Abstract
Most explanations of migration to European Union destinations are generally classified in the neoclassical theory of migration, which considers migration as a result of income differences between origin and destination countries. It emerged, however, another theory that explains changes occurring on migration flows: as a consequence of globalization, increasingly extended. In this paper, the authors have applied the Principal Component Analysis in order to identify the main components that influence and explain changes in the migration flows. These components are used as ranking criteria for European countries and they are included in a correlation analysis with indicators of migration flows.
