Societal progress is about improvements in the well-being of people and households. Assessing such progress requires looking at the diverse and multidimensional experiences and living conditions of people. Measuring well-being and progress is a key priority that the OECD is pursuing through its Better Life Initiative and the How’s Life report series that has been published bi-annually since 2011. In addition, the UN Sustainable Development Goals (SDGs) have created a strong need for better data on multi-dimensional outcomes. However, no statistical framework exists linking conceptual frameworks of well-being with specific measurement instruments and outputs, and a lack of harmonised data suitable for international comparisons remains a key limitation to monitoring progress across countries. This review makes a first step towards developing a system of well-being statistics. A data source that has been underutilised in assessing the multidimensionality of human well-being and the joint distribution of outcomes are General Social Surveys, which are run by the majority of national statistical agencies as part of their regular survey programme. Using the OECD well-being framework, this review systematically considers the outcome domains of How’s Life?, taking stock of how each domain is being measured through General Social Surveys conducted in OECD countries and could be drawn upon in comparative analyses of well-being such as How’s Life?. The paper highlights inconsistencies between General Social Surveys across countries, and makes recommendations towards harmonization.
