Background: A plethora of emergent literature is investigating the prevalence of gender preferences among immigrant communities in Western industrialized countries. Such research not only sheds light on fertility preferences of immigrants but also unearths immigrant assimilation versus persistence processes. Germany has a long history of immigration but has maintained an ethnic assimilationist regime. Turkish immigrants form the largest immigrant community in Germany. We investigate the extent to which Turkish immigrants in Germany mirror the fertility preferences of the native population. Objective: We analyse whether the gender of the first and, subsequently, gender of the first and second child affect transition to second and third births, respectively, for non-immigrant and immigrant (Turkish) women in Germany. We further assess whether the significance of gender as a determinant of fertility progression varies across subsequent generations of immigrants. Methods: We use Waves 1 and 2 of both the main German Generations and Gender Survey and the supplementary German-Turkish Generations and Gender Survey. We apply Kaplan‒Meier survival analysis and Cox regression models to the non-immigrant (native) and immigrant (Turkish) sample in order to examine transitions to second and third births by gender of the first and first two children and immigration status. Results: We have two main results. First, Turkish immigrants in Germany exhibit son preference at the second and third birth parity. Second, son preference declines across subsequent generations of Turkish immigrants in Germany. Conclusions: Although our results suggest that fertility preferences of Turkish immigrants in Germany converge with those of the native population over subsequent generations, we cannot conclusively deduce this given the unique nature of our data.

性别偏好和生育率：调查德国的土耳其移民案件

背景：大量新兴文献正在调查西方工业化国家中移民社区中的性别偏好发生率。这样的研究不仅揭示了移民的生育偏好，而且揭示了移民同化与持续过程。德国拥有悠久的移民历史，但一直保持着民族同化政权。土耳其移民是德国最大的移民社区。我们调查了德国的土耳其移民在多大程度上反映了当地人口的生育偏好。目的：我们分析了德国的非移民和移民（土耳其）妇女的第一胎和第二胎的性别是否分别影响到第二胎和第三胎的过渡。我们进一步评估了性别作为生育能力发展决定因素的重要性是否在后代移民中有所不同。方法：我们使用了主要的德国世代和性别调查以及补充的德国-土耳其世代和性别调查的第一波和第二波。我们将Kaplan（Meier生存分析和Cox回归模型应用于非移民（原住民）和移民（土耳其）样本，以便根据前两个孩子的性别和移民状况来检查到第二胎和第三胎的过渡。结果：我们有两个主要结果。首先，德国的土耳其移民在第二和第三胎出生时表现出对儿子的偏爱。其次，儿子的偏爱在德国的后代土耳其移民中有所下降。结论：
