This paper gives a comparative overview of inter-generational mobility in 7 countries of Central and Eastern Europe, including Serbia, at an early stage of postsocialist transformation. The analysis was based upon surveys organized in these countries in 1993. Basic findings show that a great social and economic transformation does not lead to a great structural mobility. The processes of formation and reproduction of the strata of political and economic managers and small entrepreneurs to some extent make an exception in this sense. These processes are marked by higher openness as compared to other strata. In such a comparative framework Serbia appears to be structurally the most closed one, more closed even than other countries that could be classified as countries with a blocked transformation (Bulgaria and Russia). Very high self-reproduction of managerial and middle strata make an essence of the low mobility of the Serbian society.
