Each year, childhood ends for an estimated 15 million girls around the world who marry before the age of 18, according to the International Centre for Research on Women (ICRW). South Asia has the largest concentration of child brides, but early marriage is a global phenomenon.

Child brides commonly face domestic violence, restricted movement and are often not given a voice when it comes to making decisions in the family. No matter the justifications families give, the ICRW says, child marriage is 'a violation of human rights and a form of violence against girls'. 'I wanted to be a doctor' Fatima f
