India's poverty line: from Naoroji to Rangarajan

Detail

Core concepts

• Poverty line: the minimum income or consumption spending a person needs to meet basic needs such as food, clothing and shelter.
• People who spend less than this are counted as poor, or BPL (Below Poverty Line).

• In India, expert groups set the line. No law fixes it.

• Head Count Ratio (HCR): the share of the population that lives below the poverty line.

• Formula: HCR = (Number of people below the poverty line ÷ Total population) × 100

• Worked example: a district has 50 lakh people, and 11 lakh of them spend less than the line. HCR = (11 ÷ 50) × 100 = 22%.

• MPCE (Monthly Per Capita Consumption Expenditure): a household's monthly spending divided by the number of people in it. India draws its poverty lines in MPCE terms, not income terms.

• Absolute vs relative poverty:
• Absolute poverty: below a fixed minimum standard. This is India's method.
• Relative poverty: poor compared with others in the same society, for example below half of the median income.

Early estimates (before Independence to 1971)

• Dadabhai Naoroji, Poverty and Un-British Rule in India (1901).
• He worked out the cost of a basic "jail diet" (the food given to prisoners): about ₹16–35 per head per year at 1867-68 prices.
• Per capita income was only about ₹20 a year.

• Result: most Indians could not afford even what prisoners ate. He used this to argue that colonial rule was making India poor. For the colonial drain of wealth, see colonial-economy-1947.

• National Planning Committee (1938), set up by the Congress under Nehru, raised the idea of a national minimum standard of living.

• Bombay Plan (1944), written by leading industrialists, put the minimum at about ₹75 per head per year.
• Planning Commission Working Group (1962): ₹20 rural and ₹25 urban per capita per month at 1960-61 prices. This was the first official line after Independence.
• Dandekar-Rath (1971):
• It used a norm of 2,250 kcal per person per day.
• This gave ₹15 rural and ₹22.5 urban per month at 1960-61 prices.
• It was the first systematic estimate built on NSS (National Sample Survey) data.

The calorie-norm era (1979–2009)

• Alagh Task Force (1979) created the calorie-based poverty line: the monthly spending at which a person can buy enough food for a minimum daily calorie intake.
• Norms: 2,400 kcal rural and 2,100 kcal urban per person per day. The rural norm is higher because rural work involves more heavy manual labour.
• Lines: ₹49.09 rural and ₹56.64 urban per capita per month at 1973-74 prices (NSS 28th round).

• Weakness: later lines were only updated for prices. The basket of goods stayed frozen at 1973-74, even as people's consumption changed.

• How a price update works (worked example):

• New line = Old line × (Price index in new year ÷ Price index in base year)
• Suppose the rural line is ₹49.09 and the price index rises from 100 to 250. Then the new line = 49.09 × 2.5 = ₹122.7.

• The line keeps up with inflation, but it still buys the same old basket.

• Lakdawala Expert Group (1993):

• Kept the Alagh basket but made the lines state-specific, so each state got its own rural and urban line.
• Updated rural lines with CPI-AL (Consumer Price Index for Agricultural Labourers) and urban lines with CPI-IW (Consumer Price Index for Industrial Workers).

• Did not scale NSS consumption up to national-accounts consumption, which earlier practice had done. Survey data were used as they were.

• Critique: the "calorie puzzle" (Deaton-Drèze).

• What happened: real spending per head (spending after removing the effect of inflation) went up, but average calorie intake went down.
• Likely reasons: less heavy manual work, better health (less energy lost to illness) and a more varied diet (more milk, fruit and protein, fewer cheap cereals).
• Result: people eating fewer calories are not always poorer, so a line tied to calories measures poverty wrongly.

Tendulkar Expert Group (2009)

• Dropped the calorie anchor.
• It used one all-India urban basket (a PLB, or poverty line basket).

• The basket was anchored to Lakdawala's 2004-05 urban poverty rate of 25.7%.

• MRP (Mixed Recall Period): a way of asking households how much they spent.

• 365-day recall for things bought rarely: clothing, footwear, durable goods, education and hospital care.
• 30-day recall for everything else.

• A longer recall for rare purchases gives a truer picture than asking only about "last month".

• Explicitly counted spending on health and education.

• Took price differences between states, and between rural and urban areas, from NSS unit values (the price per unit that households reported paying).
• 2011-12 lines: ₹816 rural and ₹1,000 urban per person per month [4].
• Per day: 816 ÷ 30 ≈ ₹27 rural; 1,000 ÷ 30 ≈ ₹33 urban.

Year	HCR (Tendulkar)
2004-05	37.2%
2009-10	29.8%
2011-12	21.9% (rural 25.7, urban 13.7; about 27 crore poor) [4]

• Pace of decline:
• Poverty fell by 2.18 percentage points per year between 2004-05 and 2011-12 [4].

• That was about three times the rate of the 11 years from 1993-94 to 2004-05 [4].

• The "₹32 a day" row (2011).

• The Planning Commission's affidavit in the Supreme Court implied an urban line of about ₹32 a day.
• Many people felt this figure was far too low to live on. The public backlash led to the Rangarajan group.

Rangarajan Expert Group (2014)

• Went back to a normative food basket (a basket based on what people should eat, not only on what they do eat):
• 2,155 kcal rural and 2,090 kcal urban.

• Plus protein and fat norms. This was the first time these were added.

• Non-food part: essential non-food spending on clothing, housing (rent), education and conveyance (transport), as seen in the median fractile.

• Median fractile: the middle group of households when all households are ranked by spending.

• Used MMRP (Modified Mixed Recall Period) data [2]. MMRP is a refined MRP that uses a shorter recall for items bought often, such as some food items, so that spending is not under-reported.

• Lines (2011-12): ₹972 rural and ₹1,407 urban per person per month [2].
• Per day: about ₹32 rural and ₹47 urban.

• For a family of five: ₹4,860 rural and ₹7,035 urban per month [2].

• Compared with Tendulkar: the Rangarajan lines are 19% higher (rural) and 41% higher (urban) [2].

• Part of this rise came from switching to MMRP data. MMRP explains about 67% of the rural increase and 28% of the urban increase [2].

• HCR 2011-12: 29.5% (rural 30.9, urban 26.4). That is 36.3 crore poor.

• Status: it was never formally adopted.
• NITI Aayog Task Force on Elimination of Poverty (chaired by Arvind Panagariya, 2016) did not recommend a line [3].
• Result: India has had no official poverty line or poverty estimate since 2011-12.

Beyond the income line: multidimensional poverty

• Multidimensional Poverty Index (MPI): counts people as poor if they lack several basic things at once, such as nutrition, schooling, cooking fuel, sanitation or housing, instead of looking only at spending.

• India's National MPI is published by NITI Aayog. It covers health, education and standard of living [6].

• Latest estimate: multidimensional poverty fell from 29.17% (2013-14) to 11.28% (2022-23), a drop of 17.89 percentage points [5].

• About 24.82 crore people escaped multidimensional poverty over those nine years [5].
• Largest falls: Uttar Pradesh (5.94 crore), Bihar (3.77 crore), Madhya Pradesh (2.30 crore) and Rajasthan (1.87 crore) [5].

• The government credits schemes such as Swachh Bharat Mission, PM Ujjwala Yojana and Jal Jeevan Mission [5].

• Caution: the MPI is not a poverty line. It measures deprivation, not whether spending is below a money threshold.

International line (World Bank)

• International Poverty Line (June 2025 update): raised to $3.00 a day (2021 PPP) from $2.15 [7].
• PPP (Purchasing Power Parity): an exchange rate that equalises what money can buy in different countries.

• $3.00 is the median of 23 national poverty lines of low-income countries (Burkina Faso's $3.04, rounded down) [7].

• India, 2022-23 (based on HCES 2022-23):

• 5.25% extreme poverty at the $3.00 line [8].
• 2.35% at the older $2.15 line [8].

• HCES (Household Consumption Expenditure Survey) 2022-23 collected data only on MMRP [8].

• Global effect: the new line alone would have added 226 million people to global extreme poverty. India's revised data cut 125 million, so the net global rise was 125 million [8].

NCERT error

• Where: Class 11, Comparative Development Experiences of India and its Neighbours, Table 8.5. It lists India's national BPL share as 21.9% for "2019-21", and also shows 21.9% for Pakistan.
• The fact: 21.9% is the Tendulkar estimate for 2011-12 [4]. Do not quote it as a recent figure.

Prelims Hooks

• Dadabhai Naoroji estimated a subsistence "jail diet" at ₹16–35 per head per year (1867-68 prices), in Poverty and Un-British Rule in India (1901).
• Dandekar-Rath (1971): the first systematic poverty estimate using NSS data, based on a norm of 2,250 kcal.
• Alagh Task Force (1979): 2,400 kcal rural / 2,100 kcal urban. Lines were ₹49.09 / ₹56.64 at 1973-74 prices.
• Lakdawala (1993): made lines state-specific and updated them with CPI-AL (rural) and CPI-IW (urban).
• Tendulkar (2009): dropped the calorie anchor and used MRP. 2011-12 lines were ₹816 / ₹1,000, and HCR was 21.9% [4].
• Rangarajan (2014): 2,155 / 2,090 kcal plus protein and fat norms, using MMRP. Lines were ₹972 / ₹1,407, and HCR was 29.5% (36.3 crore). It was never adopted [2].
• Trap: India's last official poverty estimate is for 2011-12. The 2016 NITI Task Force (Panagariya) set no new line [3].
• Trap: the National MPI (NITI Aayog) figure of 11.28% (2022-23) is not a poverty-line HCR [5].
• World Bank International Poverty Line: $3.00/day (2021 PPP) from June 2025. India's rate was 5.25% (2022-23) [7][8].
• Calorie puzzle (Deaton-Drèze): real spending went up while calorie intake went down.

Mains Points

• Calorie line vs a broader basket: the calorie puzzle shows that calories alone mismeasure poverty.
• Tendulkar's approach covered health and education spending.
• Rangarajan went back to food norms but added protein and fat.

• Any new line must balance nutrition, non-food essentials and price differences between regions.

• A 14-year data gap (since 2011-12): without an official line, targeting depends on proxies.

• The Socio-Economic Caste Census (SECC) is used for NFSA and PMAY coverage.

• HCES 2022-23 now gives a base for fixing a new line, which would make targeting more accurate and support SDG 1 tracking [8].

• Money-based vs multidimensional measures: the MPI shows gains from better access to basic services, such as the fall from 29.17% to 11.28% [5]. It does not show whether spending is enough, or how exposed people are to price shocks, so both measures are needed.

• Method changes the headcount: the switch from MRP to MMRP alone raises the line and changes the poverty rate [2][8].
• This is why poverty numbers from different methods must not be compared directly.
• It is also why the choice of method is a political question as well as a technical one.
