A Comparative Perspective on Male Fertility Trends

Keywords: Fertility Development; Data and Surveys

We have a good understanding of fertility trends among women, but there is little comparative research on fertility trends among men. However, the small number of existing studies on men suggest that global variation in male fertility is much higher than global variation in female fertility.

The projects in this research area aim to provide a comparative perspective on male fertility trends in high-income countries. One emphasis is on compiling data on long-term trends in male fertility from official statistical sources. While official statistics often provide for almost all births information on the mother, information on the father is frequently lacking for a non-negligible number of cases. A focus of this research area is on developing and testing methods that aim to impute missing data on the father, conditional on information available on the mother. The derived datasets allow us to bring comparative investigations of the relationship between male and female fertility trends to a new level. We investigate fertility outcomes, fertility timing, and age differences between the parents. The raw and imputed data are intended to be made available to researchers as part of the Human Fertility Collection.
