Eight thousand older adults in England are having their DNA scanned alongside decades of detailed data on their savings, trust in neighbours, and leadership roles. This matters because social scientists have long known that economic behaviours and social attitudes run in families, but they have lacked the genetic data needed to identify which specific DNA changes might be involved. Most large genetic studies focus on medical traits, not the social and economic measures that shape everyday life—how much people save, whom they trust, or who becomes a leader. By linking genome-wide data to ELSA’s rich social and economic measurements, this project creates a resource that did not previously exist in the UK. If successful, the research could reveal biological pathways that influence financial risk-taking or social trust—insights that might eventually inform how policymakers design pension systems or community programmes. The two demonstration projects will test whether obesity causes poor well-being (or the reverse) and whether genetic markers explain variability in savings behaviour and trust. The core value, however, is the resource itself: a dataset that allows other researchers to ask new questions about the biological underpinnings of social and economic life.

A number of studies suggest that many economic and social outcomes are 'heritable'. However the actual genetic changes associated with these outcomes are yet to be determined. These questions can be addressed by analysis of large population studies which have detailed phenotypic information. However, there are few studies with detailed phenotype measurements of interest to social science and genome wide scan data. ELSA contains cutting edge social and economic phenotype measurements. Additionally, it has a wide variety of biological and health phenotypes and all the measurements have been made at a number of time points. We propose to examine data from approximately 8000 people from the English Longitudinal Study of Ageing and its DNA repository, the EDNAR, with replication in in ELSA's sister study the Health and Retirement study (HRS) which measures many phenotypes. We will create a dataset of genome wide association scan data for the academic community. An important main aim of the project is to provide support for the academic community to use the resource. We will provide high quality genetic data which can be examined alongside the high quality social and economic data that have already been collected in ELSA. A core agenda of this project is develop a new area of research in the UK. We intend to provide training and support to use the repository. In particular, we will organise a workshop inviting participants who play a leadership role in UK social science. The intention is to support the development of skills and capacity within the social science community to enhance the utility of the resource. Further we will perform two projects to demonstrate the utility of the resource. The first will be to examine whether genome wide data explains variability in measures that have economic and social science interest. Data will be conducted in ELSA and in its sister study, the Health and Retirement Study in the United States. Specifically we will focus on risk behaviour (savings behaviour in the context of income); trust (in the context of neighbourhood characteristics) and leadership. These analyses have the potential to impact science in a number of areas. For example, the potential to understand the genetic contribution to variability in social and economic outcomes and the potential to help us understand the biological pathways that underpin these attitudes, behaviours and preferences. The second project will use genetic markers associated with obesity and well-being to examine the their bi-directional association of obesity. These analyses, which are designed to use whole genome information to help to understand whether obesity is causally associated with poor well-being or vice versa, address two areas of great public health significance, namely the obesity epidemic and psychological well-being. Our findings from both demonstration projects will be disseminated to the academic community and the relevant policy organisations through newsletters, conferences, seminars, policy forums and academic papers.
