The International Labor Organization is responsible for monitoring labor conditions and promoting social justice along with human and labor rights. This portion of the site is devoted to providing compendiums of statistics pertaining to child labor. This data would allow a researcher to follow trends in unfair labor practices, such as slavery, that affect children around the world. The site includes a section that provides guidance for understanding and interpreting the statistics provided.

Executive Director of the United Nations Children’s Fund Carol Bellamy compiles and unpacks statistics on conditions for children around the world. This is applicable for research on slavery because, as Bellamy writes, “according to the International Labour Organization, every year an estimated 1.2 million children are trafficked into forced labour or prostitution.” Bellamy makes the argument that girls are particularly vulnerable, and that one of the best ways to improve conditions for girls is through education. This article is rich in statistics about the educational systems in third world countries and how they rank in educating girls. Page 51 contains statistics pertaining directly to percentages of children in Africa who are in slavery or slave-like conditions.
