The increasing gap between developed and developing world will be one of the most important themes of the 21st century. The contributions contained in this volume take a multidisciplinary approach to the problem, offering a comprehensive review of the theoretical issues and empirical findings that relate to the complex and multidirectional link between poverty and demographic behaviours and outcomes in the contemporary developing world. The starting point of the volume is an exact definition of poverty. The contributors go on to analyse in the detail its causes and effects, both at the micro and macro level, concentrating on those factors and consequences which relate more directly to the demographic sphere. Population growth, household structure and labour, fertility, AIDS, urbanization, migration, and mortality are amongst the areas covered, with the major themes discussed and elaborated in an introductory overview chapter.
