Now I will speak as someone who holds a PhD in mathematics.
No, I don't think that he is joking but that he is simply confused because he lacks the technicalities who needs in order to study the problem of demographics.
He doesn't have an opinion and lends an opinion depending on what he wants to say to build his case.
For starters, someone who specializes in a country's demographics should gather and access the next, easy to find data, apart from simple fertility and death rates:
-age of first child
-number of marriages
-number of divorces
-fertility rates related with rural or city population
-fertility rates by geographical region
-death rates by accidents/bad habits
-relation of fertility/death rates with the average income
-fertility rates per religion
-fertility rates related with parents education
-sexual transmitted deceases trends
Study the trends and address the resultant outcome AT LEAST qualitatively if not quantitatively as well.
Obviously he is blissfully unaware of all this...
PS BTW from all this variables I mentioned above, all but the increase of the city population compare to the rural, run in favor of Russia's demographics!
