A refugee was an individual who has been displaced from their home due to conflict or violence, and who sought shelter or a new home.
Ace once saw someone on television say that nobody likes a refugee, since the people whom the refugees are trying to get away from don't like them and the people whom the refugees go to for shelter don't want them. (PROSE: Cat's Cradle: Witch Mark)
In the century leading to their invasion of Earth in 200,100, the Daleks led by the Dalek Emperor harvested the refugees and dispossessed, who they referred to as the "waste of humanity", to create a new army of human-derived Daleks. (TV: The Parting of the Ways)
