I do have an observation on birth order in twins: in Italy, I was told in the 1970's by an Italian physician who is an identical twin, the assumed relative age of twins is the opposite of what we assume. We say the one born first is older, whereas in Italy, he told me, the second born is legally considered the elder, on the pre-scientific "first in, last out" principle! As if that fertilized egg had been shoved to the far end of the womb by the second one. Can any of you folks verify this? Googling is no help on this vital issue of cross-cultural understanding.
That pre-scientific idea is fairly widespread among common people, but it does not have a legal value I think. Anyhow, believe it or not, I cannot find a definitive answer to your question even googling in Italian!
The most serious reference I can find is this FAQ in the website of an important governative Health Institution:
www.iss.it/gemelli/index.php?lang=1&id=1329&tipo=61
I translate for you the first paragraph:
There is no "bigger" or "older" in a twin pair. From the point of view of birth-registration, in Italy, in the Certificates of Attendance at birth (CedAP) in case of a twin childbirth the order of birth counts. So there is a first-born, a second-born, etc...
(In the other paragraphs of the text it is explained that scientifically one cannot say who was conceived first.)
So no, the second-born is not considered (legally) the elder in Italy. But I am not even sure that the converse is true. Because I think that this CedAP (a certificate where various information concerning the birth are noted, like malformations and stuff) must be kind of a new thing, and I am not sure about how much of a legal validity it has. At this point I suspect that it is up to the parents to choose the legal order when they go to the city hall to declare the newborns.
