Video — World Demographics

The following video chat from The Economist tackles a topic that’s been of great concern to the American public for some time: global population growth. In just a little over one minute, it shows that overpopulation isn’t as big an issue as popularly believed.

So overall, the world population is stabilizing, with many countries — including many in the developing world — experiencing negligible or even negative population growth. Most of the population increase stems from longer lifespans and the “demographic momentum” of younger generations coming into child-rearing age (at which point they will have increasingly fewer children, if any at all).

The following map confirms that most of the biggest population gains will be concentrated almost entirely in Sub-Saharan Africa:

Of course, this doesn’t mean population growth won’t bring its problems, given that most of the growth is concentrated in nations that lack the resources, infrastructure, and institutions to optimally accommodate their ever-larger number of citizens.

However, as much of the rest of the world experiences a stagnating or declining labor force — not to mention the subsequent financial and economic burdens — nations with more youthful populations may gain a considerable advantage on the global market for human resources.

If poorer nations manage to tap into the potential talent of their young and vibrant people, investing in education and infrastructure to facilitate and promote opportunities, they may well reach unprecedented levels of prosperity and influence — provided they are not turned into giant factories for foreign companies first.
