This chapter considers empirical evidence about the effective socialization of the home—that is, a stable marriage—in the lives of adult children. Social scientists have mapped the trajectory of marriage from its status as an institution to its voluntary and tenuous existence today. This chapter considers how the good of stable homes are socialized and transmitted from parents to children, while highlighting the challenges facing marital socialization today. The evidence suggests parents’ marriage and home dynamics still matter for what happens in their adult children’s lives. Where parental marital security is maintained, and especially where a legacy of familial warmth is experienced, optimal outcomes are still apt to flow to children both in the near term and the future.
