The Trajectory of Subjective Well-Being: A Partial Explanation of the Marriage Advantage

Although several studies have documented a distinct marriage advantage in well-being, it is still unclear what it is about marriage that renders this benefit. We hypothesize that it is due to factors theorized to accrue to matrimony, such as elevated financial status and specific social psychological supports. We examine the trajectory of subjective well-being for 1,135 respondents from the three-wave 2010 GSS panel survey utilizing linear mixed-effects modeling. We find that about two-fifths of the marriage advantage in subjective well-being is accounted for by a mixture of control variables, finances, and emotional factors, with most of this due to elements that are associated with the marital context. Higher annual income, enhanced interpersonal trust, greater sociability, and less of a sense of loneliness and isolation appear to be responsible for a substantial component of the marital advantage. We further find that the marriage advantage is invariant to both race and gender.
