ABSTRACT Background: The launch of the Millennium Development Goal4, in 2000 and the national and international mobilization it spurs results to a decline of child under age five mortality rate from 90 per 1000 living birth in 1990 to 40 per thousands in 2012. That decline however is not evenly distributed across the globe and the majority of countries in the Sub-Saharan African region continue to experience a higher rate of under age five mortality than expected in 2013. Within country disparities in child mortality and it determinants was suggested to account for the lagging of those countries to reduce their under age five mortality rate. Objective: the study examined the variation in child mortality across statistical regions in Cote d’Ivoire and the community level factors that can explain those variations after controlling child, the mothers and the household characteristics. Method: The study used data obtained from the 2011-2012 Cote d’Ivoire’ Demography Health Survey. The study population consisted of 7511 children born within the 5 years preceding the survey. Frequency tables were created to show the distribution of the selected child mortality determinants across regions in Cote d’ivoire and three Logistic models were run to measure the association between the under age five mortality and the selected determinants. Results: The proportion of under age five mortality in the study population was 8.52%. There was a statistically significant variation in child mortality across regions. At the community level, the proportion of mothers with a least a secondary education was associated with under-age five mortality risk (OR=0.99, CI=0.98-0.99). There was no significant association between child mortality and the other selected community factors included in the study. Conclusion: This study reveals a significant variation of under age five mortality rate across region in Cote d’Ivoire, even after controlling or child, mother and household level factors. The findings of this study suggest a need for further exploration of the factors that can explain those differences.
