Introduction: Despite increase in trend of contraceptive utilization in worldwide it was still low in developing country. In Ethiopia modern contraceptive utilization among young married women was low which shows gaps between women reproductive desire to avoid pregnancy and contraceptive behavior. This study shows varation in modern contraceptive utilization and factor associated with it among young merried age group between 15-24 years in Ethiopia. Objective: The aim of the study was to assess the geographical varation of modern contraceptive utilization and associated factor among young married women aged between 15- 24 year in Ethiopia. Methods: Cross-sectional study design was applied using Ethiopia demographic and health survey 2016 data. The sample size was 2298 young married women aged between 15-24 years. Spatial analysis was done using spatial autocorrelation Moran’s I, Gettis-OrdGi* and spatial scan statics to identify significant clusters of modern contraceptive utilization. The data were analyzed using a two level-mixed-effects logistic regression model to determine the individual and community level factors associated with modern contraceptive utilization.Result: In Ethiopia, prevalence of modern contraceptive utilization among young married women age group 15-24 years was 36.7 %. Spatial scan statistics identified primary clusters of modern contraceptive utilization were all zone of Amhara, Addis Ababa and Shewa. In other hand, Gettis-OrdGi* analysis indicated zone 1 of Afar region, Borena zone of Oromia region and all zone of Somalia regions were low prevalence spot region. In this study religion, wealth index, religious, health facility visits within 12 months, husband desire more children, perception of distance from health facility, region, Community access to health services and community educational level were statically significant variables for modern contraceptive utilization.Conclusions: There is low prevalence of modern contraceptive utilization and it was varied across zone of Ethiopia. High and low prevalence spot area, most likely cluster, community and individual level factor associated with modern contraceptive utilization is identified which is important to prioritize family planning strategy. Therefore, exerting much effort on this area is supreme important as it has significant public health contributions.
