Accessing family planning can reduce a significant proportion of maternal, infant, and childhood deaths. In Ethiopia, use of modern contraceptive methods is low but is increasing. This study aimed to analyze the levels, trends, and determinants of modern contraceptive use and changes over time among young married women in Ethiopia. The study used data from the three Demographic Health Surveys (DHS) conducted in Ethiopia, in 2000, 2005, and 2011. Non-pregnant, young married women age 15-24 were included in the final samples, for sample sizes of 2,157 in 2000, 1,904 in 2005, and 2,146 in 2011.
