Early marriage involves one or both spouses being children and may take place under civil, religious or customary laws. According to the 1948 Universal Declaration of Human Rights, marriage should only be entered with the free and full consent of the intending spouses. Child marriage is still practiced in some parts of the world despite international agreements prohibiting it. While early marriage can negatively impact girls' health, education and empowerment, poverty and lack of opportunities also contribute to the practice. A multifaceted response is needed to address this complex issue.
