This contribution investigates how religion retarded the Dutch fertility transition by looking at how denominations were associated with the timing of first births (starting), the length of birth intervals (spacing), and the timing of last births (stopping). First, we apply a simple descriptive model of starting, spacing, and stopping to life-course data from the province of Utrecht. Then, we apply multivariate regression to assess the independent effects of religious denominations, net of socio-economic status, on stopping behaviour. The results indicate that liberal Protestants were more prone to adopt stopping behaviour than orthodox Protestants and Catholics.
