Birthright citizenship is by no means the standard. It’s not rare, but most of the world does not use it. Most of them are in the Americas, but that whole thing gets complicated.
Most countries grant citizenship to the children of their citizens. IOW, the child inherits citizenship from its parents. If nothing else, the mother is going to be known by nature of the birth, and the child would have at least her citizenship.
(Exceptions exist, but they exist for Jus Soli as well)












I assume that’s the “weight” of the paper, I.e. how thick the pages are.
