Abstract: In this study, I examine the risk of first contraception among Ethiopian women. I use the 2005 Ethiopian Demographic and Health Survey and apply Continuous-Time Event-History Analysis to follow women from age ten to the time of first use or at the interview, whichever comes first.   The multivariate analyses by controlling all variables show that risks for first contraception are higher at higher parities, at younger and older ages, for Orthodox religion followers, the Tigrie ethnic group, women who completed primary education, in the Benishangul-Gumuz and Gambela regions and in urban areas and for younger cohorts.
