Living together in old age makes people happy - Marriage is secondary - Living Together—Not Marriage—Boosts Happiness for Older Adults, Study Finds

A large international study has found that older adults who live together report higher levels of happiness and well-being. The research, involving 2,840 people aged 50 to 95, shows that sharing a home boosts life satisfaction—whether couples are married or not. Surprisingly, tying the knot later in life does not add to their contentment.

The study tracked how different relationship changes affected older adults. Those who started a new partnership and moved in together saw a clear rise in life satisfaction. Even after a breakup, participants showed resilience, with no drop in their overall happiness.

In Germany, unmarried cohabitation has gained wider acceptance over time. These partnerships now hold similar legal standing to marriage in many areas, such as joint custody of children if both parents agree. However, tax and social insurance rules still treat unmarried couples as individuals. Same-sex marriage became legal in October 2017, replacing earlier registered partnerships.

Societal attitudes have shifted as education and cultural changes promote diverse family structures. Earlier generations often viewed marriage as the only stable and economically sound option. Today, debates continue over tax policies that could better support unmarried partners.

The findings suggest that sharing a home matters more for older adults' happiness than formal marriage. Starting a relationship and cohabiting brings measurable benefits, while breakups do not reduce well-being. These results reflect broader societal changes in how relationships are valued and structured.
