"Child marriage has rapidly gained international attention over the last decade with donors increasingly recognising the importance of child marriage and its links to a range of development priorities from economic development and poverty alleviation to health, human rights, and social justice. The body of evidence regarding child marriage prevention and response is now deep and wide, and it clearly shows that effective strategies require not only dedicated efforts to address child marriage, but also crosssectoral cooperation and integration. ... Child marriage disproportionately affects girls more than boys. According to UNICEF, 720 million women alive today were married as children, as compared to 156 million men. Some fifteen million girls are married each year worldwide, and across the developing world, one in three girls is married before the age of 18, and one in nine girls before age 15."
