Having a Partner or Living with a Partner: Differences in Life Satisfaction and Mental Health

Using longitudinal data from Australia we compare the wellbeing effects of transitions both into and out relationships, using two different measures of wellbeing: life satisfaction and mental health. We distinguish between the formation, and ending of, three different types of relationships across three years: Living-apart-together (LAT), cohabitations, and marriages. For those in LAT relationships, we find they are quite distinct from other ‘single’ people. Starting, or ending, a LAT relationship has a significant impact on an individual’s wellbeing. We also find that transitions into relationships, and transitions out of relationships, do not have equivalent effects. Generally, moving from a relationship to being single had a more significant negative impact on life satisfaction and mental health, than moving into a relationship had a positive impact. These findings suggest that having an intimate partner, even one who is not co-resident, is related to higher levels of wellbeing compared to having no partner.
