"Population declines following economic collapse" should be "Population declines following sustained drop in birthrate." The population is going to decline regardless of what the future economy does.
- kragen 15y agoI'm not very familiar with their model, but if the birthrate asymptotes to above the replacement rate, or goes back up, the population won't decline. So the economy might be a factor.
- schiffern 15y agoscottw is referring to the well-studied demographic transition. http://en.wikipedia.org/wiki/Demographic_transition http://en.wikipedia.org/wiki/Demographic_transition
- toomuchtodo 15y agoTL;DR The world is getting older, hence less babies born.
- toomuchtodo 15y agoDownvote? For quickly summarizing a wikipedia link? I guess we all have time to waste skimming wikipedia articles, don't we?
- schiffern 15y agoThe problem is that it's wrong. A better summary would be, "The world is getting richer, hence lower infant mortality, hence birth rates drop."
- toomuchtodo 15y agoThe world is graying extremely quickly (Japan, Western Europe, the US, and soon China).
- kragen 15y agoI knew that already.
