While determining the poverty line in India, a minimum level of food requirement, clothing,footwear, fuel and light, educational and medical requirement etc. are determined for subsistence.
(i) The calorie requirement depending upon the age, sex, area and type of work is the way of estimating poverty. Average calorie requirement in India is 2400 per person per day in rural areas and 2100 per person per day in urban areas.
(ii) Monetary expenditure per capita needed is also a way of estimating poverty. In the year 2000, poverty line for a person was fixed at Rs 328 per month for the rural areas and Rs 454 for the urban areas.
(iii) A uniform standard for poverty line is also used, which is given by international organisations like World Bank. This is equivalent of $ 1 per person per day.
