This study aims to contribute to the literature by examining the association between war-induced migration and fertility behaviors through an analysis of women fleeing into Türkiye from Syria, including residents in the destination country, using theoretical frameworks of disruption and adaptation hypotheses. The 2018 Turkey Demographic and Health Survey—Türkiye and Syrian sample data are used within the framework of a life course approach. Discrete-time logistic regression models are used, wherein Syrian refugee women are covered first before the Türkiye sample is added to the modeling. The findings indicate no disruptive effects of migration on fertility outcomes of women among forced migrants compared to non-migrants in a specific year, indicated by a statistically insignificant association between migration and fertility among Syrian refugee women. Finally, no adaptation of fertility of Syrian refugee women to the native population in Türkiye is observed.
