I haven't read the article, so everything that follows is speculation. I don't believe that historical evidence supports this claim. For example, former communist countries did not have high rates of population growth. I don't know the numbers for Fascist Countries, but I don't think that the rates were too high.
I believe that more variation in population growth could be explained by looking at dominant religion than by looking at the form of government. Of course, there is some correlation between dominant religion and the form of government, which may lead to the conclusion that form of government and population growth are correlated. ----- Original Message ----- From: "Wei Dai" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, July 14, 2003 17:49 PM Subject: fertility and government > According to a recent article  in Harvard International Review, because > of differences in fertility, the population growth rate in dictatorships > is higher than that in democracies at every income level.
