Women make up the vast majority of those married before entering adulthood 47.6 million compared to 5.8 million men.

Girls are disproportionately affected, with 1 in 5 young women aged 20 to 24 years old married before their 18th birthday, compared to 1 in 30 young men.

An estimated 650 million girls and women alive today were married in childhood.

Absolutely no one is saying that boys aren’t victims.

You are delusional to push that child marriage affects boys at the same rate as girls.
