Available in PDF, EPUB and Kindle. Book excerpt: Fertility, Biology, and Behavior: An Analysis of the Proximate Determinants presents the proximate determinants of natural fertility. This book discusses the biological and behavioral dimensions of human fertility that are linked to intermediate fertility variables. Organized into nine chapters, this book begins with an overview of the mechanisms through which socioeconomic variables influence fertility. This text then examines the absolute and relative age-specific marital fertility rates of selected populations. Other chapters consider the trends in total fertility rates of selected countries, including Colombia, Kenya, Korea, Indonesia, Mexico, Pakistan, France, and United States. This book discusses as well the effects of deliberate marital fertility control through contraception and induced abortion. The final chapter deals with the management of sex composition and implications for birth spacing. This book is a valuable resource for reproductive physiologists, social scientists, demographers, statisticians, biologists, and graduate students with an interest in the biological and behavioral control of human fertility.

Available in PDF, EPUB and Kindle. Book excerpt: The effects on fertility of its 3 major proximate determinants were examined -- marriage, contraception, and postpartum infecundability. The model of Bongaarts was applied both at the national level and for residence and education subgroups of 29 World Fertility Surveys (WFSs). Using this large body of data, both methodological and substantive issues were addressed. The methdological parts of the report assessed the sensitivity of the estimates to alternative modes of constructing the components of the model. In the substantive analysis, the objective was to identify the sources of national and subnational variation in fertility in a large number of developing countries at varying stages of fertility transition. Possibly the most striking substantive findings concerned the nature of the compensating effects at the aggregate level of the 3 main proximate determinants. Cross-sectionally, the fertility increasing effect of shorter durations of postpartum infecundability among the more modern strata was almost always more than counterbalanced by the impact on fertility of nuptiality and contraceptive use. This suggests that the time lags between declines in breastfeeding and compensating movements in contraception and nuptiality were normally short in the contemporary developing world. The detailed analysis of residence and educational differentials in the proximate determinants revealed considerable regional and national diversity in the source of fertility differentials. In general, the negative associations between urbanity and fertility and between maternal schooling and fertility can be attributed to nuptiality and contraceptive effects of comparable size outweighing contrary lactation effects of half the size. In Africa, nuptiality, contraception, and breastfeeding were relatively less affected by urbanity and schooling than in the other regions. Equivalent differences of about 8 children between estimated total fecundity and observed fertility in Asia and the Americas came about through markedly different combinations of contraceptive and breastfeeding behavior, with breastfeeding of much greater importance in Asia and contraception in the Americas.

Download or read book The Fertility Revolution written by Richard A. Easterlin and published by University of Chicago Press. This book was released on 1985-10 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: For most of human history a "natural fertility" regime has prevailed throughout the world: there has been almost no conscious limitation of family size within marriage, and women have spent their reproductive lives tied to the "wheel of childbearing." Only recently in developed countries has fertility been brought under conscious control by individual couples and childbearing fallen to an average of two births per woman. The explanation of this "fertility revolution" is the main concern of this book. Richard A. Easterlin and Eileen M. Crimmins present and test a fertility theory that has gained increasing attention over the last decade, a "supply-demand theory" that integrates economic and sociological approaches to fertility determination. The results of the tests, which draw on data from four developing countries—Colombia, India, Sri Lanka, and Taiwan—are highly consistent, though a number of the conclusions are likely to arouse controversy. For example, couples' motivation for fertility control appears to be the prime mover in the fertility revolution, rather than access to family planning services or unfavorable attitudes toward such services. The interdisciplinary approach and nontechnical exposition of this study will attract a wide readership among economists, sociologists, demographers, anthropologists, statisticians, biologists, and others.

Available in PDF, EPUB and Kindle. Book excerpt: John Bongaarts' proximate determinants model of fertility has accounted for over 90 percent of variation in the total fertility rate (TFR) of primarily developing nations and historical populations. Recently, dramatically low fertility rates across the globe have raised questions regarding whether this model could be applied to exclusively below-replacement nations. This study follows Knodel, Chamratrithirong, and Debavalya's 1987 analysis of fertility decline in Thailand by conducting in-depth case studies of the proximate determinants in two low fertility countries over time: South Korea, where fertility is well below the level of replacement, and the United States, where fertility has hovered around replacement level for many years. Then, the fertility-inhibiting effect of the proximate determinants is assessed by comparing the quantitative index representing each determinant measured in the 1960s/1970s with its measurement in the 2000s. For both years, I consider the fertility level that would prevail in the determinant's presence as well as the level that would exist in its absence. Finally, I use each of the indices to calculate the TFR and assess how the strength of the model varies over time in the two countries. Ultimately, results indicate that the proximate determinants model does not offer a clean picture of the fertility level in either South Korea or the United States; when trends uncovered by the case studies are compared to the results of the quantitative analysis, a number of inconsistencies are revealed. This suggests that certain components in the model may need to be respecified for more effective application in low-fertility contexts. However, that is not to say that it offers no insight into fertility at all or that it is no longer a useful tool. On the contrary, it is shown that the proximate determinants model holds a lot of potential for analysis in low-fertility nations. The implications of these results, as well as the need for improvements in international data collection efforts, are also discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Essay from the year 2002 in the subject Geography / Earth Science - Physical Geography, Geomorphology, Environmental Studies, grade: 1.1 (A), Oxford University (New College), 6 entries in the bibliography, language: English, abstract: Fertility is directly determined by so-called intermediate fertility variables or proximate determinants which are, in turn, affected by indirect determinants such as socio-economic, cultural and environmental variables. Many different proximate determinants influence fertility and the relationship between them and the level of fertility can be analysed using a comprehensive model. The result of this analysis shows that variations in four factors - marriage, contraception, lactation and induced abortion - are the primary proximate causes of fertility differences among populations. While fertility variations can always be traced to variations in one or more of the intermediate variables, the scope for variation differs among the variables as does their degree of influence in different societies and over time within societies.
