the Lorenz curve; B = area below the Lorenz curve.
- G = 0 → Perfect equality (everyone earns the same)
- G = 1 → Perfect inequality (one person earns everything)
- G = 0.25–0.35 → Low inequality (Nordic countries)
- G = 0.35–0.45 → Moderate inequality (most developing nations)
- G > 0.50 → High inequality (South Africa: 0.63, worst globally)
India's Gini — The Paradox
Limitations of the Gini Coefficient
- Same Gini can result from very different income distributions (the "Gini imprecision")
- Doesn't capture where in the distribution the inequality occurs
- Sensitive to how income is measured (consumption vs income vs wealth)
- Doesn't capture non-monetary dimensions of inequality
- Cross-country comparisons difficult due to different survey methodologies
Other Inequality Measures
| Measure | Formula/Method | Best For |
|---|---|---|
| Palma Ratio | Top 10% income share ÷ Bottom 40% share | Captures extremes; used by OECD |
| Theil Index | Based on entropy; decomposes within/between group inequality | Inter-group analysis |
| Atkinson Index | Inequality-aversion parameter (ε) | Normative analysis (how much do we care about inequality?) |
| Decile Ratio | Income of top 10% ÷ Income of bottom 10% | Simple, intuitive |
| HDI adjusted for Inequality (IHDI) | Discounts HDI by degree of inequality | UNDP — Human development angle |

| Middle 40% | 30% | ~30% |
| Bottom 50% | 13% | ~5% |
Oxfam's 2025 report found that total billionaire wealth increased by USD 2 trillion in 2024 globally, with 204 new billionaires created. In India, the bottom 50% pay 64% of total GST collected, while the top 10% contribute only 4% — highlighting India's regressive indirect tax structure. CEO pay jumped 50% in 2019–2024, while worker wages grew less than 1%.
Global Inequality Report 2025 (Nobel Laureate Joseph Stiglitz)
- Since 1990, 56% of countries saw a rise in capital income share while global labour share declined
- India's labour income share declined from 32% (1990s) to ~22% (2024) — ILO data
- Top 1% owns ~41% of global wealth (Oxfam 2025)
- Rural incomes in India are ~40% lower than urban incomes
India vs. Select Countries — Gini Comparison
Causes of Poverty & Inequality in India
Structural / Historical Causes
- Colonial Drain: Dadabhai Naoroji's "Drain of Wealth" — British extracted resources creating structural poverty. Land revenue systems (Zamindari, Ryotwari) created landless laborers.
- Caste System: Varna-based occupational segregation limited mobility. Dalits/Adivasis historically denied land, education, and economic opportunities. Horizontal inequality embedded in culture.
- Land Inequality: Incomplete land reforms post-independence. Agricultural laborers remain landless. Top 10% of rural households own 60%+ of agricultural land.
- Green Revolution Bias: Benefited Punjab/Haryana and large farmers disproportionately. Created regional and within-agriculture inequality.
Economic Causes
- Unemployment & Underemployment: India's LFPR is low (~55%). Large informal sector (90%+ of workforce) with no job security, minimum wage violations.
- Capital-Labour Imbalance: Post-liberalisation growth was capital-intensive, not labour-intensive. Benefits accrued more to capital owners (top percentile).
- Agricultural Distress: 45% of workforce in agriculture contributes only ~18% of GDP. Farm incomes stagnant. Indebtedness. Price volatility.
- Credit Exclusion: Poor lack collateral → excluded from formal credit → forced into high-interest informal lending → poverty trap.
- K-shaped Recovery (Post-COVID): Wealthy recovered faster or gained (stock markets, real estate). Poor suffered job losses in informal economy. This accelerated inequality.
Social / Human Capital Causes
- Education Inequality: Quality gap between private and government schools. Rural areas lack teachers, infrastructure. First-generation learners face structural disadvantage.
- Health Inequality: India spends only ~2.1% of GDP on public health (target 2.5%). Out-of-pocket health expenditure is ~47% of total health spending — catastrophic for poor households.
- Gender Discrimination: Women's unpaid care work not counted in GDP. Female LFPR is ~27% (one of the lowest globally). Gender wage gap persists.
- Malnutrition-Poverty Cycle: Malnourished children → poor cognitive development → poor education outcomes → low earnings → next generation born poor.
Policy/Governance Causes
- Regressive Taxation: Heavy reliance on indirect taxes (GST) which burden the poor proportionally more. Low direct tax base (only ~8 crore income tax filers in a 140-crore nation).
- Under-investment in Public Goods: Inadequate schools, hospitals, infrastructure in poor areas. Benefits of government spending skewed toward urban/rich.
- Leakages in Welfare: Before DBT, leakages in PDS were ~40-65%. Corruption in MGNREGA wage payments.
- Elite Policy Capture: Powerful interest groups shape policy to benefit themselves (corporate tax cuts, agricultural subsidy patterns benefiting large farmers).
