Professor Bowen, with many years’ experience of research into the economic and statistical aspects of population and world development, provides a survey of the population of the world, and of how political economists have explained population growth. The author’s survey looks first at the mechanisms of growth – fertility, mortality, and migration – followed by an account of theories of growth from Adam Smith to the present day. Professor Bowen, a former fellow of All Souls College, Oxford, who taught at universities in England, America, Australia and Asia, writes from the point of view of a political economist rather than a demographer, and is of particular value to students of development, development economics and demography within departments of economics, economic history and geography.
