The high-growth developing countries – Brazil, Russia, India, China, and others in the G-20 – now include more than half the world’s population. If they continue their current strong growth trajectories, as seems likely, they will approach advanced-country levels of income by mid-century or shortly thereafter.
快速增长的发展中国家——巴西、俄罗斯、印度、中国和其它二十国集团成员——现在已经囊括了超过世界半数的人口。如果它们目前强劲的增长势头持续下去（这种几率似乎很大），它们将在本世纪中期或稍晚一些时候在收入水平上接近发达国家。
