This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. This book discusses recognition of a growing and diverse range of scholars brought together through the British Sociological Association's (BSA) Bourdieu Study Group. It explores individual researchers' application of elements of Bourdieu's theoretical framework and concepts to diverse empirical studies. The book draws on the results from the BBC Great British Class Survey (GBCS) as well as qualitative interviews to illustrate intra-occupational disadvantage and how those from working-class backgrounds experience a class ceiling despite relative social mobility. It shows how Bourdieu's concepts are put into practice in diverse studies, yet each of these studies complements the others. The book analyzes the difficulty of reading original Bourdieusian texts, particularly for students. It examines the practical and theoretical limitations within Bourdieusian social theory and demonstrates ways forward through revisiting concepts and applying them in a different formation.
