The paper summarizes the concepts, methods, and results of a study on measuring health system inequalities in six countries of the Latin American and Caribbean region: Brazil, Ecuador, Guatemala, Jamaica, Mexico, and Peru. Illness concentration curves and a health status inequality index are used to assess and compare health status inequalities. Concepts of vertical and horizontal equity and inequity and inequality indices are used to measure inequities in access to health care services and in the financing of national health systems. Socioeconomic groups use benefit incidence analysis to assess the distribution of the benefits of government expenditures on health.
