What's the difference between "refugee" and "exodus"?
A “refugee” is any person fleeing their home (or country) due to reasons of war, religion, politics, the economy, or any other forms of persecution. An “exodus” is not a person but a mass departure or migration, which can include people. Thus, refugees may be part of an exodus, but an exodus is not always caused by refugees. Ex: The number of refugees displaced by environmental change is growing. Ex: Every year, there is a mass exodus of retirees to sunny vacation spots in the South.
