The opposite of the social mobility concept is the concept of class reproduction. While social mobility registers intergenerational, cohort or career changes in class structure of society, reproductional concept marks the permanence of class disparities from one generation to the other, or in the borders of one generation. The meaning of this expression is not a change but social order. The questions about the reasons of social mobility ask what the cause of change of social position is. The questions about the reasons of society reproduction ask what is the cause of persistence of social position from one generation to the other, between cohorts or in the borders of employees' careers. When we answer the questions about the causes of social mobility, we also answer the questions about reproduction of class position and vice versa. The project is aimed at the analysis of social and cultural reproduction from one generation to the other. The main questions, which the project will answer, are: How does the class structure intergenerationally reproduce? What is the role of the family and family organization in the intergenerational reproduction of the class structure? And what is the role of school and the external social environment? How do the mobility chances change from one generation to the other in relation to school environment? The data that will be analyzed come from the research „Social and Cultural Reproduction 2005“. Also data from the longitudinal research „(Un)equal chances for everyone“ will be used for the analysis.
