Child mortality is a factor that is strongly associated with the well-being of a populationrnand it is taken as an indicator of health development and socioeconomic status. Childrnmortality rates are falling, but not quickly enough. According to the 2011 UN reportrnduring the last 10 years, the death rate for children under five has decreased by 35%rnworldwide. UNICEF in 2008 reported that Ethiopia has reduced under-five mortality byrn40 percent over the past 15 years. From the EDHS 2011 report child mortality rate inrnEthiopia was reduced from 50/1000 deaths in 2005 to 31/1000 deaths in 2011. ThernEthiopian Demographic and Health Survey data are used for the study. The study usesrninformation on 12,710 children included in the survey for the entire country. The mainrnobjective of the study was to identify determinants of under-five child mortality. For thisrnpurpose survival analysis was employed. The results show that mother’s education,rnmother’s age, marital status, birth order and place of residence are the significant factorsrnthat contribute to under-five child mortality. However, sex of a child, family size, wealthrnindex, water source and toilet facility are not found to be significant. In order to reducernthe rate of under-five child mortality attention should be paid to improve mother’srneducation and discourage early marriage.
