This study examines differences in the timing of birth between migrants and non-migrants drawing on retrospective event history data. The analysis employs the Andersen and Gill, or AG model, for repeated events is a statistical model used to compute “Marital Duration-Specific Fertility Rate”. The results show that after 21 years of marriage 17% of migrants had never given birth, whereas at the same time only 11% of non-migrants had never given birth. Migrants have a smaller chance of giving birth than do non-migrants. The median time to a birth is 2.11 years for non-migrants and 2.77 years for migrants. In addition, the findings show that the likelihood of having a birth decreased by 21% for current migrants compared to non-migrants. The statistical model shows that education and occupation have powerful effects on fertility. The results confirm the hypotheses of selectivity, disruption, and adaptation effects of migration on fertility.
