Displacement happens when people are forced to leave their homes. It can be caused by events such as war, natural disasters, or large building projects like dams. People may move quickly and without preparation.
Some displaced people stay within their own country and are called internally displaced persons (IDPs). Others cross borders and become refugees. Camps or temporary shelters are often set up to house displaced populations.
Displacement is tracked by organizations such as the United Nations using data and reports. It is studied in geography and social science to understand human movement during crises.
