Estimating Subfecundity: The NLSY79 Cohort Presented: Washington DC, Population Association of America Annual Meeting, March-April 2016 Cohort(s): NLSY79 Publisher: Population Association of America Keyword(s): Contraception; Expectations/Intentions; Fertility; Pregnancy and Pregnancy Outcomes Permission to reprint the abstract has not been received from the publisher. Estimating subfecundity in longitudinal social surveys allows for improved understanding of the underlying processes that lead to childlessness and low fertility in contemporary societies. However, most of these surveys lack measures needed to directly estimate impaired fertility. This paper provides indirect estimates of subfecundity in a longitudinal cohort of women by using observed pregnancy and partnership histories, as well as reported contraceptive use and expectations for children over the life course. Data are from the National Longitudinal Survey of Youth 1979 cohort, whose members have recently completed childbearing. I use a multi-state model to estimate transition probabilities between states of exposure to the risk subfecundity, identify spells of subfecundity, and duration of time spent in a spell. Future analyses will investigate the sensitivity of the measure to different specifications of risk, as well as the demographic, behavioral, and socioeconomic correlates of experiences of subfecundity in this cohort. |
