At the height of nationwide lockdowns due to the COVID-19 pandemic, up to 1.6 billion children were affected by school closures, causing the largest mass disruption of education in modern history. This joint report by UNICEF and the International Telecommunication Union (ITU) presents new insights into children and young people's access to digital connectivity worldwide, as well as the factors that drive inequities among and within countries. As a result of this learning crisis, UNICEF has joined forces with ITU to launch Giga, an ambitious global initiative to connect every school to the internet and every young person to information, opportunity and choice. With the support of Generation Unlimited, UNICEF now works under the Reimagine Education initiative to transform education by giving children and young people equal access to quality digital learning.
