Note: Estimates are based on a subset of 102 countries covering 74% of the  urban under-five population and 94% of the rural under-five population in the developing world (excluding China, for which comparable data are not available in UNICEF global databases). Regional estimates represent data from countries  covering at least 50% of the regional population. Data coverage was insufficient to calculate regional estimates for the Latin America and Caribbean region and Industrialized countries.
