What is child marriage and why does it happen?
Child marriage refers to all marriages or unions in which one or both spouses are under the age of 18 and or were not able to give their free and informed co…
Through the #EndChildMarriage campaign, we’re standing with girls to dismantle the harmful norms that force them into child marriages and deny them their childhood.
The world is failing girls. Globally,12 million are married before their 18th birthday every year. That’s 1 every 3 seconds. Child marriage steals girls’ childhoods and shuts down their futures.
Without accelerated action, 150 million more girls could be married by 2030.
In many communities, child marriage is still seen as normal, even necessary. But girls aren’t backing down. They’re raising their voices and leading change.
Led by girls, #EndChildMarriage is about action to amplify their voices and build a world where equality for girls leads to progress for all.
This 16 Days of Activism, we’re standing with girls and supporting activism to end child marriage and unions.
This year’s 16 Days focuses on ending digital violence against all women and girls. Did you know that increasing digital relationships create new vulnerabilities for girls? Child marriage is no longer just a traditional practice rooted in family arrangements. Girls have told us that increasingly, it begins online.
Social media enables relationships outside of parental control, and many girls describe marrying for love. But this sense of agency is fragile, as parents may pressure daughters to marry to protect their reputation or family honour.
Meeting online does not reduce risk of violence – in fact it can open the door to manipulation and coercion. Girls may feel empowered, believing they are choosing marriages based on love but older men may exploit emotional and economic vulnerabilities.
Social media can be used in creative ways by young activists to help #EndChildMarriage.

“I was married off young. I wasn’t allowed to study or progress in life — I was deprived of everything. But I won’t let that happen to my daughter.”

Despite the challenges, these girls are determined to protect their own children from the same fate. Not a single girl we spoke to said she would want her child to marry before the age of 18.
