The Economy of India is the tenth largest in the world by nominal GDP and the fourth largest by purchasing power parity (PPP). The country's per capita GDP (PPP) per capita is $3,339 (IMF, 129th) in 2010. Following strong economic reforms from the post-independence socialist economy, the country's economic growth progressed at a rapid pace, as free market principles were initiated in 1991 for international competition and foreign investment. Despite fast economic growth India continues to face massive income inequalities, high unemployment and widespread malnourished children.
