The intergenerational transmission of first birth timing in Norway

In our study we will address this problem in three steps and give new insight into the intergenerational transmission of first birth timing. We use Norwegian register data, including information from over 300.000 women born in 1954-64 and their mothers. We will first run ordinary Cox proportional hazard regressions to test for the existence of a transmission effect of timing of birth between mothers and their daughters. In a second step, we will include family fixed-effects to make within-family comparisons of how mother’s age at birth of daughter A affects daughter A’s age at first birth. The fixed-effects method allows us to control for all non-measured stable characteristics at the level of the family in a model of the transmission of timing of birth. In a third step we will examine how censoring and unequal censoring times within the family affect results in family fixed-effects models.
