How’s Life? describes the essential ingredients that shape people’s well-being in OECD and partner countries. It includes a wide variety of statistics, capturing both material well-being (such as income, jobs and housing) and the broader quality of people’s lives (such as their health, education, work-life balance, environment, social connections, civic engagement, subjective well-being and safety). The report documents the latest evidence on well-being, as well as changes over time, and the distribution of well-being outcomes among different groups of the population. This third edition of How’s Life? develops understanding of well-being in new ways. There is a special focus on child well-being, which finds that not all children are getting a good start in life, and those living in less affluent families face more risks to their well-being. The report introduces new measures to capture some of the natural, human, social and economic resources that play a role in supporting well-being over time. A chapter on volunteering suggests that volunteer work can create a virtuous circle: doing good makes people feel good, and brings a variety of other well-being benefits to both volunteers and to society at large. Finally, the report looks at inequalities in well-being across different regions within countries, demonstrating that where people live can shape their opportunities for living well.
