How’s Life? is part of the OECD Better Life Initiative, which aims to promote “Better Policies for Better Lives”, in line with the OECD’s overarching mission. It is a statistical report released every two years that documents a wide range of well-being outcomes, and how they vary over time, between population groups, and across countries. This assessment is based on a multi-dimensional framework covering 11 dimensions of current well-being, and four different types of resources that help to support well-being over time. Each issue also includes special chapters that provide an in‐depth look at specific aspects of well-being. The 2017 edition features a focus on inequalities in well-being, migrants’ experiences of well-being, and the role of governance in well-being.

The report was prepared by the Household Statistics and Progress Measurement Division of the OECD Statistics Directorate, with contributions from the Reform of the Public Sector Division in the Public Governance Directorate (Chapter 4). Lead authors for each of the chapters were: Carrie Exton (Chapter 1); Carlotta Balestra (Chapter 2); Kate Scrivens and David Marguerit (Chapter 3); Santiago Gonzalez (Chapter 4); and Joshua Monje-Jelfs and Elena Tosetto (Chapter 5). Elena Tosetto was also the lead author for both online annexes. Carrie Exton led the project, which was supervised by Romina Boarini, Marco Mira d’Ercole, and Martine Durand. Lara Fleischer and Giampaolo Bonomi are gratefully acknowledged for their contributions to the analyses that appear in the report and in the media notes. Martine Zaïda is the communications coordinator for How’s Life?, and has provided essential support throughout.
