Children's rights continue to be subject of international debates. Moving past these debates can be facilitated with an international measure of children's rights. This article introduces the Children's Rights Index, an international measure of children's rights for over 190 countries. The Children's Rights Index consists of two civil rights, two political rights, two social rights, and two economic rights. This article presents country scores on the Children's Rights Index, then examines whether children's rights vary by region and other differences, such as country wealth. It is hoped that the Children's Rights Index will provide evidence on children's rights important to the work of governments and nongovernmental organizations, as well as scholars and others concerned about children's welfare.
