The 21st century starts with vast inequalities for children in terms of income, access to food, water, health, education, housing, or employment for their families. Half of the world’s children are below the poverty line of $2 a day and suffer from multiple deprivations and violations to basic human rights. More than 22,000 children die each day, and most of their deaths are preventable. This volume presents some of the critical acknowledged voices to move a necessary agenda forward. It explains multidimensional poverty measurements, describes current trends and presents policies to reduce poverty and inequality.
