Song Wu-chul et al. wrote a paper ("Female-to-male proportions of the head and face in Koreans" 2009) about cranio-facial dimensions in Koreans belonging to three different age groups (20-39, 40-59, 60-79). While the numbers in this papers might give a clue to the question in the headline of this thread, there is not enough information about the materials and methods of the team, which is, btw, not known to me from any other studies. I.e., I fear, it could be one of those teams prone to rookie mistakes. Especially since the total sample consists of no less than 3337 people, some more description and, possibly, splitting according to birth place, profession etc should have been done for the sake of better control. - head length: didn't change much in the women. But, strangely, the youngest cohort of the male samples was reported to have significantly longer heads than the older male samples. That said, the head length of the youngest male cohort seems to be more compatible with the head lengths of all three female cohorts (about 1cm more). So I wonder which cohort was measured where and by whom. But, as usual today, this kind of important data is missing. Anyway, in case that the data for the youngest male cohort are correct and perfectly comparable, one will have to ask whether the head just got bigger or the occiputs suddenly started jutting out. Judging from the data of which I'm aware (246 on average long-headed Gyeongsang-namdo Koreans had been reported by Kohama et al. in 1940), my guess is that head length didn't change much. - head width: constantly increasing - "total" head height: constantly increasing - facial width: largest in the intermediate generation; i.e., indicating that the face keeps on growing during adulthood. Two reasons for the older cohort being more narrow-faced are imaginable: facial width growth could be dependent on nutrition to a mild degree. 2) Behavioural correlates could have affected life expectancy of broad-faced Koreans. 3) Changed soft tissue thickness could have altered facial width at the zygia. 4) Different anthropometrists were at work. 5) The age cohorts were from different places and/or social groups. I favour the second and third explanations because there is no evidence from reknown anthropometrists for the first one. On the other hand, the facial width data don't seem to contradict each other as much as in head length data. - facial height: NOT reported (go figure why...) addendum in red Edited by black man, Apr 27 2018, 04:41:00 PM.

Hmm. I actually read a Korean article that described Korean male faces becoming shorter than before (due to the chin area becoming smaller and shorter), so I’m not sure what they mean by “longer faces” in this study. Perhaps by “longer”, they mean “narrower”? I think that’s possible among the young generation especially, but also at the same time we have this phenomenon of a greater number of overweight Korean males with superficially ‘wide’ faces. So I’m not quite sure how to summarize this current phenomenon of changing Korean faces. |

Also, speaking honestly I don't really find Koreans to have much wider faces than Chinese on average. And to be even more honest, both populations overlap much more than what people would expect them to be. I've lived in major U.S. cities. I've even worked in Chinatowns. It appears to me that the robust faces are found in every sinid population. Edited by luxemen, Apr 27 2018, 03:29:14 PM.

Koreans do indeed have wider, longer, flatter faces on average. Many Chinese have wide faces, but the face is usually short and nose wide, where as Koreans tend to have long, wide faces with narrow noses. ![]() Longer head is measuring the front-to-back of the head. It generally leads to a narrower, more 3-dimensional face but doesn't always. Edited by ren, Apr 27 2018, 04:04:37 PM.

Ok, I can't disagree with your description there. Thanks for your clarification. I was writing more in response to the notion that all Koreans have block-heads, because that's not entirely true either. Edited by luxemen, Apr 27 2018, 04:05:23 PM.

In terms of "block heads" (Kim Jun-en), there are definitely more Koreans of this type than Chinese, but some group like Mongolians would have even more. It's all relative and for Koreans, porbably don't represent the majority. Some Chinese have very small faces and the overall average would definitely be significantly different from Koreans.

I'm from a small-faced overseas southern Han Chinese family. And prior to the Korean pop wave, I almost exclusively knew Koreans from action movies which mostly featured relatively large-faced and generally rather robust men. The first time I came across relatively many small-faced Koreans was at university. As far as I remember the pictures I found back then in the internet, I suppose, there could be certain faculties at which there are more small-faced Koreans. Could this be the case, Nurizone? I mean, there can be selection mechanisms according to social backgrounds, temperaments etc at different faculties. And if the latter correlate with facial features, that would be a noteworthy phenomenon. In such cases anthropometric studies on features of students at one faculty or at one type of faculty only would probably not be representative for the average population of a country as a whole. |
