This chapter attempts to integrate the objective, cognitive and normative dimensions of mobility in a unified framework by analyzing the relations between them. The material dimension characterizes "what objectively exists": reality is described by means of frequencies of transitions among all origin and destination categories. It assumes that rough estimates of the frequencies of mobility transitions are implied in people's images of the mobility process and, as such, are retrievable for assessment of "what is believed to be". Equitable mobility is defined as the complete set of frequencies of mobility transitions that are inferred from people's judgements about the just distribution of destinations among persons originating in each of the major segments of society. The chapter compares perceived mobility to actual mobility and account for distortions in perception independently of class-related causes. It discusses mobility patterns among the three major social classes in Poland: white-collar workers, blue-collar workers, and farmers.
