The poverty line is an estimated, imaginary line developed by economists to define a poor person. It is calculated using certain standard measures such that all poor people lie below the poverty line and anyone above the poverty line is not poor. In India, a person is considered poor if their income or consumption level falls below a given “minimum level” necessary to fulfill basic needs. This minimum level is called the poverty line, and it is estimated by multiplying the prices of physical quantities like food, clothing, footwear, fuel, light, education, etc. in rupees. The poverty line varies with time and place, and each country uses an imaginary line that is considered appropriate for its existing level of development and its accepted minimum social norms. The poverty line is estimated periodically (normally every five years) by conducting sample surveys. These surveys are carried out by the National Sample Survey Organisation (NSSO) in India.
