There are currently 2.2 billion children worldwide. According to the United Nations, nearly 30 million children are displaced around the world as a result of armed conflicts.

Girls continue to be held back from education, especially in West and Central Africa. For every 100 boys enrolled in primary school, only 90 girls are admitted. The exclusion is worse in secondary school, where only 76 girls are enrolled for every 100 boys.
