ABSTRACT
Intergenerational mobility is usually analyzed in terms of socio-occupational differentiation. The basis for determining the magnitude and direction of intergenerational mobility is mobility tables, in which information on the occupations of fathers is contrasted with data on the occupations of their sons. This chapter is concerned with intergenerational changes in both socio-occupational groups and social classes. It describes social positions attained primarily by persons originating in white-collar and blue-collar families. The trend toward intergenerational stability for sons of blue-collar workers in the heavily industrialized cities of Lodz and Szczecin does not hold for Koszalin. In Koszalin the main mobility path for blue-collar workers' sons is movement to white-collar jobs. In Lodz and Szczecin, on the other hand, the sons of farmers exhibit a propensity to become blue-collar workers. The openness coefficient allows one to measure the intensity of relative exchange mobility. The openness coefficient has been used in the study of mobility in other countries.
