PhD project on singlehood and the social embeddedness of singles at NIDI-KNAW

The rise in singlehood is one of the major demographic trends of the last few decades. The question is how to maintain social cohesion in this context of increasing individualization. This PhD project examines whether and under which circumstances singlehood has integrative or isolating effects for singles aged 20 to 50. It explores what it means to be single, as well as singles’ social relations and well-being. It does so by collecting and examining new qualitative and quantitative data among singles and by using large-scale register data on networks. The focus of the project is on diversity within the singles’ population.

Key research questions include:

  • What does it mean to be single?
  • How do the social networks of singles differ from those of partnered individuals? Does this change over the life-course?
  • Under which individual and contextual conditions does singlehood foster integrative versus isolating patterns of social relations and solidarity behavior?
  • To what extent do perceived singlehood norms within family, workplace, and neighborhood contexts moderate the relationship between singlehood and well-being, and are these effects gendered?

This PhD project is part of the SOCION consortium. SOCION addresses a pressing challenge of our time: fragmentation in societies. Social cohesion is society’s fabric and is key to sustainable societies and citizens’ well-being. However, it is increasingly undermined by erosion and polarization between communities, factions, and groups. In this project, psychologists, social historians, demographers, philosophers, and sociologists collaborate with civic organizations to generate and integrate insights into how connections between individuals, groups, and institutions contribute to new pathways to and forms of social cohesion.

This PhD-project will be supervised by Lonneke van den Berg (daily supervisor), Matthijs Kalmijn (promotor), and Charlotte Knowles (RUG-philosophy).
