Abstract
To study cross-national inequalities in mortality of adults and of children aged 4 times the rate in countries with low mortality. For child mortality, the worse-off group made slower progress in reducing <5 mortality than the better-off group. Inequalities in child and adult mortality are large, are growing, and are related to several economic, social and health sector variables. Global efforts to deal with this problem require attention to the worse-off countries, geographic concentrations, and adopt a multidimensional approach [corrected] to development.
