So the first task of this preface is to establish that while those listed on the title page collaborated on estimates of social mobility rates in various societies, the text itself was written by me. The interpretation of the evidence from these studies, and the proposed theory of mobility presented in the book, all represent my opinion alone. Also, none of the people I thank below should be taken as endorsing the conclusions of the book. My second task is to note that the spirit and style of this book follow those of my earlier book, A Farewell to Alms: A Brief Economic History of the World. It tries to show that extraordinarily simple models of social mobility can successfully predict outcomes across a whole range of societies and institutions. This is a claim based on incomplete evidence. It may be wrong. But even if it is wrong in aspects, I hope it will point the way to a better and more complete theory of the mechanisms of social mobility. Even in an area as freighted with aspirations and disappointments as social mobility, there should still be room for exploration and conjecture. The work discussed in this volume was undertaken with several collaborators. The most extensive collaboration was with Neil Cummins, who is jointly responsible for most of the material in chapters 4 and 5 on England. The chapter on China and Taiwan reports on the work Yu Hao completed for his graduate dissertation here at the University of California, Davis, where he devised the methods needed to deal with the small numbers of Han Chinese surnames. The chapter on Chile is a
