Studies in Class Structure [PDF ebook] 

First published in 1955, Studies in Class Structure contains six studies in problems of social structure, relating mainly to contemporary British society. Professor Cole studies an analysis of the information about class structure contained in the British Census of 1951; and he also deals with the changes in British class structure during the past hundred years. He considers the structure of elites in contemporary Britain, with some account of their development. He is also concerned with the influence of technical changes on class structures in Europe. These studies do not pretend to embody a comprehensive treatment of the problems of social structure: each of them stands by itself as a sharply original treatment of the many facets of class structure. This book will be of interest to students of economics, sociology and history.
