Every time people are prevented from doing what they normally do and have to find their own entertainment at home (blackouts being a prime example of this), 9 months later we inevitably have a bump in births because… well.. people.
So, I am calling it now, we will definitely see not only a bump but a veritable “hump” in the birth rate come November/December 2020.
The only real question, given the unprecedented and global nature of the the stay-at-home quarantines, is HOW big.
With absolutely zero scientific data behind it, I am going to go out on a limb and predict that, not only will the increase in birth rate overcome the tragic increase in the base death rate due to Covid-19, but I suspect that people will be eager enough to end up with a net increase in the world population by the end of 2020 over and above what we naturally would see with normal population growth.
Whether this is a good thing remains to be seen, but I expect that it will be a hopeful thing for those involved…
