The Poverty Line — Concept and Measurement in India

2. The Poverty Line — Concept and Measurement in India

The poverty line is the specific income or expenditure threshold used to separate the "poor"

from the "non-poor" for official measurement purposes. A household whose income or consumption

expenditure falls below this line is officially classified as poor; a household at or above it

is not. India's approach to defining and measuring this line has evolved through several distinct

stages, each associated with a specific expert committee — this evolution is itself an important

part of what the MSBSHSE Std XI Economics syllabus expects a student to know.

1. The original calorie-based approach. India's early official poverty line, developed from the work of a Planning Commission task force in the late 1970s, defined the poverty line purely in terms of a minimum daily calorie intake per person — historically set higher for rural areas than for urban areas, reflecting the more physically demanding nature of rural occupations. A household whose expenditure was insufficient to buy this minimum calorie requirement, given prevailing local prices, was classified as poor. This is the classic "calorie-based" or "nutritional" approach to defining the poverty line: poverty is fundamentally about not being able to afford enough food energy to sustain a working life.
2. The Tendulkar Committee approach. Economists later criticised the pure calorie-based approach for ignoring genuinely essential NON-FOOD needs — healthcare, education, clothing, conveyance — that a household cannot simply do without even if it manages to meet its calorie requirement. The Tendulkar Committee, appointed by the Planning Commission, recommended moving to a broader Monthly Per Capita Expenditure (MPCE)-based poverty line that combined a food component with an explicit allowance for non-food essentials such as health and education, and also moved to a uniform basket of goods valued at prevailing market prices across states (rather than state-specific calorie norms alone). This shifted the poverty line from a narrowly nutritional benchmark to a broader "minimum acceptable standard of living" benchmark.
3. The Rangarajan Committee approach. A further expert group, the Rangarajan Committee, was subsequently asked to review the Tendulkar methodology, and proposed its own revised estimate of minimum required expenditure, again built around a food-plus-non-food consumption basket, while adjusting some of the specific items and price assumptions used. The consistent thread across all three approaches (Alagh Committee → Tendulkar Committee → Rangarajan Committee) is the same: India has steadily moved from a purely nutritional definition of poverty toward a broader consumption-based definition that better reflects what a household genuinely needs to live above bare subsistence.
4. Multidimensional Poverty. More recently, poverty measurement in India has also moved beyond income/consumption alone toward a Multidimensional Poverty Index (MPI) approach, which measures deprivation directly across several dimensions at once — health (nutrition, child mortality), education (years of schooling, school attendance), and standard of living (cooking fuel, sanitation, drinking water, electricity, housing, assets). A household can be counted as multidimensionally poor if it is significantly deprived across enough of these indicators together, even if its cash income alone might not place it below a purely monetary poverty line. This approach is used by NITI Aayog as a complement to, not a replacement for, the traditional consumption-expenditure poverty line, because it captures deprivations (like poor sanitation or lack of schooling) that a single income number can miss entirely. …
