This paper investigates socio-cultural differences among European countries. The theoretical roots of our defined socio-cultural dimensions are elaborated in a multidisciplinary field. According to the considerable scientific literature, various sociocultural aspects such as trust, tolerance, civic norms and social networks have a serious impact on the development potential of a country or a region. We empirically tested the characteristics of these socio-cultural aspects on the European Social Survey database. The main conclusion of the paper is that there is a definite socio-cultural cleavage between the northern/western and the Central and Eastern European countries.
