"The analysis of the determinants of well-being has typically been carried out either at the micro-level to quantify the relationship between income and well-being of individuals within countries, or at the macro-level looking at the aggregate relationship between happiness and GDP between countries. In this project we consider a multilevel structure where characteristics both at the individual and aggregated levels jointly determine life-satisfaction. Our focus is the economic and non-economic determinants of well-being across Europe and we ask what level of geographical aggregation (e.g. individual, regional or national) matters for individual well-being and whether the drivers of well-being differ across these multiple levels, i.e. within and between countries. In particular, we wish to understand how the degree of interaction by individuals within a group, at broadening levels of society, can affect their well-being. We therefore allow individuals to be related to others in their immediate `vicinity' or neighborhood, and then explore how these smaller groups themselves are related to larger clusters of individuals at the neighborhood and regional level. The availability and use of the 2006 and 2008 European Social Survey data means that we can gauge well-being across both Western Europe, the original EU member states and the new accession countries."
