In this study, we use data of the German Mikrozensus to explore first and second birth behavior of migrants' descendants. Whereas prior waves of the Mikrozensus only included respondents' citizenship, in the survey years 2005 and 2009 also parental citizenship has been surveyed. This allows us to identify respondents' migrant backgrounds, even if they have German citizenship. We distinguish those who migrated as children (1.5 generation) from those who were born to Turkish parents in Germany (second generation migrants). We compare both migrant generations to German non-migrants. Using discrete-time hazard models, our results show that 1.5 generation migrants have the highest probability of having a first and second birth, while German non-migrants have the lowest birth probabilities. The second generation lies in-between. This pattern also persists after taking the educational attainment of respondents into consideration. However, there seems to be an adaptation of highly educated second generation Turkish migrants to non-migrant Germans: we find no significant differences in the probability of having a first birth in the two groups. For second births, we do not find this pattern which might be related to the young age structure in the sample of second generation migrants.
在本研究中，我们使用德国微观人口普查数据来探究移民后代的头胎和二胎生育行为。之前几轮微观人口普查仅涵盖受访者的公民身份，而在2005年和2009年的调查年份中，还对父母的公民身份进行了调查。这使我们能够确定受访者的移民背景，即使他们拥有德国公民身份。我们将儿童时期移民的人（1.5代）与在德国出生的土耳其父母的子女（第二代移民）区分开来。我们将这两代移民与德国非移民进行比较。使用离散时间风险模型，我们的结果表明，1.5代移民生育头胎和二胎的概率最高，而德国非移民的生育概率最低。第二代移民则介于两者之间。在考虑受访者的教育程度后，这种模式仍然存在。然而，受过高等教育的第二代土耳其移民似乎在向非移民德国人转变：我们发现两组生育头胎的概率没有显著差异。对于二胎生育，我们没有发现这种模式，这可能与第二代移民样本中的年轻年龄结构有关。
