This paper provides a theoretical framework for estimating the labor migration impact on the economy of sending country. The overall emigration impact includes two effects, which can be calculated separately, i.e., a departure effect and a remittances effect. The departure effect causes a negative impact on the economy by decreasing autonomous consumption. The remittances effect causes a positive impact by increasing disposable income and thus internal consumption and savings and imports. Calculations include the multiplier effect. The labor emigration impact on GDP is calculated as a difference between a positive remittances effect and a negative departure effect. The analysis is conducted for countries that are not at full employment.

The paper assumes that deportation is one of the kinds of migration, particularly forced migration, e.g. refugees. The necessity of research arises as millions of people were affected by deportation last century and much more previously. Even nowadays, deportation still occurs. Nevertheless, it has little attention from publicity, specifically from political and scientific communities. Therefore, the paper aims to provide theoretical justification and reveal historical evidence to describe this practice, its purpose and scale, and its impact on deportees. We pursue that deportation has to receive more attention, especially from international organisations like the UN and IOM. Special bodies within this organisation have to be created to help victims of deportation, similar to refugees. The paper starts with building up the theoretical justification by analysis of definitions of "deportation" provided by other authors, its characteristics and peculiarities. Further, we continue with the comparison of deportation and other types of forced migration. Finally, we provide a definition of deportation. The second part of the paper reveals historical evidence of deportation from ancient history to modern times, including nowadays.
