Household fatherhood (living with a partner and her children) is increasingly common, which also increases the types of family situations men can choose. This paper examines factors distinguishing men's partnership and parental statuses in the United States and Sweden. These countries differ in state support to families. Unlike the United States, in Sweden the presence of a man in a relationship with a woman with children has little effect on receipt of alternative forms of income support and health insurance, lowering the cost of men's membership in families. We examine how resources (earned income and education) affect men's family relationships in these two countries.
