Population migration is a complex social process by its nature and diverse in forms and consequences. Migration in its essence is a multidimensional phenomenon, including demographic, ethno-religious, political, economic and other components. Ethno-religious migration processes are primarily ethnosocial and confessional factors leading to transformation in the territorial and social situation of individual representatives and groups of certain ethnic groups and confessions, which occur under the influence of socio-political and other factors. The experience of interethnic relations over the years clearly shows that misunderstandings and conflicts arise more often and manifest themselves more acutely in the multicultural world and polyethnic communities.The article examines the causes and consequences of the migration of Muslims to Europe, the prospects of increasing the number of Muslim population in the countries of the European Union.
