摘要：This research examines the relationship between social and biological characteristics of the infant and mother and the probability of infant survival through the first year of life. The research also includes a consideration of the influence of residence (rural vs. urban). Employing linked birth and death certificate data for Arkansas (1985-1989), a logit model was estimated to assess the impact of social and biological factors on the probability of survival. The results indicate that metropolitan residence is positively associated with infant survival, but only at a marginal significance level. Other notable results include the importance of prenatal care and a lack of significance of race when other factors are controlled
