All over the world, populations with fewer resources have worse life chances, health, and well-being. The unequal distribution of resources and their consequences in well-being is a current discussion, with growing importance (UN, 2015, OECD, 2015, Stiglitz et al, 2018a and 2018b), as well as the search for informative and analytical elements for greater reflexivity and social intervention capacity (Mauritti et al., 2016, Botelho et al., 2018, Wilkinson and Pickett, 2018). In Europe and particularly in Portugal, where there are great disparities, the construction and improvement of tools for analysing the relationship between social inequalities and well-being is essential. This presentation is part of an ongoing research project on the relationship between welfare and social inequalities in Europe that have two main objectives: (i) to present dimensions and indicators of well-being perceptions; (ii) and discuss different quantitative methodologies for the construction of a global and integrated well-being index. The well-being approach is based on the multidimensional concept developed by the OECD through the Better Life Initiative (OECD 2013, 2015, 2017). This model is starting to have an impact on how states and reference entities assess the progress of societies. This guidance also includes the work of EUROSTAT (Eurostat, 2017) or other more recent approaches, focusing on the perspective of justice and social progress (Stiglitz et al, 2018a and 2018b). Our quantitative methods support an innovative research line because it analyses the microdata of the European Social Survey (the year 2016), aiming to portray the global perceptions of the well-being of the Europeans.
