One fifth of the world's poor live in South Asia, with 26% of Indians living below the poverty line. Poverty is concentrated in rural areas and three states - Uttar Pradesh, Bihar, and Madhya Pradesh - account for half of India's poor. Low income and lack of healthcare contribute to high female illiteracy and infant mortality rates. While India's economy is growing, wealth is unevenly distributed and many rely on agriculture for income. Efforts to alleviate poverty include microfinance programs and government poverty elimination plans, and India's middle class is growing rapidly.
