Poverty is defined as a lack of basic human needs like food, shelter, and clothing. It can be measured through relative poverty, which is a lack of resources relative to a society, and absolute poverty, which is a lack of resources to satisfy basic physical needs. India's poverty rate has declined from 45% in the 1990s to 22% in 2011-2012 according to government estimates, though poverty remains a significant problem, especially in rural areas and certain states. Poverty is caused by issues like overpopulation, unemployment, underdevelopment, and low economic growth. The government has implemented various programs aimed at poverty alleviation and increasing employment opportunities in rural areas.
