Q.Explain, in general terms, the method used to construct an absolute poverty line.

Estimating an absolute poverty line is a deliberate, step-by-step method rather than an arbitrary number, starting from a nutritional benchmark. …

The general method used to construct an absolute poverty line proceeds in a series of steps. First, nutrition experts specify a minimum calorie-intake requirement per person per day needed for basic subsistence — historically, separate norms have been used for rural and urban areas, reflecting assumed differences in physical activity levels. Second, this calorie norm is converted into a corresponding basic basket of food items (and, in more modern methodologies, non-food essentials such as clothing, fuel, and a minimal allowance for health and education) that would deliver that calorie intake. Third, the current market value/cost of this basic basket is calculated, and this cost becomes the poverty-line expenditure figure, typically expressed as a minimum required monthly per-capita consumption expenditure.

Any household whose actual per-capita consumption expenditure falls below this poverty-line figure is classified as living below the poverty line (BPL), while those at or above it are classified as non-poor. As a purely illustrative example (using a clearly hypothetical, not a real, figure): if the basic basket is estimated to cost a hypothetical ₹P per person per month, a household of size $n$ with total monthly expenditure $E$ is classified as poor if $\frac{E}{n} < P$ — poverty status depends on expenditure per person, not on total household expenditure alone. …

An alternative way to state the same method: Step 1 — fix minimum calorie norm → Step 2 — identify a basket of goods meeting that norm → Step 3 — price the basket → Step 4 — the pri …

A frequent mistake is quoting a specific current rupee poverty-line figure or a specific national poverty percentage as if it were a permanent fact — these figures are periodically revised and should not …
