India will be the third largest economy in the world after China and United States by 2050. A US-based internationally recognised foreign-policy think tank has said that China, India, and the United States will emerge as the world’s three largest economies in 2050 and their total GDP, in real US dollar terms, will be over 70 per cent more than that of the other G-20 countries combined. The Carnegie Endowment for International Peace said China will become the world’s largest economy in 2032, and will grow 20 per cent larger than the United States by 2050. Over the next forty years, nearly 60 per cent of G20 economic growth will come from Brazil, China, India, Russia, and Mexico alone.<br/>India's annual average GDP growth between 2009-2050 is predicted to 6.19 per cent. But these emerging markets will not rise among the world’s richest countries in per capita terms. Their average income in 2050 will still be 40 per cent below that of the G7 nations presently. <br/> <br/>
