This study examines the role of tempo effects in the fertility declines of less developed countries. These effects temporarily inflate the total fertility of a population during periods when the age at childbearing declines and deflate it when childbearing is postponed. An analysis of data from the World Fertility Surveys and the Demographic and Health Surveys demonstrates that fertility trends observed in many less developed countries are likely to be distorted by changes in the timing of childbearing. In most countries women are delaying childbearing, which implies that observed fertility is lower than it would have been without tempo changes. This pattern is most clearly documented in Taiwan, where accurate birth statistics from a vital registration system make it possible to estimate the tempo components of fertility annually from 1978 to 1993. The small but unexpected rise in the total fertility of Colombia in the early 1990s is attributed to a decline in the negative tempo distortion that prevailed in the 1980s. Similar interruptions of ongoing fertility declines may occur in the future in other countries when existing negative tempo effects are removed. 相似文献

ABSTRACT The purpose of this research is to evaluate the consequences of early childbearing decisions for women's labor force activity in later life. Within a life course framework, women's early child-bearing activities may be linked to later life decisions. Women between ages 55 and 64 are evaluated from the 1984 Survey of Income and Program Participation. Two measures of early family roles are considered: total fertility (number of children ever born) and timing of first-birth (childless, prior to age 30, and 30+). Results provide some limited support that early childbearing roles do in fact have a long-term impact on the employment decisions of women. Women who delay childbearing are somewhat more likely to remain in the labor force during their later years whereas women who remain childless are more likely to have exited the labor force. 相似文献

Fertility decline in central and eastern Europe (CEE) since the fall of the communist regimes has been driven by both stopping and postponement of childbearing: two processes that have been related to crisis and economic development, respectively. In the Western Balkans these economic and political contexts followed each other in the form of a biphasic transition. I examine whether this sequence triggered fertility responses like those observed elsewhere. Relying on three independent data sources, I cross-validate the levels of, and describe the trends in, union formation and fertility (by birth order) between 1980 and 2010. Results do not reveal widespread declines in fertility to lowest-low levels during the most acute period of crisis. The subsequent postponement of marriage and first birth was also limited, and the two-child family remains the norm. This relative resilience of childbearing patterns compared with other CEE countries is discussed with reference to the institutional context. 相似文献

This article provides the first detailed account of recent fertility trends in Iraq, with a particular focus on the changes resulting from the 2003–2011 war and the factors underlying them. The study is based on retrospective birth history data from the 2006 and 2011 Iraq Multiple Indicator Cluster Surveys (I‐MICS). Estimates from the two surveys indicate that total fertility remained stable from 1997 to 2010, at about 4.5 children per woman. However, examination of the age patterns of fertility reveals an abrupt shift in the timing of births, with adolescent fertility rising by over 30 percent soon after the onset of the war. A decomposition analysis shows that the rise in early childbearing is due to an increased prevalence of early marriage among less‐educated women. The prevalence of early marriage and childbearing among women with secondary or higher education is relatively low and has not increased after 2003. 相似文献

The National Committee on Family Planning conducted a sample survey of fertility in the Yi-yang area in September 1982. The survey was focused on the marriage and fertility status of women between the ages of 15 and 67. Results from this survey show that early marriage is still very popular. Only 40% of those surveyed delayed their marriage to a later age. There is a need to educate the people on the benefits of late marriage. In addition, statistics show that the average fertility rate for a woman was 6.8 children in 1970 and 2.35 children in 1982. This recent figure is still too high when compared with the under 1.2 figure suggested by the central government. Among the total number surveyed, only 77% have taken birth control measures, and the other 23% still have not taken any birth control measures. The phenomenon shows that popular education on late marriage and having children at a later age is still urgently needed in order to further reduce the fertility rate. Married couples of childbearing age should be taught effective birth control measures and knowledge of eugenics with better education for the next generation. In this way, the masses may participate actively and positively in the national family planning campaign. 相似文献

The expansion of female education has been promoted as a way to postpone the age at first birth. In sub‐Saharan Africa, the first cohorts to benefit from policies that expanded access to education are now reaching adulthood and beginning childbearing. I investigate whether the expansion of education in Malawi, which implemented a free primary education policy in 1994 and subsequently expanded secondary schooling, has led to a later age at first birth and whether the education gradient in fertility timing has remained stable over time. Despite increases in female grade attainment over the past twenty years, the age at first birth has not changed. Using instrumental variables analysis, I find a significant negative association between grade attainment and age at first birth, suggesting that the deterioration of school quality and the shift in the age pattern of enrollment that accompanied educational expansion may have compromised the transformative potential of education. 相似文献

This paper develops a stock adjustment model relating total expected births to conventional aggregate fertility rates for married women over 25. Each year, cohorts bear about 20 percent of their additional expected births. Aggregate U.S. rates have been consistent with expectations as expressed in surveys between 1955 and 1975; indeed, total expected births may be inferred from aggregate fertility behavior. A peculiar empirical finding is that the additional expected fertility of nonterminators has not changed since 1955, despite the dramatic decline in total expected and actual fertility. The model leads to a dynamic expression for the duration pattern of current and cumulative fertility and for the proportion of couples who have terminated childbearing. The model is also used to analyze the effects of changing contraceptive failure rates on fertility patterns. For example, a decline in “timing” failure rates increases duration-specific fertility five years later. 相似文献

This article explains that birth delays skew developing world's fertility figures. When successive groups of women who have delayed childbearing start having children, the rapid fertility decline stalls. Such change in the timing of childbearing skews the total fertility rate (TFR). Analysis of the tempo component of TFR trends in Taiwan suggests that tempo effects reduced its TFR by about 10% in the late 1970s and early 1990s and by about 19% in the late 1980s. In Colombia, on the basis of increasing mean maternal age at childbirth between the 1970s and the late 1980s, tempo distortions of the TFR during the most of the 1980s seem likely. Moreover, many developing countries are now experiencing rapid fertility declines that are in part attributable to tempo changes. These changes have accelerated past fertility transitions, but they also make these countries vulnerable to future stalls in fertility when the delays in childbearing end. Since fertility reductions caused by tempo effects lead to real declines in birth rates and hence in population growth, countries that wish to reduce birth rates can take actions that encourage women to delay marriage and the onset of childbearing. 相似文献

In this paper we examine the age pattern of sterility in a natural fertility population of 16 English parishes. We examine estimators of sterility proposed by historical demographers. We demonstrate through Monte Carolo simulation of reproductive histories that the estimators proposed earlier work well only if the ages to which the estimates pertain are substantially modified from the original formulation. The new estimates show a much larger positive effect of childbearing on sterility than would the earlier ones. We also present estimates of the age pattern of sterility due solely to the process of ageing by eliminating secondary sterility induced by childbearing. This curve rises slowly until age 40, after which the proportion sterile increases rapidly with age. We find no evidence of a sharp rise in the risk of sterility in the 30s. We find strong evidence of a decline in fecundity by examining age-specific fertility rates only for those women who are known to be fecund because they later bear children. The evidence suggests only a moderate decline until ages 35–39 and a much steeper decline thereafter.Finally, we illustrate the danger of the use of a clinical test of infertility commonly employed. We show that if women are judged to be infertile because they have not become pregnant within one year of unprotected exposure, then a large fraction of those so judged will be falsely diagnosed. We conclude that the one-year period is too short. 相似文献

Starting age and subsequent birth intervals in cohabitational unions in current danish cohorts, 1975
This paper presents some main results of an investigation by life table methods of birth interval data in cohabitational unions (marriages as well as consensual unions) in current Danish cohorts. Our results confirm previous findings that an early age at the start of recorded exposure to childbearing risk is indicative of a rapid pace and high level of subsequent fertility. The analysis modifies previous results and adds several new details regarding cohort trends and the effect of parity at the start of reported cohabitation. For each parity within a period of cohabitation, fertility differentials by reported starting age seem to have diminished from our older cohorts (of age up to 49 years in 1975) to our younger ones (of age less than 30 years in 1975). There are indications of a dramatic change in childbearing behaviour following the arrival of novel attitudes to non-marital cohabitation and childbearing in Denmark about 1967. 相似文献

By the late 1990s the average period total fertility rate in the developed world had declined to 1.6, a level substantially lower than projected in the 1970s and 1980s. This article examines recent trends and patterns in fertility in the developed world with particular emphasis on the effects and implications of changes in the timing of childbearing. The main objective is to demonstrate that while fertility in these countries is indeed low, women's childbearing levels are not as low as period measures such as the total fertility rate suggest. To obtain a full understanding of the various dimensions of fertility change. several indicators are examined, including period and cohort fertility by birth order and childbearing preferences. An analysis of these indicators demonstrates that period fertility measures in many developed countries are temporarily depressed by a rise in the mean age at childbearing. The distortion of the TFR is as great as 0.4 births per woman in Italy and Spain. These effects have been present in many developed countries since the 1970s and could continue for years into the future. But tempo effects are temporary, and once the postponement of childbearing ends—as it eventually must—the corresponding fertility‐depressing effect stops, thus putting upward pressure on period fertility. Countries with very low fertility and substantial tempo effects may well experience rises in fertility in the near future if the timing of childbearing stabilizes. Even if this happens, however, it seems unlikely that fertility will rebound to the replacement level. 相似文献

Lowest‐low fertility, defined as a period total fertility rate at or below 1.3, has rapidly spread in Europe during the 1990s. This article traces the emergence of this new phenomenon to the interaction of five factors. First, tempo and compositional distortions reduce the total fertility rate below the associated level of cohort fertility. Second, socioeconomic changes—including increased returns to human capital and high economic uncertainty in early adulthood—have made late childbearing a rational response for individuals and couples. Third, social interaction effects reinforce this behavioral adjustment and contribute to large and persistent postponement in the mean age at birth. Fourth, institutional settings favor an overall low quantum of fertility. Fifth, postponement–quantum interactions amplify the consequences of this institutional setting when combined with ongoing delays of child‐bearing. The article concludes with speculations about future trends in current and prospective lowest‐low‐fertility countries. 相似文献

Taiwan's decline in fertility is studied by using period parity progression ratios. Levels of marriage and motherhood are found to have been high and essentially constant though the late 1980s, suggesting that the decline has been due almost entirely to declines in second and higher order-births. Families with three or more children play an important role in maintaining the current level of fertility. The level of fertility would be even lower without these families. They contributed more than one-half child per woman to the total fertility rate during most of the 1980s. Total fertility rates computed from the period parity progression ratios indicate a substantially higher level of fertility than the conventional total fertility rate; they remained above or at replacement level through 1988. A formal demographic analysis suggests that the conventional total fertility rate has been depressed by shifts in age at childbearing. 相似文献

This article compares the fertility patterns of women in consensual union and marriage in 13 Latin American countries, using census microdata from the four most recent census rounds and a methodological approach that combines the own‐children method and Poisson regression. Results show that in all these countries, fertility is slightly higher within consensual union than marriage and that the age pattern of fertility is very similar in marital and non‐marital unions. Further analyses show that over the period considered, childbearing within a consensual union has changed from rare to increasingly common, although not yet mainstream, for highly educated women in most countries examined. Results show that in Latin America, at least since the 1980s, women's childbearing patterns depend on their age and on their being in a conjugal relationship, but not on the legal nature of this relationship. The similarities in reproductive behavior between marital and non‐marital unions are not confined to the socially disadvantaged groups, but apply as well to the better off. 相似文献

Data on family size by year of marriage, age at marriage, and duration of marriage, from the 1911 Fertility Census, are compared between Scotland, England and Wales, Irish county boroughs, and the rest of Ireland. While means show significant inter-country differences, from the 1880s marked similarities are found across all the countries in the pattern of fertility decline, strongly suggesting significant fertility limitation in rural Ireland well before 1911. Noting the implications for the use of rural Ireland as a natural fertility population, the data are instead compared with the Coale-Trussell and Hinde-Woods schedules. The former provides more plausible results, which imply strong period rather than cohort effects in the fertility decline. Except in rural Ireland, little evidence is found for significant fertility limitation early in marriage among younger marrying couples, but many older marrying couples appear to have stopped childbearing at very low parities from an early date. 相似文献

Most young people in the United States express the desire to marry. Norms at all socioeconomic levels posit marriage as the optimal context for childbearing. At the same time, nonmarital fertility accounts for approximately 40 % of U.S. births, experienced disproportionately by women with educational attainment less than a bachelor’s degree. Research has shown that women’s intentions for the number and timing of children and couples’ intent to marry are strong predictors of realized fertility and marriage. The present study investigates whether U.S. young women’s preferences about nonmarital fertility, as stated before childbearing begins, predict their likelihood of having a nonmarital first birth. I track marriage and fertility histories through ages 24–30 of women asked at ages 11–16 whether they would consider unmarried childbearing. One-quarter of women who responded “no” in fact had a nonmarital birth by age 24–30. The ability of women and their partners to access material resources in adulthood were, as expected, the strongest predictors of the likelihood of nonmarital childbearing. Nonetheless, I find that women who said they would not consider nonmarital childbearing had substantially higher hazards of fertility postponement and especially of marital fertility, even after controlling for race/ethnicity, mother’s educational attainment, family of origin intactness, self-efficacy and planning ability, perceived future prospects, and markers of own educational attainment and work experience into early adulthood. 相似文献

China’s middle-aged and older women suffer from poorer health than men. Using national baseline data from the China Health and Retirement Longitudinal Study (CHARLS), a survey conducted from 2011 to 2012, this article applies logistic models to investigate the association between female fertility history (parity, early childbearing, late childbearing) and middle-aged and late-life health. We find that parity is related to the mid-late-life health of women. Women with four children or more are more likely to suffer from activities of daily living (ADL) impairment and poorer self-rated health than those with one to three children. Early childbearing is associated with ADL impairment; however, the correlation is mediated by socioeconomic status. Early childbearing is related to self-rated health in later life by an indirect-only mediation effect via educational attainment and personal income. 相似文献
