Only a few rich nations are currently at replacement levels of fertility and many are considerably below. We believe that changes in the status of women are driving fertility change. At low levels of female status, women specialize in household production and fertility is high. In an intermediate phase, women have increasing opportunities to earn a living outside the home yet still shoulder the...
The objective of this study is to examine the socioeconomic and intervening determinants of fertility control in Korea. The conceptual framework applied here is based on the synthesis framework of fertility control developed by Easterlin and Crimmins. The data came from the 1974 Korean National Family Survey, which was conducted as part of the World Fertility Survey. The study focuses on the...
Effects of Fertility Decline on Family Well Being: Opportunities for Evaluating Population Programs*
The paper considers the association between fertility and family outcomes. Voluntary population programs are supported to help people control their fertility and improve their lives, but just how strong is this link? Evaluations of family planning programs rarely isolate the contribution of policies to fertility reduction and thereby to the long run welfare of families. Many other developments ...
Period fertility rates fell to previously unseen low levels in a large number of countries beginning in the early 1990s. The persistence of Total Fertility Rates under 1.3 raised the possibility of dramatic, rapid population aging as well as population decline. In an analysis of recent trends, we find, however, a widespread turn-around in so-called “lowest-low” fertility countries. The reversal...
Longer lives and fertility far below the replacement level of 2.1 births per woman are leading to rapid population aging in many countries. Many observers are concerned that aging will adversely affect public finances and standards of living. Analysis of newly available National Transfer Accounts data for 40 countries shows that fertility well above replacement would typically be most beneficia...
This paper shows how fertility is determined in a model that assumes the existence of child care services. When child care services exist, two stable multiple equilibria result: One is a stable, steady state that brings about low fertility with low labor participation; the other, a stable state that brings about high fertility with high labor participation. Moreover, this paper also analyzes th...
Family formation changed dramatically over the 20th century in the United States. The impact of these changes on childbearing has primarily been studied in terms of nonmarital fertility. However, changes in family formation behavior also have implications for fertility within marriage. The authors used data from 10 fertility surveys to describe changes in the timing of marital childbearing from...
Thailand is 1 of the third world countries in which a very substantial fertility decline has occurred during the last 2 decades. However, there has been some recent concern, based on fertility rates derived from 3 national contraceptive prevalence surveys conducted in 1978/1979, 1981, and 1984, that the fertility decline may have lost momentum at a level well above replacement fertility. New ...
This paper investigates whether there has been a fundamental change in the importance of economic conditions on fertility. Through the 1980s econometric studies had found at best a mixed, neutral or negative effect of economic conditions on fertility. Notably, Butz and Ward (1979) concluded that fertility was counter-cyclical, with fertility falling in good times, as the opportunity costs of ch...
As survival rates improve for pediatric cancers, increased attention has been paid to late effects of cancer therapy, in particular, infertility. Fertility preservation options are available for pre- and postpubertal cancer patients; however, many providers lack knowledge regarding options. The aim of this article is to provide a comprehensive synthesis of current evidence and recommendations r...
