“Barth finds in his study of southern Kurdistan that in tribal villages 57% of all marriages were cousin marriages (48% bint ‘amm marriages) while in a nontribal village made up of recent immigrant families only 17% were cousin marriages (13% bint ‘amm).”
the barth reference is: Barth F. (1954) Father’s brother’s daughter marriage in Kurdistan. South Western Journal of Anthropology 10, 164-171.
what piques my interest here is the difference in cousin marriage rates between the traditional kurdish tribal villages (57%) and nontribal villages “made up of recent immigrant families“ (17%).
while it seems like it should be obvious that immigration would reduce cousin marriage rates, this is the first actual example i’ve (almost) seen of that. in other cases of immigration that i’ve seen — europe in general in the late-1800s (see second half of this post), germans in gdańsk in the 1500-1700s (see here), and, for example, not to be forgotten, pakistanis and their chain-migration patterns in places like the u.k. today — the cousin marriage rates have actually gone UP in connection with immigration. here — finally, then — is an example of cousin marriage decreasing with immigration — by a LOT, apparently.
so it seems like the effect of emigration on cousin marriage rates is something that can vary depending on circumstances, although what those circumstances are, is not clear to me.

a little bit on iceland (and the faroe islands) from The Faroe Islands: Interpretations of History [pg. 14]:
“The Church’s power [in the faroe islands] was also moral, and the workings of ecclesiastical law may have contributed to the relative impoverishment of freeholders. We do not know what ecclesiastical law was in the Faroes before the Reformation; only that in 1584 the Løgting complied with Frederick II’s request that a compilation of late thirteenth-century Icelandic law called the Stóridómur continue to be valid in the Faroes. Among other things, the Stóridómur set the bounds within which kinsmen were forbidden to marry; since marriage between cousins was held to be incestuous, lands divided by inheritance could not easily be recombined. After the Reformation, the Stóridómur was supplemented by secular laws prescribing harsh punishments for bearing or fathering children out of wedlock (death, if the parents were cousins) and allowing couples to marry only if they had a certain amount of land. Similar restrictions on marriage were in effect earlier as well. It could hardly be otherwise in so ecologically precarious a land, where overpopulation was always a threat. Thus the Seyðabræv had ‘established certain requirements for a man if he was to be able to marry and set up his own house’: none could do so without being able to support at least three cows. In effect, the poor were forbidden to marry.”
so it sounds as though by at least the 1580s — and very likely the late 1200s — cousin marriage was banned in iceland in this stóridómur (and, then, from at least the 1580s onwards on the faroe islands). that cousin marriage was banned in iceland starting in the late 1200s — if that’s what happened (i’m still not sure yet) — would fit my prediction that cousin marriage was probably banned there when the norwegian crown took over iceland in 1262. my bet is that the ban was introduced to the island at that point in time from the continent.
i haven’t found out much about this stóridómur — here is the icelandic wikipedia page google translated. sounds like it wasn’t compiled until the 1560s, but, perhaps, based upon earlier law tracts? dunno. it does mean something like “big judgement” or something like that.
and how about the faroe islands there?! those were some eugenical practices (if they enforced them, which it actually sounds like they did, if you read through the book above)! the faroese ought to be geniuses! (~_^)
conclusion: we need more physicists studying/being interested in human biodiversity/sociobiology/anthropolgy!:
(probable) reason: they’re more logical/have higher iqs.
“Iannone: How did your interest in anthropology begin? What made you want to be an anthropologist?
“Chagnon: My original major as an undergraduate in a local two-year college — Michigan College of Mining and Technology — was physics. At that time I had never heard of anthropology. I transferred to the University of Michigan after my first year and discovered that ‘physics’ was in the College of Literature, Science and the Arts and I would have to take courses in each of these fields. The only thing I could fit into my schedule for the social science requirement was a course in a field called anthropology.”
