“…These family changes have been viewed as evidence that marriage is undergoing deinstitutionalization, which has been defined in terms of the rise of marriage alternatives and a decline in the dominance of marriage (Cherlin 2004(Cherlin , 2020 as well as the lesser governance of spouses' behaviors by social norms (Cherlin 2004(Cherlin , 2020Lauer and Yodanis 2010). An alternative perspective is diversification, which does not focus on understanding family change in terms of the marital institution but in other ways, including personal life and relationships (for a comprehensive discussion, see Knapp and Wurm 2019). However, putting aside questions of whether alternatives to marriage (i.e., contexts external to the institution) should be interpreted in terms of deinstitutionalization or diversification, in this paper we focus on a less-studied aspect of marriage, namely, how social, economic, psychological, and personal dimensions of the marital experience, or what might be considered features of the internal context of marriage, are changing over time and across relevant stakeholders.…”
