Should the UK Government Expand Pro-Marriage Tax Relief?

In April 2015, David Cameron’s government implemented legislation to promote marriage by providing tax relief for low-income married couples. While nearly four million couples could potentially claim the benefit of around £212 per year, it has been difficult to obtain and relatively few have done so. Now the government has plans to expand these tax benefits to more married couples in order to “send a strong signal that we back marriage.” (Cameron 2014) This raises the question of whether marriage, compared to cohabitation, does indeed boost well-being, and whether incentives to marry need to be expanded.

A large body of research has shown that marriage is associated with better health, wealth, life satisfaction, and life expectancy (see Waite and Gallagher 2002 for a review). However, these associations may be the result of selection effects, or the characteristics of the individuals who choose to marry or cohabit. Once selective characteristics are taken into account, the benefits to marriage may disappear.

In addition, cohabitation has increased rapidly in the UK over the past few decades, potentially providing many of the same advantages as marriage. Cohabiting unions are becoming more prevalent and lasting longer (Beaujouan and Ni Bhrolchain 2011). Cohabitation is also becoming more common as a relationship for childbearing; 30% of all births in 2012 occurred to cohabiting women (ONS 2013). Thus, while cohabiting unions are quite heterogeneous and often end in dissolution (Berrington et al 2015), some may provide the same benefits as marriage.

Marta Styrc and I have recently used the 1970 British Cohort Study to investigate whether the mental well-being of cohabiting and married people differed at age 42, after most people had completed childbearing (CPC Working Paper 75). The mental health indicator – the Warwick-Edinburgh Mental Well-being Score – captured multiple dimensions of happiness and contentment. We examined whether early childhood characteristics (potential sources of selection) account for differences between married and cohabitating men and women. We paid particular attention to those in long-lasting relationships and with joint children.

Using Propensity Score Matching, we found that childhood background characteristics – family structure and socio-economic status; adolescent cognitive abilities and educational aspirations; and adolescent psychological attributes – completely eliminated any mental well-being differences between cohabiting and married men and women. On the other hand, childhood background characteristics were insufficient for removing differences between those living with and without a partner, regardless of marital status. While we were unable to control for developments in adulthood or current factors that may influence well-being, our results nonetheless suggest that living with a partner matters.

Thus, our findings imply that the UK government should not be attempting to promote marriage as much as it should be fostering healthy partnerships in general. Our study shows that the type of partnership is irrelevant. What really matters for adult well-being is early childhood conditions – whether parents struggled financially, divorced, or smoked during pregnancy – and adolescent psychological behaviors and cognitive development, such as educational aspirations and self-esteem. Thus, alleviating childhood poverty and educational disparities, and improving mental health care would go much further in reducing well-being inequalities than focusing on marriage.

Dr. Perelli-Harris is Associate Professor at the University of Southampton. Previously she was a Research Scientist at the Max Planck Institute for Demographic Research in Rostock, Germany and a post-doc at the University of Wisconsin. She completed her Ph.D. in Sociology at the University of Michigan in 2006. Dr. Perelli-Harris currently holds a five-year European Research Council starting grant to study the increase in childbearing within cohabitation in industrialised countries (www.nonmarital.org). Working with researchers across Europe, the USA and Australia, she uses demographic techniques, quantitative methods, and qualitative approaches to explore the underlying reasons for the development of new family formation behaviours, as well as their impact on society. Recently, she has edited a Special Collection in Demographic Research “Focus on Partnerships: Discourses on cohabitation and marriage throughout Europe and Australia.”
