Population transfer

Population transfer or resettlement is the movement of a large group of people from one region to another, often a form of forced migration imposed by state policy or international authority and most frequently on the basis of ethnicity or religion but also due to economic development. Banishment or exile is a similar process, but is forcibly applied to individuals and groups.
