Relationships and community: statistics

Relationships are one of the most important aspects of our lives. People who are more socially connected to family, friends, or their community are happier, physically healthier, and live longer, with fewer mental health problems than people who are less well connected. 

It’s not just the number of friends you have, and it’s not whether or not you’re in a committed relationship, but it’s the quality of your close relationships that matters. Living in conflict or within a toxic relationship is more damaging than being alone.

Family and childhood

  • Childhood circumstances such as poor attachment, neglect, abuse, lack of quality stimulation, conflict and family breakdown can negatively affect future social behaviour, educational outcomes, employment status and mental and physical health.399 Conversely, children and young people with good personal and social relationships with family and friends have higher levels of well-being.1,2
  • A 2015 survey of children attending child and adolescent mental health services found that family relationship problems were the single biggest presenting problem.3
  • Preventative interventions with parents that focus on their relationship as a couple can help to enhance children’s well-being and reduce emotional and behavioural difficulties.4,5

Couple relationships

  • Being happily married or in a stable relationship impacts positively on mental health. Research has found that high marital quality is associated with lower stress and less depression. However, single people have better mental health outcomes than unhappily married people.6
  • Recent studies from Ireland and the USA have found that negative social interactions and relationships, especially with partners/spouses, increase the risk of depression, anxiety and suicidal thoughts. In contrast, positive interactions reduce the risk of these issues.7,8


  • People in neighbourhoods with higher levels of social cohesion experience lower rates of mental health problems than those in neighbourhoods with lower cohesion, independent of how deprived or affluent a neighbourhood is.9
  • Neighbourhood social cohesion was associated with a reduction in depressive symptoms in older people.10
