Turkish migrants differ in their fertility and marriage behavior from native Germans. These differences, especially those concerning the link between the two events birth of the first child and first marriage, will be examined in this article by using event history analysis with data of the Generations and Gender Survey from 2005 (main survey) and 2006 (additional survey of Turkish nationals). We address the question to what extent the link between first marriage and starting a family differs between these two groups and if the differences are accounted for by religious or educational differences. The key findings are: Germans often marry between getting pregnant and getting their first child. Turks, however, predominantly get pregnant within marriage. Turkish women who get pregnant before marriage have subsequently worse prospects on the marriage market. These differences are not accounted for by religious and educational differences. It can be assumed, however, that differences between Islam and Christianity are relevant.
