Refugee is a displaced person who has been forced to cross national boundaries and who cannot return home safely. A refugee is someone who has been forced to flee his or her country because of persecution, war, or violence. War and ethnic, tribal and religious violence are leading causes of refugees fleeing their countries. More than half of all refugees worldwide come from just three countries: Syria, Afghanistan and South Sudan. People forced to flee their homes but never cross an international border. These individuals are known as Internally Displaced Persons.
