COVID-19 school closures disrupt education for ~1.6 billion learners (2020)
At the April 2020 peak of the COVID-19 pandemic, school and university closures affected over 1.6 billion learners (about 94% of the world's student population) in more than 190 countries; on average roughly two-thirds of an academic year was lost worldwide, and more than 400 million learners could not access any distance learning.

The closures forced a rapid global scale-up of remote/online learning, sharply raising the salience and intensity of the digital-learning-access driver (while exposing deep access gaps).
