Twenty-five years since the United Nations ratified its Convention on the Rights of the Child, have the lives of the world’s children improved? A new report tried to answer that question and found some gains among ongoing and long-standing challenges.

Examining the quality of life for children in 190 countries, the report card by the University of California’s World Policy Analysis Center found that while child mortality has been halved and more children are graduating from school since the convention was signed in 1989, major issues remain, including child labor, child marriage and discrimination against children with disabilities.
