This paper compares the World Health Organization (WHO) rankings for seventeen industrialized countries with the perceptions of their citizens. The results show little relationship between WHO rankings and the satisfaction of the citizens who experience these health systems. The health systems of some top WHO performers are rated poorly by their citizens, including the low-income and elderly. The two rated most highly by the public rank at the bottom of the WHO ratings. These findings suggest that both public and expert views should be considered in international rankings.
