ABSTRACT
The process of urbanization in Poland is characterized by a more rapid increase in nonfarm population than in urban population. Transformations of the socio-occupational structure which occurred in Poland after the Second World War were at first concerned chiefly with changes in the social system and later with promoting rapid economic growth. Changes in the system as well as rapid socioeconomic development have caused a considerable increase in the size of the working class. The socio-occupational structure of the population will be characterized using data only for that part of the labor force for whom work is their main source of income. The educational level of industrial, construction, and related workers compares favorably with other socio-occupational groups. The dual-occupational population, working simultaneously in individual farming and outside it, is usually termed "worker-peasant." The growth in the working class was accomplished mostly through assimilation of peasants, and it occurred in tandem with the rapid transformation of the economy.
