Social-class differences in spacing and stopping during the historical fertility transition: Insights from cure models

BACKGROUND There is a long-standing debate about the role of spacing and stopping in the fertility transition, which has been fueled by lack of methods to appropriately model spacing and stopping. Traditional event-history analysis cannot distinguish the two processes in analyzing the determinants of birth risks and attempts to separately model spacing and stopping have been criticized from a methodological point of view. OBJECTIVE Our aim is to assess the role of spacing and stopping in the historic fertility transition more generally, and for social-class differences in fertility decline, more specifically. METHODS We use cure models, which are extensions of traditional survival analysis, to distinguish the impact of stopping and spacing on fertility. The models are applied to individual-level data for a region in southern Sweden between 1813 and 1967. RESULTS Both spacing and stopping played a role in the fertility transition, but stopping emerged earlier for all parities after the first and had a greater effect on the reduction in fertility. Higher social classes were forerunners in the fertility transition but we do not find that spacing and stopping operated in different ways by social class. CONCLUSIONS Our findings indicate that stopping had an earlier and more substantial impact on the fertility transition than spacing. However, the patterns of the two behaviors were highly similar between social classes. CONTRIBUTION Our study is one of very few that applies cure models to distinguish spacing and stopping in the fertility transition, and the first to our knowledge that use this approach to study class differences in the fertility decline.
