In most of the Americas it actually does.
- the rest of the world
- the fact that right to nationality is not the same as having it. France has the same right, but --as I already pointed out-- there are quite a few people born there who didn't take the nationality
- the fact that it can change, and that the inference becomes invalid in the future
Some would say, when describing Tim Berners-Lee, the fact he invented the web is more important than the year of his birth, his middle name, his knighthood or his nationality.
Wikipedia does get his invention of the web into the first sentence of the article [2], which is good - but not before "Sir Timothy John Berners-Lee, OM, KBE, FRS, FREng, FRSA, DFBCS, RDI (born 8 June 1955), also known as TimBL, is an English computer scientist"
Of course, it's might not be practical for Wikipedia to follow the inverted pyramid style, as it might invite edit wars about what counts as most important.

But unlike which generation you are born in, nationality is not a simple, fixed, unique thing that everyone has.
