This book - multi-disciplinary and comparative in design - shows evidence from over 40 countries, along with detailed case studies of Sweden, Iceland, Scotland, and the UK. It covers aspects of well-being that include poverty, good quality jobs, the middle class, wealth, health, children's development and performance in school, and reflects on social justice. Leading international scholars challenge our current understanding of what works and draw policy lessons on how to improve the well-being of single parents and their children.
