Divergent long-term growth patterns lead to radical shifts in the relative size of economies. The United States is expected to cede its place as the world's largest economy to China, as early as 2016. India’s GDP is also expected to pass that of the United States over the long term. Combined, the two Asian giants will soon surpass the collective economy of the G7 nations. Fast-ageing economic heavyweights, such as Japan and the euro area, will gradually lose ground on the global GDP table to countries with a younger population, like Indonesia and Brazil (see chart).
