Population growth is a prominent issue in rural Ethiopia where about 85rnpercent of the population resides. Therefore, simply put, the determinants of therneffects of the various factors on fertility rates in rural Ethiopia is a relevant policyrnoriented research. This paper looked at s~d proximate determinants and socioeconomicrnfactors and their effects on fertility in a rural setting. The study collected information on 2063 women in Mafud and Kewetrndistricts, and used various techniques including oneway analysis, multiplernclassification analysis and the Bongaarts model to look at the relative effects of thernselected variables. The findings include that land-holding, literacy program,rnlivestock value, marital disruptions, infant- child mortality and spontaneousrnmiscarriages had positive effect on fertility. On the other hand, formal education,rncontraceptive use, breast-feeding and age at first marriage showed negative effectsrnon fertility in the studied rural areas of Ethiopia. The results also indicated thatrnamong the rural areas studied, fertility levels varied by the rate of infant-childrnmortality, the levels of infecundity and contraceptive prevalence.rnIn conclusion this study identified areas of policy concentration in relationrnto reducing fertility levels as well as areas of future research to better understandrnthe dynamics of fertility behavior in rural Ethiopia.
