One aspect this article does not address at all is the massive sex ratio imbalance in India and China (for different reasons) at around 1,100 men for every 1000 women. This means there are 100 million girls less today in these countries alone, finding a suitable partner becomes harder and there are lesser number of couples will be there in the first place who can have kids The 2.1 replacement is perhaps not adequate…
Actual numbers are way off the real numbers.
In my kids school you can see a very noticeably difference in the count of boys and girls in any standard and section. It's noticeable to a point, if you walk in to a classroom you can see at least visually boys outnumber girls by a good enough difference.
I also refuse to believe this due to infanticide or foeticide. The dirty little secret is at least in most urban centers, even tier 2 cities, these practices are dead today. You can't blame these practices for the difference anymore. How then is the difference arising?
Again on a pure anecdotal evidence basis, I see people who have boys tend to have more boys. That is male kids are born more to families with more male kids. Also having the first kid as a boy couples tend to go in for more kids. On the other hand these days if some one had a daughter as the first child they don't even bother to have another child. This way boys are born way ore than. This is a huge problem. Reason being this is not wrong by any means. This not illegal or unethical. Yet it creates a larger social problem.
These problems will never go away in India as long as there are big fat wedding expenses(Pretty much entirely paid by the girls side) and dowry. And girls not allowed to take care of their parents, both in presence help and financial help.
The other part is of course due to Thyroid illness become prevalent in India. Many couples aren't able to have kids.
I expect the gender ratio imbalance to not only continue but get way worse in India. Like really to a point, where an upper middle class man wouldn't be able to find a bride after decades of searching.
