"The State of the World's Children 2017" examines the ways in which digital technology has already changed children's lives and life chances -- and explores what the future may hold. If leveraged in the right way and made universally accessible, digital technology can be a game changer for children being left behind -- whether because of poverty, race, ethnicity, gender, disability, displacement or geographic isolation -- connecting them to a world of opportunity and providing them with the skills they need to succeed in a digital world. But unless we expand access, digital technology may create new divides that prevent children from fulfilling their potential. And if we don't act now to keep pace with rapid change, online risks may make vulnerable children more susceptible to exploitation, abuse and even trafficking -- as well as more subtle threats to their well-being. This report argues for faster action, focused investment and greater cooperation to protect children from the harms of a more connected world -- while harnessing the opportunities of the digital age to benefit every child.
