Refugee

A refugee was an individual who has been displaced from his or her home and who has sought shelter or a new home.

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 refered to as the "waste of humanity", to create a new army of human-derived Daleks. (TV: The Parting of the Ways)
