Why this matters now
Poverty estimation decides who is counted as poor and who gets entitlements — so methodology is politically and analytically charged. With no official income-based poverty headcount published since 2011-12 for years, the NITI Aayog National Multidimensional Poverty Index and the renewed Household Consumption Expenditure Survey (2022-23, 2023-24) have reframed the debate.
The basic idea
A poverty line is a threshold of consumption below which a person is deemed poor. India traditionally measures it through Monthly Per-Capita Consumption Expenditure (MPCE) drawn from the NSSO Consumption Expenditure Survey. The original (1979) approach fixed the line at the expenditure needed to buy a basket meeting a calorie norm — 2,400 kcal/day in rural areas and 2,100 kcal/day in urban areas.
The expert committees
| Committee | Year | Key idea |
|---|---|---|
| Lakdawala | 1993 | State-specific poverty lines; CPI-based updating; retained the calorie anchor. |
| Tendulkar | 2009 | Moved from calorie anchor to a broader consumption basket (incl. health and education spending); used a common all-India basket; set the widely-cited “₹27/₹33 a day” lines that drew criticism. |
| Rangarajan | 2014 | Raised the lines (≈₹32 rural / ₹47 urban per day, 2011-12 prices); separate rural/urban baskets; included normative food + essential non-food. Its estimates were not formally adopted as official. |
The multidimensional turn (MPI)
Income lines miss deprivation in health, education and living standards. The global MPI (UNDP & OPHI) and the NITI Aayog National MPI use indicators across three dimensions — health (nutrition, child mortality, maternal health), education (years of schooling, attendance) and standard of living (cooking fuel, sanitation, drinking water, electricity, housing, assets, bank account). NITI Aayog has reported a sharp fall in multidimensional poverty between NFHS-4 (2015-16) and NFHS-5 (2019-21), and estimates that a large number of people have exited multidimensional poverty in recent years.
The continuing debate
Key tensions: whether a single national line can capture regional cost differences; whether the Tendulkar line was set too low; how to reconcile income-based and multidimensional measures; and the long gap in official consumption data (now addressed by the HCES 2022-23 and 2023-24). For Mains, argue for a transparent, regularly-updated, multi-pronged measurement that combines consumption and multidimensional indicators.
UPSC angle
Sequence the committees (Lakdawala → Tendulkar → Rangarajan) and contrast calorie-anchored vs basket-based lines. For Mains, link the income line to the multidimensional MPI and the policy implication of how poverty is defined.
Frequently asked questions
How is the poverty line estimated in India?
Traditionally through Monthly Per-Capita Consumption Expenditure (MPCE) from NSSO surveys, originally anchored to a calorie norm (2,400 kcal rural, 2,100 kcal urban) and later to a broader consumption basket. Increasingly, the multidimensional poverty index is used alongside.
What did the Tendulkar Committee (2009) recommend?
It moved away from the pure calorie anchor to a broader consumption basket including health and education spending, used a uniform all-India basket, and set the much-debated daily poverty lines.
What is the Multidimensional Poverty Index (MPI)?
A measure of poverty across three dimensions — health, education and standard of living — using indicators like nutrition, schooling, sanitation and cooking fuel, rather than income alone. NITI Aayog publishes a National MPI for India.
Which committee’s poverty line is official?
The Tendulkar methodology was the last to be officially used for headcount estimates (for 2011-12). The Rangarajan estimates were not formally adopted.
