The study of identity, as a complex phenomenon, is a subject of various scientific disciplines. Although each discipline, which has the identity as a subject of research, tries to examine and describe it, however, only an interdisciplinary analysis of identity, as a phenomenon, can get a clearer and more tangible picture, and more precisely map of identity as well. The paper discusses the results of researching in various scientific disciplines and offers an answer to the question how the identity functions and which are its structural elements. Mapping of identity characteristics and understanding the functioning of identity raises the question to what extent is possible manipulation of identities and how consciously it is done in the individual. The work will also treat the current social and economic situations - people migration - and the importance, from the linguistic standpoint, of the issue of migration of identities.
