This study first examines the relationship between partnership status and subjective well-being in 45 European countries by analyzing the European Values Study 2008. It was expected and empirically confirmed that married individuals have the highest level of well-being, followed by (in order) cohabiting, dating, single, and finally widowed and divorced individuals. In addition, this study examines to what extent the well-being gaps depend on the normative climate in which an individual lives. It is hypothesized that: (a) being in a non-married relationship (especially cohabitation and divorce) lowers well-being compared to being married in societies that reject non-traditional partnership statuses; and (b) not having a partner is especially detrimental for well-being levels in familialistic societies, which emphasize the importance of a strong, close-knit family. The normative climate appears to hardly affect well-being gaps between partnership statuses. Only the gap between divorced and married women is significantly wider in familialistic societies. It is concluded that the weak dependence of well-being on the normative climate may point at high autonomy in private, relationship-related decisions.
