Until 2008, Germany’s vital statistics did not include information on the biological order of each birth. This resulted in a dearth of important demographic indicators, such as the mean age at fi rst birth and the level of childlessness. Researchers have tried to fill this gap by generating order-specifi c birth rates from survey data, and by combining survey data with vital statistics. This paper takes a different approach by using Perinatal Statistics to generate birth order-specific fertility rates for the period 2001 to 2008. Perinatal Statistics includes information on births that took place in German hospitals. Out-of-hospital births, which account for about 2 % of all births, are not included in the Perinatal Statistics. In a sensitivity analysis, we show how robust our estimates are to the inclusion of out-of-hospital births. Our general assessment is that the Perinatal Statistics is a valuable source for generating order-specific fertility rates, regardless of whether out-of-hospital births are included
