The UN IGME was established in 2004 to harmonize child mortality estimates within the UN system for reporting on progress towards the MDGs, to improve methods for child mortality estimation and to enhance country capacity to produce timely and properly assessed estimates of child mortality. The UN IGME is led
by UNICEF and includes the WHO, the World Bank and the Population Division of the United Nations Department of Economic and Social Affairs as full members.
The UN IGME's Technical Advisory Group, comprising leading academic scholars and independent experts in demography and biostatistics, provides guidance on estimation methods, technical issues and strategies for data analysis and data quality assessment.
The UN IGME updates its child mortality estimates annually after reviewing newly available data and assessing data quality. These estimates are widely used in UNICEF's flagship publications, the UN Secretary-General's MDG report, and publications by other UN agencies, governments and donors.
