Working Age Populations

I quote from The Economist:

Many emerging economies are in the sweet spot of a demographic transition, where the share of the population in their working years is rising, boosting economic growth. So far East Asia’s economies have reaped the most dramatic demographic dividend. The share of the working-age population has soared from 47% in 1975 to 64% in 2010. This surge has underpinned rapid economic growth, but is now ending. The share of the working-age population in East Asia will peak this decade and fall to 57% by 2050. In South Asia, in contrast, the share of the population of working age will continue to rise until 2040.

This suggests that India might in a few years surpass China in the rate of increase of GDP. Investors take notice.
