Background: Perinatal mortality is an important indicator of health and the quality of health care.rnCountries or regions are often compared using perinatal mortality rate. The aim of the study is torndetermine the trends and inequality in perinatal mortality and its covariates in Ethiopia by usingrnthe three round of Ethiopian Demographic Health Survey (EDHS) data (2005, 2011 and 2016). rnMethod: EDHS sample designs were stratified, clustered and two-stage probability sampling. Therntrend of perinatal mortality rate was computed using the annual rate of reduction and the 95%rnconfidence interval also used to indicate statistically significant reduction. The inequality inrnperinatal mortality was measured by using both the simple (ratio and difference) and complexrnmeasure of inequality (relative concentration index). The concentration index was decomposedrnusing the â€œdecompâ€ package in R studio. rnResult: The trend of perinatal mortality rate in Ethiopia showed slow rate of reduction with 0.72rnpercent reduction per annuum. Annual rate of reduction for the stillbirth rate was -1.3% whereasrnthe early neonatal mortality was 1.5%. The ratio and difference inequality summary measure forrnthe region showed high disparity across region with highest mortality (Oromiya) and lowestrnmortality (Harari region), difference (D)= -0.0070, 95% CI (-0.0117, -0.0023) and the ratio(R) =rn0.7868 95% CI (0.6619, 0.9354). However, place of residence showed insignificant disparityrn(difference (D)= -0.0118, 95% CI (-0.0276, 0.0041) and ratio (R)= 0.7254, 95% CI (0.4962,rn1.0605)). The results indicated that the concentration index for wealth-based inequality across thernthree survey years were 0.0158926, -0.0117815 and 0.01130234, respectively. While thernconcentration index for the level of maternal education over the three-survey year was (-0.00011,rn-0.0013 and 0.0010), respectively. rnConclusion and Recommendation: Even though trend show some rate of reduction in PNMR,rnthe rate remains high in the country. In all survey years (2005,2011 and 2016) there was wealthrnand level of maternal education-based inequality in perinatal mortality. In order to minimize therninequality in perinatal mortality in Ethiopia effort should be made narrowing the economicrnvariation within population (regions).
