This report presents a compilation of statistics disaggregated by gender concerning the main childhood and adolescence stages in the developing world. It examines a selection of indicators currently available to measure the well-being and assess the rights of children from early childhood to young adulthood (breast-feeding, nutrition, care, forced marriage and sexual relations, education, level of information on HIV/AIDS...). By offering an assessment that takes gender differences into account, the objective is to help shed light on future policies and programmes.
