Poverty, development & the social sector
Poverty measurement, development models and India's social sector architecture—from Tendulkar/Rangarajan lines to MGNREGA, NFSA and multidimensional poverty—for UPSC GS-1.
From the calorie norm to multidimensional poverty
Poverty measurement in India has been a contested statistical and political enterprise since independence. The original yardstick, fixed by the Planning Commission's 1979 Task Force (Y.K. Alagh), was a calorie norm—2,400 kcal per person per day in rural areas and 2,100 kcal in urban areas—translated into a monetary poverty line. The Lakdawala Committee (1993) retained the calorie anchor but updated price indices, generating separate state-level lines.
The Tendulkar Committee (2009) broke from pure calorie counting, adopting a Mixed Reference Period and a basket including health and education. It pegged poverty at roughly Rs. 27 (rural) and Rs. 33 (urban) per capita per day for 2011-12, estimating 21.9% of Indians below the line—a figure ridiculed in Parliament as too austere. The Rangarajan Committee (2014) raised the thresholds to Rs. 32 (rural) and Rs. 47 (urban), lifting the headcount to 29.5% for 2011-12. No official income-poverty estimate has been published since, because the 2017-18 NSSO Consumption Expenditure Survey was junked over data-quality concerns; the 2022-23 Household Consumption Expenditure Survey has since revived the series.
The multidimensional turn
Global practice shifted from income to capabilities, drawing on Amartya Sen's framework. NITI Aayog's National Multidimensional Poverty Index (MPI), built on the OPHI–UNDP Alkire-Foster method, uses 12 indicators across three dimensions—health, education and standard of living. The 2023 report (using NFHS-5, 2019-21) found 14.96% of Indians multidimensionally poor, down from 24.85% in 2015-16, implying about 135 million people exited multidimensional poverty in five years. Bihar, Jharkhand and Uttar Pradesh remained the poorest states.
Why measurement is politics
The poverty line is not academic: it determines entitlement. Below-Poverty-Line (BPL) status historically gated subsidised PDS grain, Antyodaya cards and welfare access, so a lower line shrinks the welfare net. The Saxena Committee (2009) and the Hashim Committee (2012) on urban poverty recommended exclusion/inclusion criteria for BPL identification, eventually feeding the Socio-Economic and Caste Census (SECC) 2011, which replaced the BPL survey with automatic inclusion/exclusion parameters. SECC data now drives PM-Awas, Ujjwala and Ayushman Bharat targeting.
Key high-yield facts to retain: the calorie norms (2,400/2,100 kcal); the committee sequence Alagh→Lakdawala→Tendulkar→Rangarajan; the MPI's 12 indicators and the 14.96% (2023) figure; and that SECC 2011, not a poverty line, now identifies beneficiaries. Candidates should be able to argue why consumption-based and capability-based measures yield divergent conclusions, and why the absence of an official income-poverty estimate after 2011-12 is itself an exam-worthy governance gap.
