This study aims to quantify socioeconomic inequalities—and the factors contributing to these inequalities—in measles vaccine uptake among children aged 12 to 23 months in Ethiopia between 2005 and 2016. Inequalities in measles vaccine uptake were investigated based on data from the Ethiopian Demographic and Health Surveys conducted in 2005, 2011, and 2016. Concentration curves and concentration indices were used to measure the degree of inequality, and decomposition analysis was used to identify factors contributing to these inequalities. The overall level of national measles vaccine uptake in Ethiopia exhibited an increasing trend between 2005 and 2016. As indicated by the concentration index of measles vaccine uptake, however, which was estimated at 0.202 (P <.01) in 2005, 0.226 (P <.01) in 2011, and 0.223 (P <.01) in 2016, measles vaccine uptake became consistently more concentrated among children from more affluent households. The dominance test of the concentration curve further confirmed the persistence of inequalities in measles vaccine uptake over time. Various factors—including maternal educational level, antenatal care use, institutional delivery, and exposure to media—were identified as the most important contributors to the inequalities. Although the national measles vaccine uptake showed improvement between 2005 and 2016, socioeconomic inequalities in the uptake persisted over time. Efforts to improve the national immunization coverage should be accompanied by appropriate measures to address the inequalities. • National measles vaccine uptake has exhibited an increasing trend since its introduction in Ethiopia. • In Ethiopia, significant socioeconomic-related inequalities in measles vaccine uptake have persisted over time between the years 2005 and 2016. • Maternal educational level, antenatal care use, institutional delivery, and exposure to media were the major contributing factors for the observed inequalities. • Any policy measures taken in the country to improve measles vaccine uptake should take equity into account.
