Child Nutrition and Water Access

World population has reached a transition point: The rapid growth of the second half of the 20th century has slowed. But factors such as continuously improving mortality and slower than expected declines in birth rates guarantee continued growth. There are large differences between the age structure of populations in developed and developing countries and the demands they place on societies. Youth dependency is relatively low in developed countries and significantly greater in developing countries. Improved health and living standards increased access to education and economic growth have led to lower fertility rates and longer life expectancy in every region and across socioeconomic groups. While this shift represents a major global success story aging populations also present challenges. Women are essential to the demographic dividend—the potential of a large cohort of youth to provide a boost to economic growth. But in a majority of countries women are more likely to be unemployed than men. An estimated 1.5 million deaths are caused by diarrhea each year largely due to lack of clean drinking water poor sanitation and hygiene and poor nutrition and health status. Improving sanitation reduces diarrhea deaths. The most recent data indicate that progress in meeting the Millennium Development Goal target on sanitation is insufficient.
