Abstract

This article discusses classical and modern theories of migration. The authors describe how ideas about this phenomenon have changed over the past decades and what new methods and approaches have been developed to study it. Particular attention is paid to such theories as the «assimilation model», and «the theory of multiculturalism», «the theory of transnationalism». In addition, the article contains a comparative analysis of the theories and reveals their advantages and disadvantages. Conclusions are drawn that migration remains a hot topic and requires further research.
