India became 3rd-largest economy in 2011 from 10th in 2005

In a matter of six years, India emerged as the world's third-largest economy in 2011 from being the 10th largest in 2005, moving ahead of Japan, while the US remained the largest economy closely followed by China, latest figures have revealed.

"The economies of Japan and the UK became smaller relative to the US, while Germany increased slightly and France and Italy remained the same," according to data released today by the International Comparison Program (ICP), hosted by the Development Data Group at the World Bank Group.

"The relative rankings of the three Asian economies - China, India, and Indonesia - to the US doubled, while Brazil, Mexico and Russia increased by one-third or more," the report said. The world produced goods and services worth over $90 trillion in 2011 and that almost half of the total output came from low and middle-income countries, it said.

According to the major findings of the ICP, six of the world's 12 largest economies were in the middle-income category (based on the World Bank's definition).

When combined, the 12 largest economies accounted for two-thirds of the world economy and 59% of the population, it said.

The purchasing power parities (PPPs)-based world GDP amounted to $90,647 billion, compared with $70,294 billion measured by exchange rates, it said, adding that the share of middle-income economies in global GDP is 48% when using PPPs and 32% when using exchange rates.

The six largest middle-income economies - China, India, Russia, Brazil, Indonesia and Mexico - account for 32.3% of world GDP, whereas the six largest high-income economies - US, Japan, Germany, France, UK and Italy - account for 32.9%, the report said.

Asia and the Pacific, including China and India, account for 30% of world GDP, Eurostat-OECD 54%, Latin America 5.5% (excluding Mexico, which participates in the OECD and Argentina, which did not participate in the ICP 2011), Africa and Western Asia about 4.5% each.

"China and India make up two-thirds of the Asia and the Pacific economy, excluding Japan and South Korea, which are part of the OECD comparison. Russia accounts for more than 70% of the CIS, and Brazil for 56% of Latin America. South Africa, Egypt, and Nigeria account for about half of the African economy," said the report.

"At 27%, China now has the largest share of the world's expenditure for investment (gross fixed capital formation) followed by the US at 13%.

India, Japan and Indonesia follow with 7%, 4%, and 3%, respectively," the report said.
