Today, more children than ever before are displaced within their own countries. At the end of 2019, an estimated 46 million people were internally displaced by conflict and violence. More than 4 in 10, or 19 million, were to be children. This report presents the scale and scope of the internal displacement of children and their families around the world. In many countries, internally displaced children persistently lack access to basic services. They are vulnerable to abuse, violence and exploitation as social norms break down and protective services are no longer available, and often their education is disrupted by delaying or entirely interrupting their learning.
