2-Minute Revision

Poverty line estimation in India has evolved from a simple calorie-based approach to more comprehensive consumption expenditure models. The Alagh Committee (1979) set the initial calorie norms (2400 kcal rural, 2100 kcal urban).

The Lakdawala Committee (1993) introduced state-specific poverty lines using different price indices. A major shift occurred with the Tendulkar Committee (2009), which moved away from a purely calorie-based approach, adopting a unified consumption basket that included health and education expenditure, and using a Mixed Reference Period (MRP).

This resulted in a higher poverty count. The Rangarajan Committee (2014) further refined the methodology, proposing higher calorie norms, separate consumption baskets for rural and urban, and higher monetary poverty lines than Tendulkar.

While the Rangarajan recommendations are the latest, the government has not officially adopted them, often referencing Tendulkar's framework. Internationally, the World Bank uses Purchasing Power Parity (PPP) to set poverty lines, with the extreme poverty line currently at $2.

15 PPP per day. The debate continues over the most accurate and acceptable method, with increasing focus on the Multidimensional Poverty Index (MPI) for a holistic view.

Poverty line estimation is crucial for identifying the poor and targeting welfare schemes in India, rooted in the constitutional mandate of Article 47 (DPSP). The journey began with the Alagh Committee (1979) defining poverty based on calorie intake (2400 kcal rural, 2100 kcal urban).

This was refined by the Lakdawala Committee (1993), which introduced state-specific poverty lines updated using CPI-AL and CPI-IW, acknowledging regional price variations. The Tendulkar Committee (2009) marked a paradigm shift, moving away from a purely calorie-based approach.

It adopted a consumption expenditure-based methodology, incorporating a unified poverty line basket for both rural and urban areas (though monetary values differed) and explicitly including expenditure on health and education.

This led to a higher poverty ratio (21.9% for 2011-12). The Rangarajan Committee (2014) was formed to address criticisms of the Tendulkar line. It proposed higher calorie norms (2155 kcal rural, 2090 kcal urban), reverted to separate consumption baskets for rural and urban, and recommended higher monetary poverty lines (Rs.

972 rural, Rs. 1407 urban for 2011-12), resulting in a higher poverty ratio (29.5% for 2011-12) than Tendulkar's for the same year.

Despite these advancements, poverty line estimation remains contentious due to methodological arbitrariness, political sensitivity, and its unidimensional nature. It often leads to exclusion/inclusion errors in targeting poverty alleviation schemes .

The international comparison uses World Bank's PPP-based lines (e.g., $2.15 PPP for extreme poverty) to account for purchasing power differences. Currently, while Tendulkar's framework is often referenced, there's a growing emphasis on the Multidimensional Poverty Index (MPI) by NITI Aayog for a more comprehensive understanding of deprivation, reflecting a shift towards a holistic approach to poverty measurement and policy.

Understanding these nuances is key for UPSC.

Prelims Revision Notes

<h3>Poverty Line Estimation: Prelims Quick Facts</h3> <ul> <li>Alagh Committee (1979): First to define poverty line based on calorie norms. Rural: 2400 kcal/day; Urban: 2100 kcal/day.

Better regional accuracy.</li> <li>Tendulkar (2009): Paradigm shift. Moved from calorie. Unified PLB, MRP. Included health/education. Higher poverty count (e.g., 21.9% for 2011-12). More realistic non-food expenditure.

</li> </ul> Critique & Challenges: <ul> <li>Methodological Arbitrariness: Calorie norms, basket composition.</li> <li>Unidimensionality: Ignores non-income deprivations (health, education, housing, public services).

Leads to MPI .</li> <li>Exclusion/Inclusion Errors: Impacts targeting of poverty alleviation schemes and BPL surveys .</li> <li>Political Economy: Numbers influence resource allocation, public perception, political accountability.
