The shelter is a basic human need crucial for survival in cases of natural hazards or conflict. It provides security, personal safety, and protection from the weather, and prevents ill health and disease.
Needs for shelter and settlements are increasing. The number of internally displaced people across the globe reached 55 million by the end of 2020, with 40.5 million new displacements, the highest annual figure recorded in a decade.
As of 31 December 2020, worldwide, there were more than double internally displaced people than refugees. Among internally displaced people, 48 million fled conflict and violence, and 7 million from disasters, but these figures could be a significant underestimate of the current situation.
Humanitarian organizations help affected communities through immediate shelter response to a disaster or in anticipation of one. They provide technical support and capacity building, financial assistance (including cash assistance and rental support), and building supplies.
