Socioeconomic differentials in multi-partner fertility among fathers

Changes in family structures and changing gender roles have brought more attention to fatherhood and men’s role in fertility decisions. Yet, fertility research has been highly gendered with focus on women’s childbearing. More men than women remain childless, with an increasing gender gap over the cohorts, and there is increasing propensity to have children with more than one partner. Our data are administrative register-data of Norwegian men born 1935-1967 (N≈1.2 mill.). We will use a discrete hazard rate model with a two-step procedure: First we will analyse the risk of having a first birth versus no birth, and second we will model the competing risk of having a higher-parity birth with a new partner (multi-partner fertility), a higher-parity birth with the same partner, or no more children. We will include marital history, educational characteristics (both level and field) and environmental factors (family background and region of upbringing).
