This book profiles the lives of the poor workers and vagrants of London. Most of the book deals with the characteristics of groups of people by occupation, rather than in-depth profiles of any one person. This technique, of using a little evidence to arrive at sweeping generalizations and draw broad conclusions, was much more common in Mayhew's time than it is today. Where a journalist of today would present a compelling word portrait of a specific individual to illustrate the problem, Mayhew relied on generalities. For this reason, there are few specific individuals to reference. Even when a brief profile of a specific individual is given, he or she is unnamed.
