The Impact of Social Status, Family Structure, and Neighborhood on the Fertility of Black Adolescents

Abstract

Black teenagers living in metropolitan areas of the United States initiate sexual intercourse at earlier ages than other teenagers and have higher rates of premarital pregnancy. Ethnographic studies of black families have claimed that economic uncertainties cause young blacks to delay marriage, while many young women achieve adulthood through premarital parenthood. It is also probable that girls who grow up in a female-headed family or who see their sisters become teenage parents are more likely to accept single-parenthood as a way to achieve adult status. These studies have suggested that ghetto neighborhoods are characterized by loosely defined and enforced norms of sexual behavior and age and sex compositions conducive to juvenile deviance. These features of ghetto life make it difficult for parents to regulate successfully their children's behaviors. As a consequence, residents of ghetto neighborhoods are expected to initiate sexual intercourse at earlier ages and to have higher rates of accidental premarital pregnancy than other teens. These hypotheses have received limited support in previous demographic research on teenage fertility. In this paper, these ethnographic explanations of the fertility behaviors of black adolescents are tested, using data from a random sample of more than 1,000 black females aged 13-19 who lived in the city of Chicago in 1979. This analysis improves on previous demographic research by both measuring the total effects of these varibles on fertility and decomposing them into components due to effects on rates of initial sexual intercourse and the probability of conception among the sexually active. A nonbiasing, continuous-time semi-Markov model is used to identify the net effects of these factors on rates of initial sexual intercourse and pregnancy.
