Tamil Nadu is considered a mobile society because its people have a history of migration and a significant diaspora presence in 17 countries across the world. In spite of high mobility being recurrent in Tamil Nadu, there is a lack of comprehensive studies on this theme. The Tamil Nadu Migration Survey 2015 is the first attempt to study the demographic, social, and economic characteristics of migrants, return migrants, outmigrants, and return outmigrants in the state, remittances received, cost of migration, and the problems they face abroad. TMS 2015 is a broad replication of previously conducted Kerala Migration Surveys.
