Book Description

This paper presents estimates of delayed childbearing and permanent childlessness in the United States and the determinants of those phenomena.The estimates are derived by fitting the Coale-McNeil marriage model to survey data on age at first birth and by letting the parameters of the model depend on covariates. Substantively, the results provide evidence that the low first birth fertility rates experienced in the 1970's were due to both delayed childbearing and to increasing levels of permanent childlessness. The results also indicate that (a) delayed childbearing is less prevalent among blackwomen than among non-black women, (b) education and labor force participation are important determinants of delayed childbearing, (c) the influence of education and labor force participation on delayed childbearing seems to beincreasing across cohorts, (d) education is positively associated with heterogeneity among women in their age at first birth, (d) the dispersion of age at first birth is increasing across cohorts, (f) race has an insignificant effecton childlessness, and (g) education is positively associated with childlessness, with the effect of education increasing and reaching strikingly highlevels for the most recent cohorts.

Book Description

This book discusses the biological, methodological and sociological issues that have caused men to be overlooked in demographic and sociological literature of fertility. It explores the patterns and determinants of male fertility and studies male fertility rates as compared to those of females in 43 countries and places, over time. Data used in the aggregate level analysis come from multiple sources, including the 2001 United Nations Demographic Yearbook, the 1964 to 2004 Taiwan-Fukien Demographic Yearbooks, and National Statistics Reports by the Statistics Bureau of Republic of China. To explore male fertility determinants, the book analyzes individual data from the 2002 National Survey of Family Growth (NSFG) in the United States. The findings presented here demonstrate that male fertility differs from female fertility in both rates and determinants, which suggests that female fertility cannot fully represent human fertility.
