Demographic Change and Economic Growth in Asia

We show that the overall rate of population growth had little effect on economic growth, but that changes in life expectancy, age structure, and population density have had a significant impact on growth rates. We also find strong evidence of feedback from higher income to population change via lower fertility, though a significant component of the demographic changes appears to have been exogenous.

Our results suggest that the demographic transition can act both as a catalyst and as an accelerator mechanism, and that demographic effects can explain most of East Asia’s economic "miracle". East Asia benefited from a "virtuous spiral" of income growth and fertility decline, while South Asia seems to remain caught in a low-level population-income trap.
