Below Poverty Line

Below Poverty Line is an economic benchmark and poverty threshold used by the government of India to indicate economic disadvantage and to identify individuals and households in need of government assistance and aid. It is determined using various parameters which vary from state to state and within states. The present criteria are based on a survey conducted in 2002. Going into a survey due for a decade, India's central government is undecided on criteria to identify families below poverty line.
