In order to assess how expansion of day care facilities affects fertility, the Norwegian Family and Occupation Survey of 1988 was linked with individual register-based migration histories and time-series data on day-care coverage rates in all Norwegian municipalities. Many factors affect both the allocation of resources to day-care centers and a woman's probability of giving birth. The local coverage rate is positively associated with the probability of advancing from parity two, after control for geographical region, degree of urbanization and other confounders. This effect of day-care supply, which is significant at low coverage levels, contributed to a moderate rise in third-birth rates after the mid-1970s. However, if the aggregate employment rate for women is also regarded as a confounder, the effect of day care may actually be insignificant. Moreover, the effect fades at higher coverage levels. Finally, there are indications that second- and first-birth probabilities decline with increasing provision of day care. These results suggest that further efforts to improve the supply of private and public day care - which in Norway are likely to be motivated by non-demographic concerns - will have little stimulating effect on fertility, at least if the subsidies and quality of care remain unchanged.  相似文献

The population of Fiji consists of two major ethnic groups, Fijians and Indians; it also comprises other groups, such as Europeans, Chinese and other Pacific Islands. The 2007 Census showed that there were 56.8 % Fijians and 37.5 % Indians, with the remaining 5.7 % consisting of other groups. This paper examines ethnic variation in fertility using current fertility estimated directly from the census data. As the Fiji census continued to gather information on the relationship of mothers with their own children, this information has been used to estimate fertility trends over the past 15 years preceding the census by the application of the own-children method. Fiji has recently undergone a spectacular decline in fertility but with a marked variation between Fijians and Indians. The total fertility rate (TFR) among Indians dropped to 2.8 in 1986 and 2.5 in 1996. It continued to decline further, approaching below the replacement fertility of 1.9 in 2007. By contrast, Fijian fertility reached 3.9 in 1996. As with that of Indians, Fijian fertility also fell sharply, to 3.2 in 2007. This paper uses a decomposition analysis technique to determine the components of changes in the TFRs due to marital structure and marital fertility among Fijians and Indians, covering the intercensal periods, 1966–1976, 1976–1986, 1986–1996 and 1996–2007.  相似文献

Period fertility rates show a recent rise in the fertility of the Malay population of Peninsular Malaysia that became evident in the late 1970s, after more than fifteen years of slow but steady declines. Detailed analysis of age-parity-specific fertility rates suggests that the recent rise is largely due to a “making up” of lower order births (first, second, and third) that had been postponed by a rapid increase in age at marriage. The period trend in higher order births and cohort trends of cumulative fertility from census data point to a continued reduction in completed Malay fertility. Regional analysis shows several states on the east coast with persistent high fertility, although the revolution in marital postponement is national in scope.  相似文献

Most developing countries are in the demographic stage of early mortality, high birth rates and high rates of natural population increase. A characteristic of developing countries is that after World War ii, particularly since the 1960s fertility rates are on the decline, even though they still remain high. The fertility rate of developed countries fell from a 1950 rate of 22.9/1000 to 15/1000 in 1982, a decrease of 34.5%, whereas the fertility rate of developing countries hovered around 43/1000 between 1930-1950, 40.6/1000 during the 1960s and 33/1000 in 1982. Between 1950 and 1982 there was a decrease of 24.8%. But the main reason for this decrease is the decline in the last 20 years of the fertility rates of China and India, whose rates fell 34.9% from 1960-1980. Changes in fertility rates are influenced by the age structure of a country, as seen in the changing age structure of developing countries from 1960-80. For example, an increase in fertility rates was 1 consequence of an increase in the number of fertile women aged 15-45 from 42.6% in 1960 to 44.4% in 1980. Nevertheless, there exists some sort of birth control, whether conscious or subconscious, because the number of births per fertile woman is 3-4 fewer than the 14-15 children a woman can theoretically bear. The reason for changes in fertility rates in developing countries can be traced to marriage and family customs, and even more important, to social and economic factors. For example, Asian, African and Latin American cultures tend to support early marriages. When the fertility rates of developed and developing countries are looked at for a comparable period, then the rate of decrease for developing countries is slower than developed countries. But, if the comparison is made for a transitional period (i.e., industrialization), then the rate of decrease for developing countries is faster than for developed countries. Currently there are 25 developing countries that have attained a fertility rate of 25/1000 or lower, and 52 developing countries with a rate of 35/1000.  相似文献

The 1982 census provided detailed information on fertility in China. It recorded 20,689,704 births in 1981, producing a birth rate of 2.1%, a decrease, respectively, of 43% and more than 50% in comparison with 1952 and 1963. The birth rate has varied widely over the last 30 years, from 3.6% in the early 1950's, to 1.8% in 1961, after a planned birth program was begun, to a record high of 3.7% in 1962 following the economic recovery, to 3.3% in 1970, after a gradual decline through the 1960's. By 1981 the birth rate had declined to 2.1%, clearly resulting from the intense planned fertility promotion begun in the early 1970's. In the mid- and late 50's, urban birth rate was consistently higher than rural, with the mass move to the cities at the beginning of the People's Republic. General economic development after 1957 brought simultaneous declines of both urban and rural rates, both reaching a low point in 1961. Age structure of the population also has an influence, depending on the proportion of childbearing women in the population. In 1981, the fertility of China's childbearing women was 8.3%, lower than that of the developing countries, but higher than the developed countries. By age group, the fertility rates reached 14.7% and 23.9% respectively in women between 20-24 and 25-29 years of age; the legal marriage age is 20. The fertility rate in large cities is generally lower than that of provinces. Higher educational and socio-economic level also exert an inverse influence on fertility rates; in low socio-economic areas the rate reached 3.5%, and in more advanced areas it was held to 2.2%. In all professions with the exception of agriculture, fishing, and forestry, the percentage of families with 1 child was 81.8%. Since planned fertility was implemented, the overall fertility rate has dropped from 3% to 2%. China's fertility mode has changed to that of developed countries, with high intensity between 20 and 29 years of age. Appropriate measures should be taken to lower the fertility rate in different regions.  相似文献

In this article, we undertake an event-history analysis of fertility in Ghana. We exploit detailed life history calendar data to conduct a more refined and definitive analysis of the relationship among personal traits, urban residence, and fertility. Although urbanization is generally associated with lower fertility in developing countries, inferences in most studies have been hampered by a lack of information about the timing of residence in relationship to childbearing. We find that the effect of urbanization itself is strong, evident, and complex, and persists after we control for the effects of age, cohort, union status, and education. Our discrete-time event-history analysis shows that urban women exhibit fertility rates that are, on average, 11% lower than those of rural women, but the effects vary by parity. Differences in urban population traits would augment the effects of urban adaptation itself. Extensions of the analysis point to the operation of a selection effect in rural-to-urban mobility but provide limited evidence for disruption effects. The possibility of further selection of urbanward migrants on unmeasured traits remains. The analysis also demonstrates the utility of an annual life history calendar for collecting such data in the field.  相似文献

This paper reports the outcome of an exercise in curve fitting to annual sets of Danish age-specific fertility rates for the years 1962 to 1971 by means of least squares. Functions fitted were a cubic spline, the Hadwiger and Coale-Trussell functions, the gamma and beta densities, two versions of a polynomial, and two of Brass's relational procedures, as well as the Gompertz curve. The spline function fitted all curves far better than any of the others. The Coale-Trussell procedure and gamma density were about equal, followed by the Hadwiger function. All of these functions fit the data well. One of the polynomials fit reasonably well, but the rest of the functions were less accurate.  相似文献

After declining for many years, there are indications that fertility may be increasing among highly educated women. This paper provides a comprehensive study of recent trends in the fertility of college-graduate women. In contrast to most existing work, we find that college graduate women are indeed opting for families. Data from the Current Population Surveys and Vital Statistics Birth Data both show that fertility increases among college graduate women, especially at older ages since the mid- to late 1990s. There are also increases in fertility among less-educated women, but these are concentrated at younger ages.  相似文献

Child care arrangements and fertility: An analysis of two-earner households   总被引:2,自引:0,他引:2  
The determinants of child care arrangements and relations between child care and fertility are examined using data on two-earner households from the 1976 National Survey of Family Growth. We find that the probability of relying on market arrangements is higher among families in which the husband's income, the wife's wage, and the level of the wife's labor supply are high; these households are likely to benefit the most from subsidies to the market forms of care that are small relative to the total cost of care (e.g. the present system of tax credits). In addition, parental education, family size, child's age, race, religion, and place of residence have important influences on the choice of child care mode. When other factors are held constant, reliance on a relative for child care is positively associated with intentions to have further children among couples with infants and preschoolers.  相似文献

Between 1998 and 2008 European countries experienced the first continent-wide increase in the period total fertility rate (TFR) since the 1960s. After discussing period and cohort influences on fertility trends, we examine the role of tempo distortions of period fertility and different methods for removing them. We highlight the usefulness of a new indicator: the tempo- and parity-adjusted total fertility rate (TFRp*). This variant of the adjusted total fertility rate proposed by Bongaarts and Feeney also controls for the parity composition of the female population and provides more stable values than the indicators proposed in the past. Finally, we estimate levels and trends in tempo and parity distribution distortions in selected countries in Europe. Our analysis of period and cohort fertility indicators in the Czech Republic, Netherlands, Spain, and Sweden shows that the new adjusted measure gives a remarkable fit with the completed fertility of women in prime childbearing years in a given period, which suggests that it provides an accurate adjustment for tempo and parity composition distortions. Using an expanded dataset for ten countries, we demonstrate that adjusted fertility as measured by TFRp* remained nearly stable since the late 1990s. This finding implies that the recent upturns in the period TFR in Europe are largely explained by a decline in the pace of fertility postponement. Other tempo-adjusted fertility indicators have not indicated such a large role for the diminishing tempo effect in these TFR upturns. As countries proceed through their postponement transitions, tempo effects will decline further and eventually disappear, thus putting continued upward pressure on period fertility. However, such an upward trend may be obscured for a few years by the effects of economic recession.  相似文献

Crude birth rates for the Negro population of the United States indicate that fertility declined while Negroes remained in the South and them climbed in the last twenty-five years as Negroes became urbanized. Cohort rates show more precisely the effects of the Depression upon childbearing as well as the magnitude and persistence of the post-Depression rise in fertility. More Negro women now become mothers, average family size has increased, and the proportion of women bearing six, seven, or eight children has risen. Negro fertility has risen despite the urbanization of Negroes and improvements in their socio-economic characteristics. Negro fertility rates present the paradox of falling when demographic transition theory would predict the maintenance of high rates and then rising when a decline would be expected. Urbanization does not appear to have reduced Negro fertility. Traditionally, urban living has dampened childbearing in two ways—first, health conditions in cities were inferior to those of rural areas, and thus urbanization affected fecundity adversely; second, city residents are more likely to know about and adopt birth control than rural residents. Negroes migrated to cities at the very time when diseases were being controlled and when public health and welfare facilities were being expanded to serve all residents. This has contributed to higher Negro fertility rates. If fertility rates are to fall because of family planning, not only must birth control be available but there must be a desire to limit family size. Such a desire may be linked to opportunities for social mobility. Negroes have not been assimilated into urban society as previous in-migrant groups were, and opportunities for mobility have been restricted. For these reasons Negroes may be slow to adopt stable monogamous families and the intentional control of fertility.  相似文献

In recent years fertility statistics in the Australian Bureau of Statistics (ABS) publication Births, Australia have suffered from a number of issues, including delayed receipt of registration data from the Registrars and computer processing errors. They prompt questions about the quality of these statistics for measuring the level of fertility and its year-to-year changes. The aim of this paper is to compare three sets of fertility statistics, (1) ABS birth registrations, (2) ABS births by year of occurrence, and (3) births in the Australian Institute of Health and Welfare National Perinatal Data Collection (NPDC), at the national and state/territory scales. Annual births by state/territory of usual residence from the three data sources were obtained for the period 2004–2013 or 2004–2014. Recast Estimated Resident Populations from the ABS were used to calculate Total Fertility Rates. For some states and territories there are non-trivial differences in fertility as recorded by the three data sources. In Queensland the trend in fertility according to ABS birth registrations is quite different from that based on the NPDC; in Tasmania and the Northern Territory birth registrations exceed NPDC births by a notable margin. There appears to be more uncertainty about the levels and annual changes in Australian fertility than many users of the data may realise. All three fertility datasets seem to possess some limitations. It is suggested that a new Australian fertility database be created which employs data linkage to incorporate both birth registrations and perinatal data.  相似文献

This paper illustrates a method of studying changes in vital rate schedules which have no effect on the intrinsic rate of population growth. These changes are described as compensating changes in fertility and mortality. The analysis proceeds from the discrete perspective of Leslie matrices, wherein the central idea is to establish the set of all compensating changes by identifying that class of Leslie matrices which possess the same positive eigenvalue, λ1. A root-squaring technique is adapted for the purpose of estimating λ1. Finally, a variety of compensating fertility and mortality changes is illustrated using data from Japan.  相似文献

The sample survey of fertility, in Shanghai city and Shanxi and Hebei provinces of China in 1985, provided plentiful data about fertility, marriage, contraceptive usage and breastfeeding in terms of The World Fertility Survey Model. The data, along with Bongaarts' model, was utilized to analyze the relation between several proximate determinants and fertility changes. When comparing these three geographic areas, the largest difference was breastfeeding and the smallest one was non- contraceptive usage. It was very different from the results of The World Fertility Survey in developing countries in 1977. The difference of marriage indexes among three areas was close to that of breastfeeding; but for the effects on induction of fertility, marriage index surpassed breastfeeding. There were two models showing effective efficacy on fertility decline. One was the Shanghai model, in which much more effect came from marriage delay, accounting for 71%; another was the Hebei model, induction of fertility was caused by contraceptive usage, about 53%. Both indicated that the major factor affecting fertility decline was the family planning program. Otherwise, it seemed to indicate that different factors such as social, economic development indirectly decreased fertility through family planning programs.  相似文献

Abstract In an earlier paper a working model of marital fertility was presented.(1) That model grew out of a close study of Becker's economic model for fertility analysis.(2) Becker's model was modified in several respects in order to meet a number of major objections levelled against it by Judith Blake, Deborah Freedman, and others.(3) The purpose of the present paper is to examine how far the model presented earlier can serve as a 'binder' for the interpretative schemes now available in the literature on fertility differentials. More specifically, the objective is to identify the underlying explanatory factors of a number of analytical hypotheses concerning fertility differentials, and to examine whether the factors thus identified can be located in the fertility model presented in the earlier paper.(4) Little attention will be paid to the causal directions, if any, recognized in the hypotheses studied, nor will we attempt to provide a systematic review of empirical findings.  相似文献

Summary Many recent fertility studies in developing societies put forward the hypothesis of a negative relation between economic class and fertility. Data showing a positive relationship are frequently dismissed a priori as resulting from the reporting errors of illiterate women. This study draws on data from Indonesia's 1971 Census, a 1973 sample survey of fertility and mortality, and an intensive community study in Java, to argue that an observed positive relation between class and fertility is real, and is related to differences in patterns of marital disruption, postpartum abstinence, and fecundity. The positive relation may be reversed in the future as changes in these patterns, and the impact of the national family planning programme, affect the family structure of each class differently. Had the positive relation in this context been attributed offhand to reporting errors, these important socio-economic changes would have been misunderstood, and possibly ignored.  相似文献
