Return migration, or remigration in the broad sense of that word, is the migration of people back to their country of citizenship, origin, or ancestry. Research topics include the return migration process, motivations for returning, the experiences returnees encounter, and the impacts of return migration on both the country of departure and the country of arrival. This migration may be voluntary in line with the right of return, or it may be involuntary as a result of deportation.
The exact numbers are debated, but historian Mark Wyman says that return migration has been an enormous phenomenon, and he gives this example: "at least one-third of the 52 million Europeans who left Europe between 1824 and 1924 returned permanently to their homelands."
Return migration is the repatriation of a migrant. It should be distinguished from circular migration, in which migrants repeatedly travel to and from the country of origin, for example to plant and harvest crops each season.
Return migration to the original home by migrants living in their new home can be motivated by numerous factors, singly or in combination. Some common motivations for return migration are:
Return migration can have major impacts on both the migrants themselves and the countries involved. For the migrants, it can lead to cultural readjustment, the reestablishment of social networks, and potential economic opportunities. For the countries of origin, return migration can bring back human capital, skills, and resources that contribute to development and economic growth. However, return migration is not always a smooth process. Migrants may face challenges in reintegrating into their home societies, including finding suitable employment, adapting to changes in the local environment, or dealing with the stigma associated with migration. The decision to return is often influenced by a complex interplay of individual circumstances and broader economic, social, and political factors.
Voluntary return is the return of eligible persons, such as refugees, to their country of origin or citizenship on the basis of freely expressed willingness to such return. Voluntary return, unlike expulsion and deportation, which are actions of sovereign states, is defined as a personal right under specific conditions described in various international instruments, such as the OAU Convention, along with customary international law.
Certain countries offer financial support to refugees and immigrants to help them start a new life in their country of origin. Examples in the 21st century are:
Two countries may have a re-admission agreement, which establishes procedures, on a reciprocal basis, for one state to return "irregular" non-nationals to their country of origin or to a country through which they have transited. Illegal immigrants are frequently repatriated as a matter of government policy. Repatriation measures of voluntary return, with financial assistance, as well as measures of deportation are used in many countries.
Involuntary or forced repatriation is the return of refugees, prisoners of war, or civil detainees to their country of origin under circumstances that leave no other viable alternatives. According to modern international law, prisoners of war, civil detainees, or refugees refusing repatriation, particularly if motivated by fears of political persecution in their own country, should be protected from refoulement and given, if possible, temporary or permanent asylum.
While repatriation necessarily brings an individual to his or her territory of origin or citizenship, a return potentially includes bringing the person back to the point of departure. This could be to a third country, including a country of transit, which is a country the person has traveled through to get to the country of destination. A return could also be within the territorial boundaries of a country, as in the case of returning internally displaced persons and demobilized combatants. Bosnia and Herzegovina illustrates this form of return migration, with substantial numbers of displaced persons returning to their original communities following the armed conflict that concluded in 1995, often across the administrative divisions separating the country's entities. The distinction between repatriation and return, voluntary or involuntary, is not always clear.
