Summary
In this paper a method for decomposing rural-urban fertility differences into separate differences in nuptiality and marital fertility is developed. This technique is applied to national and provincial statistics for two countries, Japan and Sweden. It is shown that there are some features of rural-urban differences which hold for both countries, but it is also demonstrated that because the Japanese and Swedish fertility transitions were markedly dissimilar, there are salient contrasts in the relation between the magnitude and composition of the rural-urban differences and the stage reached in each country during its fertility transition.
