there are many things at play as a society develops that play a part in population declines, to assume that vaccinations are part of it is absurd. it is primarily industrialisation, economics, education, emancipation of women, contraception, opportunity. to state that one of the advances (vaccination) that is an offshoot of some of those things mentioned is a causal factor of another offshoot (declining population growth) is putting the cart before the horse.
it is quite extraordinary how people correctly dismiss my little pseudoscience experiment and yet are unwilling to dismiss the same pseudoscience that bill gates is promoting. correlation does not mean causation, the reasons for declining population growth are well understood, declining population growth has about as much to do with growth in vaccinations as it has to do with growth in fridge ownership.
Seriously, you do not understand how to read scientific data or are you being deliberately obstinate?
It is a known fact that vaccines reduce infant mortality.
It is a known fact that reduced infant mortality reduces the birth rates.
I mean, how hard can it be? From Tmars78's excellent link (you should look at the scientific references in that link, by the way):
It is a well known fact that developed countries benefit from vaccines and the subsequent low infant mortality and birthrates. Even though some European countries now have declining populations was it not for immigration. What is the big mystery in this?
