Forced migration (also called deracination — originally a French word meaning uprooting) refers to the coerced movement of a person or persons away from their home or home region. It often connotes violent coercion, and is used interchangeably with the terms "displacement" or forced displacement A specific form of forced migration is population transfer, which is a coherent policy to move unwanted persons, perhaps as an attempt at "ethnic cleansing". Someone who has experienced forced migration is a "forced migrant" or "displaced person". Less formally, such a person may be referred to as a refugee, although that term has a specific narrower legal definition.
