Pondering Population Trends

My colleague helpfully pointed out to me Jack Goldstone's essay in the current issue of Foreign Policy which highlights four megatrends, the response to which will significantly define how life is experienced in the decades to come.

But twenty-first-century international security will depend less on how many people inhabit the world than on how the global population is composed and distributed: where populations are declining and where they are growing, which countries are relatively older and which are more youthful, and how demographics will influence population movements across regions.

A worthwhile read.
