BACKGROUND NOTE ON METHODOLOGY FOR UNDER-FIVE MORTALITY ESTIMATION Background and Inter-Agency work Global estimates on under-five mortality are produced on a yearly basis by the Inter-agency Group for Child Mortality

Global estimates on under-five mortality are produced on a yearly basis by the Inter-agency Group for Child Mortality Estimation, which includes UNICEF, WHO, The World Bank, UN Population Division, Harvard University and others. The Interagency group was created in 2004 to share data and ensure consistency among the estimates previously produced separately by UNICEF, WHO and The World Bank. Since then the group has branched out to address common concerns in improving child mortality estimation. Membership has also expanded to include the UN Population Division and experts from universities and research institutes, followed by the US Bureau of the Census, ECLAC and the Demographic and Health Surveys group.
