Growth and Aging, and Correlations between Kinsmen in Head Length and Breadth of Tobishima and Aoshima Islanders

Abstract

Tobishima and Aoshima are small islands in the Japan Sea, about thirty kilometers off the west coast of the Tohoku district of Japan.
General remarks on their measurements and indices (Table 1-4) are as follows; on the means, there are no marked differences between both islanders, and on the variation coefficients, the fluctuations during growth and aging are not so noticeable as that in measures like stature.
Then, to remove the influences due to sex and age from the correlation coefficients, individual measurements were converted into standardized values (Table 5) taking percentages for each mean.
The average of correlation coefficients (Table 6) calculated on the standardized values, are about 0.25 between Ego and palent, 0.40 between Ego and brother or sister, 0.05 between Ego and grandparent, 0.10 between Ego and uncle or aunt, and 0.05 between Ego and cousin.
