This study examines three hypotheses on urbanism and kinship. The subcultural hypothesis predicts that the increasing selectivity of the overall social networks accompanied by urbanism reduces the size of kinship. The modified subcultural hypothesis claims that the urban effect holds true only for those who grew up in the same metropolitan area. The 'decreasing number of children' hypothesis implies that the effect is spurious simply because urbanites have a smaller number of children and siblings. Results of this study's analysis of Nagoya Metropolitan Survey data indicate that the number of intimate kin decreases with urbanism, even after adjusting for marital status and education. However, this holds true only for those who grew up in the metropolitan area considered, and it is not fully explained by the decreasing number of children and siblings they have. Therefore, the modified subcultural hypothesis is supported by the data. Additional analysis, however, suggests that the contingent effect of urbanism is due to the emancipation from extended kinship groups as the result of geographical diffusion of relatives, instead of the increasing selectivity of the overall networks.
