India determines its household poverty line by summing up the individual per capita poverty lines of the household members. This practice is similar to many developing countries, but different from developed countries such as the United States who adjusts their poverty line on an incremental basis per additional household member. For example, in the United States, the poverty line for a household with just one member was set at $11,670 per year for 2014, while it was set at $23,850 per year for a 4-member household (or $5963 per person for the larger household). The rationale for the differences arise from the economic realities of each country. In India, households may include surviving grandparents, parents, and children. They typically do not incur any or significant rent expenses every month particularly in rural India, unlike housing in mostly urban developed economies. The cost of food and other essentials are shared within the household by its members in both cases. However, a larger portion of a monthly expenditure goes to food in poor households in developing countries, while housing, conveyance, and other essentials cost significantly more in developed economies.
