Starting from the definition of sustainable, equitable well-being (BES) and linking it to the United Nations 2030 agenda for sustainable development, the course aims to deepen the knowledge of the twelve areas that make up the BES evaluation system. This will take place both by presenting the indicators proposed by ISTAT for each of the dimensions and through the discussion of the scientific literature produced in this regard. Once these aspects have been clarified, the course will focus on a data analysis technique (principal component analysis) that may prove useful in summarizing the 129 overall indicators that make up the BES system. Finally, some clustering techniques will be presented regarding the analysis at the territorial level. These techniques are handy for identifying groups of territories characterised by similar well-being levels.
