The objective of this book is to present a systematic analysis of the American occupational structure, and, thus, of the major foundation of the stratification system in this society. Processes of social mobility from one generation to the next and from career beginnings to occupational destinations are considered to reflect the dynamics of the occupational structure. By analyzing the patterns of these occupational movements, the conditions that affect them, and some of their consequences, one attempts to explain part of the dynamics of the stratification system in the United States.
