During the last decade, a continuous increase in the rate of stillbirths has been observed in Germany. So far, the reasons for this trend are not well understood. It is conceivable that the rising stillbirth rate is explained by demographic changes. For instance, the age of the woman giving birth has an impact on the risk of stillbirth—with increased risks in teenage pregnancies and pregnancies of women over 35 years of age. Furthermore, there is empirical evidence of higher stillbirth rates among immigrant women. An increase in births in higher-risk populations could therefore influence the overall stillbirth rate. The aim of this study is to quantitatively assess whether the increasing stillbirth rate in Germany is attributable to structural changes in the population with regard to the age and nationality of women giving birth.
