According to Central Statistical Organization (CSO), the per capita income of India has increased to Rs. 33,283 in 2007-08; a healthy growth of 12.7%. The per capita income has been growing above 10% since 2003-04, rising almost 60%.
This is the result of the impressive economic growth rate recorded by India during this time period and is supposedly the indication of an overall improvement in the living standards of people.
I’m not sure how representative a figure this is, in a country that has 4 out of the top 10 richest people in the world, a fair amount of income inequality and a third of the population still living below the poverty line.
