Existing evidences show an inverse relationship between income and fertility among countries,rnand across households. Although the inverse association is observed quite often, there arernconditions under which fertility and income are correlated positively. Many studies find lowerrnfertility among those who earn high income. Nonetheless, it is sometimes argued that early on inrnthe development process, a positive relationship between income and fertility could exist. Mostrnof the studies that document a positive relationship are subsumed in agrarian economies, andrnoften income is peroxide by farm size. This paper explored the relationship between householdrnincome and fertility, in cross sectional manner using primary data in Wereda 4 and 10 located inrnAddis Ketema Sub-City of the City Government of Addis Ababa. The study used Poissonrnregression model and descriptive statistics. Poisson regression model accounts for the nonnegative count variable. A cross-sectional based study was held on 422 randomly selectedrnreproductive age women using primary data which was collected using structured questionnairernthrough face to face interview. The bivariate findings of the study indicated that the meanrnchildren ever borne was 1.92 which below the replacement level. On the other hand, to assessrnthe effect of household income on children ever borne, the Poisson regression model was fittedrnand significant determinant of children ever born he multiple Poisson regression result showsrnthat Household Yearly income was significant predictor on the mean children ever borne (b= -rn0.019 S.E=0.005 Sig =.027 with weld confidence interval 95%) and the incidence rate ratiorn(found in EX (B) column) is 0.935 which indicates that household income was negative andrnsignificant determinant for the incident rate of children ever borne . Furthermore, marital status,rneducational level, age group, age at first marriage and occupation are significant determinant ofrnchildren ever borne, while religion is not significant determinant.
