Is the human population decline in the near future ?

Check out the documentary Demographic Winter. It features the Nobel Prize-winning Chicago economist Gary Becker, inter alii. It shows how economists are predicting a peak in world population by circa 2050.

I am wondering what Austrian economists would think of this. Do they see a negative effect on an economy due to birth-rate limiting behaviours like contraception, abortion, sodomy, cohabitation, divorce, etc., all of which were illegal in the United States until recently? This would seem to be right up Mises’s “human action” alley. Perhaps he discusses, without necessarily passing a moral judgment, the effects of these human actions on an economy in his Human Action? Thanks

If you think this will hijack this thread, I’ve started a new one here.
