Research on loneliness

This page on loneliness is part of a new initiative to help people in Wales access research on topics related to social care. The research is chosen or ‘curated’ by people who have professional experience of research in the topic area.

What is loneliness?

A widely used definition of loneliness was developed by Jenny De Jong Gierveld in 1998:

‘Loneliness is a situation experienced by the individual where there is an unpleasant or inadmissible lack of quantity or (quality of) certain relationships. This includes situations in which the number of existing relationships is smaller than is considered desirable or admissible, as well as situations where the intimacy one wishes for has not been realised. '    

This means that someone can have a small group of friends and never experience loneliness because they meet their needs. Or alternatively, someone can have a large group of friends and still feel lonely because those relationships are not as numerous as they’d like or they are not the quality of relationship they desire.

Social isolation is different, and is defined as the absence of contact with other people. Loneliness, on the other hand, is a natural phenomenon and most people will feel lonely at some point in time. Loneliness becomes a problem when it goes on for a long period of time – this is called ‘chronic loneliness’.

Loneliness over a long period of time is harmful to our physical and mental health. Researchers have found that loneliness has been linked with an increased risk of developing coronary heart disease and strokeand with an increased risk of high blood pressure. Research in the US found that loneliness increases the risk of dying early by 26%. Loneliness is also associated with an increased risk of mental health problems such as depression.

Loneliness in Wales

Data from the 2016-17 National Survey for Wales found that around 440,000 or 17% people report being lonely in Wales. The National Survey for Wales also found that poverty was a factor in loneliness with 37% of those in material deprivation being lonely. In comparison, only 12% of those who weren’t materially deprived (12%) reported being lonely.

Loneliness is more commonly associated with later life, even though it can be experienced at any age.

In fact, the data from the National Survey shows that in Wales more people between 16-44 are lonely than older people.

At the same time, the data from the Analysis of interim data from the Maintaining Function and Well-Being in Later Life study (Cognitive Function and Ageing Wales) found that among older adults (65+) participating in the study 24.3% were lonely and 29.6% were isolated.
