They analyzed data about well-being from two national surveys in the United Kingdom and the Gallup World Poll. In all but a few parts of the world, even when controlling for people’s life satisfaction before marriage, being married made them happier. This conclusion, however, did not hold true in Latin America, South Asia and sub-Saharan Africa.
Intriguingly, marital happiness long outlasted the honeymoon period. Though some social scientists have argued that happiness levels are innate, so people return to their natural level of well-being after joyful or upsetting events, the researchers found that the benefits of marriage persist.
One reason for that might be the role of friendship within marriage. Those who consider their spouse or partner to be their best friend get about twice as much life satisfaction from marriage as others, the study found.
The effect of friendship seems to be the result of living with a romantic partner, rather than the legal status of being married, because it was as strong for people who lived together but weren’t married.
