Millennium Development Goal- four (MDG- 4) calls for reducing the under-five mortality rate by two thirds between 1990 and 2015. In 2012 the governments of Ethiopia, India, and the United States, in close collaboration with United Nations International Children's Emergency Fund (UNICEF), convened the child survival call to action forum to mobilize political leadership to end preventable child deaths. This report presents the United Nations Inter-agency Group for child Mortality Estimation's (UNIGME's) latest estimates of under-five, infant and neonatal mortality, and assesses progress towards MDG- 4 at the country, regional, and global levels. This report presents following topics: estimating child mortality; and levels and trends in child mortality, 1990 to 2012.
