A Study on Illegal Immigration into North-East India: The Case of Nagaland

Migration is a global phenomenon; and it will continue to do so in the near future. All through human history, it has been a significant factor influencing population change. Migration involves the (more or less) permanent movement of individuals or groups across symbolic or political boundaries into new residential areas and communities.1 In ancient times, migration usually took place in small groups, such as tribes or clans, whereas today, it is generally by individuals or families. There are two forms of migration: (a) internal migration (movement of people from one area of a country to another for the purpose or with the aim of establishing a new residence); and (b) international migration (movement, either permanently or temporarily, of people from their country of origin or of habitual residence to another country). International migration can be: (a) emigration (people moving out of the country); and (b) immigration (people coming into the country).
