The mean inbreeding coefficients for Gyoda and Hasuda cities were 0.00295 for 600 couples and 0.00320 for 621 couples, respectively. The mean inbreeding coefficient decreased and the mean marital distance increased with a more recent year of marriage. The mean distances and its standard deviations between birthplaces of mates, father-offspring, mother-offspring, and sibs are 53.95 +/- 159.30 km, 43.38 +/- 174.29 km, 37.61 +/- 131.32 km and 9.42 +/- 66.39 km, respectively for the Gyoda population. These values are 98.49 +/- 270.77 km, 87.60 +/- 249.91 km, 60.05 +/- 193.63 km, and 16.36 +/- 64.64 km, respectively for the Hasuda population. The dimensionality of migration seems to be one.
城田市和莲田市600对夫妇的平均近亲繁殖系数分别为0.00295，621对夫妇的平均近亲繁殖系数分别为0.00320。近亲繁殖系数均值随着结婚年份越近而降低，平均婚姻距离则增加。城田市配偶出生地之间、父母与子女之间、同胞之间的平均距离及其标准差分别为53.95±159.30千米、43.38±174.29千米、37.61±131.32千米和9.42±66.39千米。莲田市的这些数值分别为98.49±270.77千米、87.60±249.91千米、60.05±193.63千米和16.36±64.64千米。迁移维度似乎为一。
