tion:Human migration is the movement of PEOPLE from one place to another with the intentions of settling, permanently or temporarily, at a new location (geographic region). The movement is often over long distances and from one country to another, but internal migration is also possible; indeed, this is the dominant form globally. People may migrate as individuals, in family units or in large groups. There are four major forms of migration: invasion, conquest, colonization and immigration.A person who moves from their home DUE to forced displacement (such as a natural disaster or civil disturbance) may be described as a displaced person or, if remaining in the home country, an internally displaced person. A person who is seeking refuge in another country can, if the reason for leaving the home country is political, RELIGIOUS, or another form of persecution, make a formal application to that country where refuge is sought and is then usually described as an asylum seeker. If this application is successful this person's legal status becomes that of a refugee.In contemporary times, migration governance has been closely associated with State sovereignty. States retain the POWER of deciding on the entry and STAY of non-nationals because migration directly affects some of the defining elements of a State.
