In the research of migration, we can encounter the application of multidisciplinary approaches with the use of knowledge from existing theories, which implies the need for statistical reporting. It is not always easy to determine who a migrant is, and studies exploring migration can be dividing up according to many criteria. Contemporary literature contains a whole score of studies dealing with migration, its determinants and impacts on the economy, etc. However, there are very few studies dealing primarily with regional (i.e. internal) migration in comparison to the number of studies analyzing international migration. The goal of this study is to point out problems in reporting migration and to propose a strategy to analyze migration based on multilevel research of migration while making this strategy applicable to internal migration.
