The Return of Emerging Markets 

According to the Economist, the global economy is beginning to return to it's pre-industrial revolution balance, in terms of the combined output of developing vs developed country economies. In 2005, the former's share rose to over 50% of the total global output (measured in PPP though).
This figure has been calculated from the International Monetary Fund's World Economic Outlook database. We have adjusted the IMF's numbers in two ways. First, we have taken account of China's recent upward revision of its GDP by 17%. Second, we include the newly industrialised Asian economies (South Korea, Taiwan, Hong Kong and Singapore). These countries might well now be classed as developed, but should surely be counted in any estimate of the long-term success of developing countries. If you exclude countries once they prosper, developing economies' share will never increase.

We have used the IMF's method of converting national GDPs into dollars using purchasing-power parities (PPPs) instead of market exchange rates. The latter can distort the relative size of economies, not only because currencies fluctuate, but also because prices are lower in poorer economies (so a dollar of spending in China, say, is worth a lot more than it is in America).
The graph below tells its own story.
