The excess infant and child mortality rates among twins calls for a need to identify the main causes behind it. This study intended to identify ri sk factors that are significantly associated with survival of under-five twins in Ethiopia. Data about twin under-five mortality was found from the birth hi story of women who were included in the 2011 Ethiopia Demographic and Health survey. This study, therefore, employed bivariate survival analysis approach using gamma frailty models. The results of the study showed that place of residence, preceding birth interval, birth order, and previous child status were significantly assoc iated with under-five twin mortality.enSurvival Analysis of Under-Five Twins in EthiopiaThesis
