consanguin-eous marriage in afghanistan

just for a change of pace.

the consanguineous (second cousin or closer) marriage rates in afghanistan are high. tells us that the rate is between 40 and 49%. more details are to be had in Consanguineous Marriages in Afghanistan (2012) and Prevalence of Consanguienous Marriages in West and South of Afghanistan (2012), including consanguinity rates by province and ethnic group.

back in the 1970s, joseph westermeyer found that peoples in southeast asia had different mating patterns depending on what elevation they lived at — the higher up, the closer the mating patterns (see also here). this pattern appears to be holding true wherever i look (example) — and now we have afghanistan.

here’s a map of the mean inbreeding coefficients for the provinces studied in the two papers above — higher coefficients indicate greater inbreeding (click on map for LARGER view):

Afghanistan provinces - inbreeding coefficients - colored

aaaaand here’s a topographical map of afghanistan. elevation and inbreeding look to match pretty closely (would be nice to have data from the other provinces, too):


here’s a breakdown of consanguinity rates by ethnicity in the country. the numbers are also sorted here by region depending upon which paper they came from — the first paper dealt with the north and east of the country, the second with the south and west. remember that consanguineous marriages include: double-first cousin marriage, first cousin marriage, first cousin-once-removed marriage, and second cousin marriage:

– north & east –
Turkmen = 48%
Hazara = 47%
Uzbek = 44%
Pashtuns = 43%
Tajik (Shi’a) = 43%
Tajik (Sunni) = 38%

– south & west –
Turkmen = 64%
Hazara = 53%
Sadats = 51%
Tajik (Sunni) = 51%
Pashtun = 50%
Tajik (Shi’a) = 49%

the turkmen in the lead!

interestingly, while there is more consanguineous marriage in the south and west of afghanistan, the inbreeding coefficients are higher in the north and east of the country, indicating that there are greater amounts of closer marriages in those (high elevation) regions. and this does appear to be the case — the percentages of double-first cousin marriages are higher in the north and east:

– north & east –
Turkmen = 8.7%
Pashtun = 7.9%
Uzbek = 7.5%
Hazara = 6.4%
Tajik (Sunni) = 6.3%
Tajik (Shi’a) = 4.0%

– south & west –
Sadats – 3.0%
Pashtun – 2.3%
Tajik (Shi’a) – 1.8%
Hazara – 1.2%
Turkmen – 1.2%
Tajik (Sunni) – 1.1%

i’m going to guess that there’s more father’s brother’s daughter’s (fbd) marriage in the north and east of afghanistan rather than in the south and west, since fbd marriage tends to push towards greater amounts of double-first cousin marriage (and, therefore, greater inbreeding in general). i’m also going to guess that the tajiks really don’t practice much fbd marriage at all, either in the north or the south — except maybe for the sunni tajiks in the north.

how long have the various afghani populations been marrying their cousins? dunno. long time prolly. fbd marriage was most likely introduced to the region by the arabs, so the afghanis probably adopted that form of cousin marriage sometime after the mid-600s.

clannishness paradox?

i think that i’m maybe — maybe — starting to notice a paradoxical pattern in clannishness. maybe. time will tell.

and the paradox is: on the one hand, we have peoples who behave clannishly generally favoring their close and extended family members (when they actually live amongst them) over the broader society (the commonweal) — egs. nepotism, corruption, feuding, etc. but on the other hand, i think that those very same clannish people are often more willing than non-clannish peoples to sacrifice one of their own under certain circumstances — it seems especially when it will benefit themselves and/or other members of the extended family/clan. i could be wrong about this. data needs to be compiled.

some examples:

– honor killings: as were discussed in yesterday’s post. and we know from before that honor killings — which are pretty extreme as far as sacrificing a member of the family goes — are most common in the arab world/maghreb/mashriq/afghanistan+pakistan where father’s brother’s daughter (fbd) marriage is preferred and has the highest rates — and fbd marriage pushes towards the highest inbreeding rates.

– the pashtuns: fbd marriage practitioners again. here’s a pashtun proverb via steve sailer:

“When the floodwaters reach your chin, put your son beneath your feet.”

presumably that’s not meant to be taken literally — presumably! but it does sound rather indicative of a willingness to sacrifice even one’s kids if necessary.

– the myddletonians: a middling clannish population from shropshire, england, in the seventeenth century (see here):

“Though placed toward the back of the church, tenant farmers, particularly those who boasted generations of ancestors in the parish, held much honor. They lost this honor, however, if they suffered rituals of public humiliation. So while often ignoring private vices, tenant farmers always made an effort to prevent overt mortifications. Worried middling parents sent their juvenile delinquents far from the surrounding countryside, not to rehabilitate them spiritually or even to save their skins, but to remove their likely and shameful jailings and hangings from the sight and recording of neighbors. A Myddle tavern-keeper, Thomas Jukes, exiled a larcenous son by placing him into apprenticeship with a roving juggler who happened to pass through the village. Michael Brame, of a long-standing Myddle family, came to Myddle following the death of his brother and brother’s wife in order to preserve the family’s leasehold and also to raise his brother’s son William. William robbed meat from several neighbors’ houses. The Braine clan took the only possible action: ‘at last he was sent away,’ noted Gough, ‘I know not whither.’”

disowned. in a serious way!

this all seems rather counter-intuitive — you’d think that clannish peoples would be less willing to sacrifice one of their family members since, most of the time, they seem overly concerned about favoring them. i mean, that’s why their societies are so dysfunctional (to different degrees). but i think it makes a sort-of upside-down-and-backwards sense if you think of these behaviors as altruistic in the strictest biological sense of the word. these behaviors are an example of “inclusive inclusive fitness,” i think. from yesterday’s post:

“you’re not sacrificing your *own* fitness to benefit another’s (whose genes you share), you’re sacrificing *someone else’s* — but you share a lot of genes with them, too, so in a way you *are* sacrificing the fitness of your own genes, just not those in your own person.”

another clannishness paradox that i’ve mentioned before is that individuals from clannish societies often feel very independent. here, for example, is taki on the greeks:

“The highly individualistic Greek is too self-seeking to submit easily to others’ dictates. His unruliness has helped him survive through the centuries of oppression, as well as to rise above adversity. But it has also made him unaware of the advantages of a communal spirit and true democratic attitudes. This has created a climate where cheating is a way of life, where the highest and lowest of citizens do not hesitate to use dishonesty, especially in politics.”

yeah. well, the misunderstanding there is that greeks are “individualistic.” they’re not. they’re clannish. and because they’re clannish, they don’t like outside interference — they’re not going to “submit easily to others’ dictates” and they’re certainly not going to have “a communal spirit and true democratic attitudes.” clannish people — like southern libertarians — don’t want outside interference (like from the gub’ment), so they seem individualistic, but what they are, in fact, is independent-minded — but in a clannish sort of way. the true individualists — the non-clannish peoples — tend to be communally oriented. and they are rare.

paradoxical, no? (^_^)

who wants sharia?

pew has just released the results of their latest survey of muslims around the world (in 39 different countries).

here’s a map showing the percentage of muslims in each country that would like sharia to be the law of their land (click on map for LARGER image – should take you to the pew site):

who wants sharia - pew 2013

the iraqs, afghanis, and pakistanis all seem pretty eager for sharia — they’re all in the 75-100% range. the moroccans, too. and the palestinian territories.

this is a large report from pew, so have a look at the whole thing yourself.

here’s something else that i found particularly interesting:

honor killings permissible - pew 2013

of the countries that think that honor killing is more justified when women commit an offense than when men do — russia, albania, azerbaijan, bangladesh, pakistan, jordan, iraq, egypt, lebanon, tunisia, and the palestinian territories — a majority of them (7 out of 11) have a preference for father’s brother’s daughter’s (fbd) marriage — pakistan, jordan, iraq, egypt, lebanon, tunisia, and the palestinian territories.

i don’t know what, if any, form of cousin marriage is preferred in azerbaijan or bangladesh. paternal cousin marriage, which would include fbd marriage, is avoided in places like chechnya and (at least among some peoples in) dagestan (russia in this survey?) and albania. the difference in the responses in albania was not very great (+1 point), but the difference in russia(?) was statistically significant at +7 points. it’s difficult to know who these “russian” muslims are (maybe the info is in an appendix somewhere — i’ll have to look), so i don’t know if they’re the chechens and/or some dagestanis and/or some other group(s) — and, so, i don’t know what their mating patterns are.

i’m surprised that afghanistan breaks even. i would’ve predicted that they would be like the other fbd marriage groups.

it’s interesting that some of the central asian “stans” — kyrgyzstan and uzbekistan — swing in the opposite direction. a greater number of people feel that honor killings are more justified against men who break the rules than women. i don’t know much of anything about these populations, but i did read a bit just the other day, and it seems that they have a preference for maternal cousin marriage. (note that i don’t have a good idea what the rates might be.)
