Map 1. Child and adolescent populations: The child and adolescent populations map focuses on demographic indicators that demonstrate the declining proportion of children and adolescents in the aggregate global population. These indicators are the child-specific pieces of a global demographic shift. The shift is the result of a global decline in birth and death rates with a corresponding increase in life expectancy at birth. As the map demonstrates, the demographic reversal is most visible in northern industrialized countries and is less pronounced in developing countries. While the deceleration has occurred in all regions of the world, it began earlier and has been more pronounced in industrially developed countries. This has exacerbated the existing differences in population and has helped to create the difference in under-19 populations between the more developed and less developed regions.
