The aims of this research are the establishment of the level and the structure of European and national identity of the citizens of Serbia and Montenegro, as well as the establishment of relations between socio-demographic characteristics of the subjects (regional belonging, age, level of education) and European identity. The sample consisted of 2853 subjects from four regions (Vojvodina, Šumadija with Belgrade, Southern Serbia, and Montenegro), divided into two age groups and two levels of education. To evaluate certain components of national and European identity, we applied EUROID2002 scale (Franceško et al., 2002). The application of the cluster analysis method defined three groups of subjects of various social identity profile: 1. multi-layered identity (European and national), 2. national exclusivity and 3. undifferentiated social identity. As factors of differentiation of subjects in the respect of European and national identity, there emerged regional belonging, age and educational level. Besides, the results show that the level of education is the most important factor in the creation of this form of social identity.
