I am not advocating any solution to this, least of all any form of coercion. But the math is what the math is. Make of it what you will, but handwaving won't get rid of the fire-breathing Smaug in the room:

If this assessment is wrong then how else are so many more women having kids? Aliens? Magic? Help me out here, where's the error?
