Levels and trends in child mortality, 1990-2009.

The authors discuss the latest estimates of under-5 child mortality from the United Nations (UN) Inter-agency Group for Child Mortality Estimation (IGME) reflecting a progress on child mortality. They present a background of IGME, which is led by the World Health Organization (WHO) and the UN International Children's Emergency Fund (UNICEF). They examine the common feature of countries that have made the most significant progress on child mortality. The authors also mention the impact of inequalities on over all progress on child mortality.
