in the interests of k.i.s.s. k.i.s.s., i decided to look again at mating patterns and family types in the murdock ethnographic atlas, but this time looking just at exogamous, agamous and endogamous mating practices without all the cousin-marriage business.

so, what i looked at this time were just what sorts of “domestic organizations” (nuclear/stem, polyandrous/polygynous, extended families) go with different “community marriage organizations” (exogamous, agamous, endogamous). (see previous post for explanations of all those categories.)

i got results for 184 societies. as in the previous post, i collapsed nuclear & stem families, small & large extended families, and the various exogamous & endogamous categories together. this time i left in the polygynous/polygamous family types and the agamous mating patterns. here’s what i found (click on chart for LARGER view):

again, nuclear and stem families just do not go together with endogamous mating patterns. you need exogamous or agamous (not caring one way or the other) mating patterns to get nuclear or stem families. there is clearly a relationship between endogamy and extended families.

also, there seems to be more endogamy in the world than exogamy. and quite a lot of peoples who don’t seem to be able to make up their minds on the issue.

for the record, the two murdock atlas societies that are endogamous AND have nuclear or stem families (there’s one of each) are:

- the ahaggaren tuareg tribe (endogamous marriage patterns with nuclear families)
- the konso people of ethiopia (endogamous marriage patterns with stem families, occasionally polygyny).
