[영문]Previous studies of the marital fertility transition in Europe have found religious differentials. Using data collected from the population registers of The Hague, our aim in this study is to search for answers to the following questions: whether religious differentials result from socio-economic characteristics; to what extent religious ideology explains the behaviour of religious groups; which proximate determinants account for the religious differentials; and whether the Jews were forerunners in the marital fertility transition in Europe. The results provide some evidence of relatively low levels of parity-dependent fertility control among Jews before the transition and among Catholics during the transition. Religious ideology probably accounts for the low level of fertility control among Catholics. The ultimate reason for the relatively high marital fertility among Jews before the transition remains unclear. Our findings do not support the hypothesis that Jews were forerunners in the marital fertility transition.
