There is a growing sense that the'health gap'between socioeconomic groups is getting worse in many countries. To address this gap, conceptual clarity and empirical evidence are needed along with a greater focus on equity in policy-making. This book is designed to present cutting-edge research and policy analysis to a wide non-specialist readership of students, professionals and policy-makers. It brings together in one volume new perspectives on the conceptual foundations of health equity, empirical evidence on the scale and nature of he inequities in health in twelve countries around the world, and assessments of the associated policy developments and their implications for the future. It aims to help build global capacity to measure, monitor and interpret developments in health equity at a national and international level. The in-depth country analyses draw on epidemiology, demography, economics and other fields to approach health inequalities from several different angles. The topics covered range from adolescent livelihoods in Tanzania to the health burden of indigenous peoples in Mexico, from health equity in Japan to the gender gap in life expectancy in Russia. The book is a unique demonstration of global cooperation in bringing together and giving equal weight to work on health equity carried out in the southern and northern hemispheres.
