There are approximately 900 million adolescent girls and young women in the world who face significant challenges. Many have low primary school completion rates, high rates of child marriage, health risks from early pregnancy, and high risk of contracting HIV/AIDS. They also face threats of violence, trafficking, and harmful practices. However, investing in girls through education and health interventions has significant social and economic benefits, including increased incomes, lower infant mortality, slower population growth, and greater gender equality. The UN has adopted various frameworks and initiatives to promote and protect the rights of girls and empower the most vulnerable.
