The paper focuses on intergenerational mobility and explores the role of social origin in ending up in various class locations. Latent class analysis was applied to mapping the class structure based on economic, cultural and social assets. Parental education and occupation are used to examine how social origin operates in accumulating the various forms of capital and in getting into different class positions. Out of the forms of capital, economic resources, high cultural capital and prestige of social contacts depend particularly on social origin; these are the main channels affecting mobility into the best class locations. If coming from low educated worker class background, one may get only into one of the bottom class locations, while members of the top class positions come from families where parents hold tertiary degree and have high occupational status.
