Twins are relatively rare events, but several studies confirm that they contribute substantially tornmortality in both neonatal and post-neonatal periods. The excess infant and child mortality ratesrnamong twins calls for a need to identify the main causes behind it. This study intended to identifyrnri sk factors that are significantly associated with survival of under-five twins in Ethiopia. Datarnabout twin under-five mortality was found from the birth hi story of women who were included inrnthe 2011 Ethiopia Demographic and Health survey. This study, therefore, employed bivariaternsurvival analysis approach using gamma frailty models. The results of the study showed thatrnplace of residence, preceding birth interval, birth order, and previous child status werernsignificantly assoc iated with under-five twin mortality.
