It is critical that the wellbeing of society is systematically tracked by indicators that not only give an accurate picture of human life today but also provide a window into the future for all of us. This book presents impactful findings from international longitudinal studies that respond to the United Nations’ Agenda 2030 commitment to “leave no-one behind”. Contributors explore a wide range and complexity of pressing global issues, with emphasis given to excluded and vulnerable populations and gender inequality. Importantly, it sets out actionable strategies for policymakers and practitioners to help strengthen the global Sustainable Development Goals framework, accelerate their implementation and improve the construction of effective public policy.
