Birth spacing dynamics in China: The cases of Hebei and Shaanxi provinces

Even as fertility has declined in China in the last several decades, the first and second birth intervals have become shorter over time and the probability of having a second child has increased since the late 1970s. This increase in the probability of conception seems to be contradictory to the Chinese government's birth planning strategy which explicitly stresses timing and parity. Using retrospective survey reports from 1985 in Hebei and Shaanxi provinces, the study explored this paradox. The study revealed several findings: (1) government intervention, especially the one-child policy of the late 1970s, had a strong, unexpected influence on early conception in China; (2) the timing and probability of having a first birth were associated with macrosocial forces and familial relationships; and (3) the timing and probability of having a second birth were associated with biosocial, familial as well as macro-social characteristics.Abbreviations CBR crude birth rate - DPSB Department of Population Statistics, State Statistical Bureau, China - TFR total fertility rate This article is based on a paper presented at the 1991 Annual Meeting of the Population Association of America, Washington, DC, 21–23 March 1991.     

Labour force participation and marital fertility of Italian women: The role of education

This paper uses data from the 1993 Survey of Household Income and Wealth conducted by the Bank of Italy in order to estimate a reduced form purist model of female marital fertility and labour force participation. It focuses in particular on the effect of formal education on both fertility and labour force participation, and accounts for the potential endogeneity of education. Our estimates show that increasing education up to the upper secondary level exerts ceteris paribus a positive effect on marital fertility at ages 21–39 and that highly educated women postpone fertility and have a higher labour market attachment.I wish to thank participants at the 15 ^th Annual Conference of the European Society for Population Economics 2001 (Athens), the 16 ^{t h} Italian Conference of Labour Economics 2001 (Florence), especially my discussant Emilia Del Bono, the Royal Economic Society Annual Conference 2002 (Warwick), Luca Mancini, Jeremy Smith and the anonymous referee of this Journal for useful comments.

Household fertility responses following communism: Transition in the Czech Republic and Slovakia

In central Europe fertility fell during transition from centrally planned to market oriented economies. Families reevaluated fertility plans facing new wages, reduced child-care subsidies, and economic uncertainty. Using micro-data from 1984 and 1993 in the Czech Republic and Slovakia, this paper relates fertility changes following Communism to wages, pricesand risks. Earnings have little impact on fertility timing during transition, though age, job uncertainty, and children conceived during Communism do. In the Czech Republic, changed fertility demand parameters account for much of thefall in fertility. In Slovakia a sizable proportion results from predictable responses to changed incentives.I would like to thank my Czech collaborators Pavel Mahonn, Petr Mateju, and Jiri Vecernk for enabling this empirical work to proceed; T. Paul Schultz, and Jenny Hunt and seminar participants at Yale University, the NEUDC, and the Population Association of America annual meetings and two anonymous referees for helpful comments.

Socioeconomic determinants of fertility in China

This paper reports the first set of estimates of the socioeconomic determinants of fertility in China using micro-data available from China's 1985 In-Depth Fertility Survey. Based on existing microeconomic theories of fertility, an econometric model was specified and estimated. The results indicate that even after age, marriage duration and child mortality are taken into account, education level of the woman, occupational status of the husband, the place of former and current residence, sex preference for boys, durable goods ownership, and family structure affect fertility. For the middle cohorts (aged 25–34 years in 1985), the relationship between fertility and education takes the form of a J-shaped curve.This paper is drawn from Essay II of my Ph. D. thesis submitted to McMaster University. I am grateful to Frank Denton and Byron Spencer for discussion in connection with the thesis and comments on earlier versions of this paper, to Ronald Lee, the external examiner of the thesis, for many insightful comments, and to Martin Dooley, Lonnie Magee and two anonymous referees for very helpful suggestions.

White and nonwhite trends in first birth timing: Comparisons using vital registration and current population surveys

The magnitude of racial differences in first birth timing vary greatly depending upon the data sources from which they are estimated. Vital registration data (Heuser 1976; with updates from the National Center for Health Statistics 1974–1990) show that in recent years nonwhites have higher risks of a first birth at virtually all ages compared to whites. As a result very large and historically novel differentials in childlessness are forecast using these data (see Rindfuss et al. 1988; Chen & Morgan 1991; Morgan & Chen 1992). However, retrospective fertility history data collected from the 1980, 1985 and 1990 Current Population Surveys (CPS) suggest much smaller racial differences in completed childlessness and isolate racial differences in probabilities of first births at young ages. Differences also exist between theses two series for whites prior to the mid-1960s but not afterwards. Reasons for these differing estimates are suggested and examined. We conclude that a substantial portion of the differences result from an accumulation of biases in the vital registration estimates that affect primarily estimates of first birth timing. Thus, the CPS data provide a more firm basis for racial comparisons of first birth timing.     

Did the association between fertility and female employment within OECD countries really change its sign?

Recent literature finds that in OECD countries the cross-country correlation between the total fertility rate and the female labor force participation rate, which until the beginning of the 1980s had a negative value, has since acquired a positive value. This result is (explicitly or implicitly) often interpreted as evidence for a changing sign in the time-series association between fertility and female employment within OECD countries. This paper shows that the time-series association between fertility and female employment does not demonstrate a change in sign. Instead, the reversal in the sign of the cross-country correlation is most likely due to a combination of two elements: First, the presence of unmeasured country-specific factors and, second, country-heterogeneity in the magnitude of the negative time-series association between fertility and female employment. However, the paper does find evidence for a reduction in the negative time-series association between fertility and female employment after about 1985.I benefited from stimulating discussions with Arnstein Aassve, Pau Baizan, Francesco Billari, Henriette Engelhardt, Hans-Peter Kohler and Alexia Prskawetz and a seminar in Rostock.

Effect of childbearing on Filipino women's work hours and earnings

The effects of childbearing and work sector on women's hours and earnings in the 8 years following an index pregnancy were examined in a cohort of more than 2,000 women in the Cebu Longitudinal Health and Nutrition Survey. Change in cash earnings and hours worked were each modeled jointly with sector of labor force participation using an estimation strategy that deals with endogeneity of childbearing decisions and selectivity into sector of work. Two or more additional children born in the 8 year interval significantly reduced women's earnings, while having an additional child under 2 years of age in 1991 reduced hours worked.

Skill premium effects on fertility and female labor force supply

In the last twenty years the United States has seen a positive relationship between female labor supply and total fertility rates, which differs from the pattern observed over the preceding years. We construct a general equilibrium overlapping generations model capable of generating this changing relationship between fertility and female labor supply. We argue that skilled biased technological change in recent decades has increased the skill premium and has therefore decreased the relative cost of (unskilled) child care services. The positive effect of the increase in female mean wages on fertility rates, and the inducement for labor force participation provided by the reduction in the relative cost of child care services, generated the positive relationship between fertility rates and female labor force participation in the last two decades.All correspondence to Amaia Iza.

流动人口的生育意愿与生育行为差异研究

文章利用中国人民大学人口与发展研究中心于2009年在北京朝阳区、广东东莞市和浙江诸暨市组织进行的流动人口调查数据,分析了流动人口的生育意愿与生育行为之间的关系。研究发现,流动人口中既存在生育意愿与生育行为悖离的一面又有一致的一面,在4个维度上均有所表现,在时间、间隔和性别上二者更多的表现为悖离,在数量上更多的表现为一致。研究还发现,年龄、初婚年龄、初育年龄、受教育程度、职业角色、已有孩子的性别结构等对生育意愿与生育行为的悖离有显著影响。     

A note on the changing relationship between fertility and female employment rates in developed countries

In this paper we look at a panel of OECD aggregate fertility and labor market data between 1970 and 1995 and we report some striking recent developments. Total Fertility Rates (TFR) were falling and Female Participation Rates (FPR) were increasing, conforming to a well known long-run trend. Along the cross-sectional dimension, the correlation between TFR and FPR was negative and significant during the 1970's and up to the early 1980's. This seemed consistent with secular comovements. However, by the late 1980's the correlation had become positive and equally significant. We discuss our findings within the framework of standard neoclassical models of fertility and labor supply adapted to macro data, as in Butz and Ward (1979).

Sex preference versus number preference: the case of Korea

The author argues that the effect of sex preference must be disentangled from the effect of number preference in Korea. This study tests--with hazard models--the effect of the number of previous children on the next birth according to the sex composition of previous children. Data were obtained from the 1974 Korean Fertility Survey. This paper also analyzes the timing of childbearing in recent periods in order to determine whether replacement-level fertility is temporary or permanent. The ideal number of children declined from 3.9 children in 1965 to 2.1 in 1991. The age-specific fertility rates for ages 20-24 years declined rapidly during the late 1980s. The fertility rates among women aged 25-29 years and 30-34 years increased during 1985-90. The proportion of fertility among women aged 20-29 years increased from 67.9% in 1975 to 86.6% in 1984. Women born in the late baby boom period of the late 1950s to mid-1960s reached prime reproductive age during the late 1980s and 1990s, but the crude birth rate remained about the same during 1985-92. A higher percentage of women (22.4%) born during 1955-59 remained single in 1990. During 1960-90, the percentage of women aged 20-24 years who were married declined. These trends indicate later age at childbearing and an explanation for the temporary nature of below-replacement fertility in the late 1980s. Korean women did not want to have more than 2 children, and the interval between first and second births increased since 1985. Among pregnancies of parity 2 conceived since 1985, over 90% of women with at least one son ended subsequent pregnancies by abortion compared to only 59% without sons. Hazard models of 1974 data reveal that son preference had an important effect on fertility. Fertility was higher among women with only daughters. Findings suggest that the value of sons must be measured at the societal and not at the individual level.     

An assessment of the own-children method of estimating fertility by birthplace in Australia

This paper examines the validity of the own-children method of fertility estimates derived from the 1991 Census by a detailed investigation of mortality assumptions, the presence of non-own children, age misreporting and undercount. A comparison of fertility measures derived alternatively from the census using the own-children method and from vital statistics for the period 1987–91 indicates remarkably similar rates for Australia-born women, and plausible results for long established migrant groups. The own-children fertility levels for some recently arrived migrant groups, however, were found to be misleading. It is suggested that the own-children method is useful for the study of differential current fertility in Australia. Revised version of an essay awarded the W.D. Borrie Prize (graduate section), 1997, and presented to the session: Advances in methods for the analysis of demographic data of the 23rd General Conference of the International Union for the Scientific Study of Population, 11–17 October, Beijing. This paper is based on the author’s PhD thesis entitled:Fertility patterns of Australian selected immigrant groups, 1977–91.     

A reply to Walker’s note: A comment on Taşiran’s ‘Wage and income effects on the timing and spacing of births in Sweden and in the United States’

Walker (1997) criticizes one of the conclusions in my book Tas?\iran (1995), that Heckman and Walker’s very high negative wage rate and positive income effects on Swedish fertility are very sensitive. In this paper, I explain, first, that my results are not only based on the series Walker mentions, but also on other series in both SFS and HUS data sets. Second, the combined aggregate and micro wage series he criticizes is mainly derived with Heckman and Walker. Third, by discussing the points he raises for the combination strategy, I show that his revised results are also supporting my conclusion.

Fertility and education premiums

This study examines households fertility variations in response to expected permanent shifts in the return to education. Wage premiums measurethe return to education because their long-run movements are driven by factors exogenous to the fertility process. The results indicate that high education parents fertility responds negatively to changes in the expected return to college and negatively to changes in the expected return to high school. On the other hand, the fertility of low education parents does not vary with changes to expected returns to education. These results can be consistently interpreted within a standard quality/quantity model of endogenous fertility.I am grateful to seminar participants at Penn State University, Virginia Tech.

Child schooling in Peru: Evidence from a sequential analysis of school progression

Primary enrolment rates are very high in Peru, but so are the failure and drop-out rates. Thus an understanding of the nature of child schooling should consider school progression from primary to secondary and higher levels, taking account of the conditional sequence with the previous level and self-selection into the next higher level of schooling. Using a unique correlated sequential probit model with unobserved heterogeneity the present paper does so and obtains richer results, argued to be better than the standard static estimates. It is shown that the same set of individual/parental/household characteristics may affect different levels of schooling differently.The author is much grateful to the Managing Editor and also the Journal referees for their helpful and constructive comments.

Quality of care in Peru: measuring its impact. Field report

A report published in 1995 by the Population Council described the impact of the quality of family planning services on the incidence of unplanned pregnancy in Peru. This report followed a 1994 study that assessed the impact of quality on contraceptive usage by linking data from Peru's 1991-92 Demographic and Health Survey (DHS) and a 1992 Peru Situational Analysis study of the status of family planning (FP) services at 3000 individual service delivery points. The 1995 study added data from a follow-up survey of a sample of the DHS respondents. The 1994 study used an innovative quality of care index that measured the quality of FP services available in a geographic area to women with partners living nearby. This index was then assigned to every woman in the area and correlated with her use of modern contraceptives. The analysis revealed that availability of high-quality FP services greatly increased the number of women using modern contraception. The 1995 study analyzed the impact of quality of care on rates of unintended pregnancy and found that the percentage of unwanted births was significantly higher in areas with low-quality FP services. The researchers note that these results only hint at a relationship between quality of care and reproductive behavior and that the findings should be interpreted conservatively. However, the studies support the importance of investing in quality FP care.     

Ansley J. Coale on Increases in Expectation of Life and Population Growth

The rapid decline in mortality after the end of World War II, in combination with a much slower downward adjustment of fertility, resulted in an extraordinary acceleration of world population growth. In a contribution prepared for the 1959 Vienna conference of the International Union for the Scientific Study of Population, Ansley J. Coale présented a concise and spirited exploration of the influence of mortality and fertility on the levels and patterns of growth and on the distribution of the population by age. Using the stable population model as his tool of exploration, Coale présents a comparative analysis of the implications of movements between stable states, making imaginative illustrative assumptions on changes over time and highlighting the often surprising and counterintuitive results of such calculations. The full text of this article, omitting summaries in English and French, is reproduced below from pp. 36–41 in Union Internationale pour I?étude scientifique de la population, Internationaler Bevölkerungskongress, Wien:Im Selbstverlag, 1959. Ansley Coale was one of the most prominent figures in demography in the second half of the twentieth century. He was born in 1917 and was educated at Princeton University. He spent his entire professional career at Princeton, as a member of the economics faculty and in association with the Office of Population Research, of which he was director from 1959 to 1975. In 1967/68 he was president of the Population Association of America, and from 1977 to 1981 he was president of IUSSP. His many scientific works include Population Growth and Economic Development in Low‐Income Countries (1958), coauthored with Edgar M. Hoover, a book that was highly influential in shaping the international population policy agenda from the 1960s on—lately receiving renewed attention as a predictor of the “demographic dividend” benefiting economies as a result of the transition to low fertility. He was initiator and leader of the Princeton project exploring the causes of the decline in marital fertility in Europe, culminating in the 1986 book, coedited with Susan C. Watkins, The Decline of Fertility in Europe. His most lasting contribution to population studies, however, was in the field of formal demography, as both teacher and scholar. His research in this area is exemplified by the 1972 book The Growth and Structure of Human Populations: A Mathematical Investigation, and in the application of demographic models to the estimation and analysis of population data. Ansley Coale died on 5 November 2002, at the age of 84.     

The pattern of birth spacing during Taiwan's demographic transition

This paper considers the impact of an extended family structure on the fertility behavior of married women in Taiwan. A sequential duration model is applied to identify the differences in fertility behavior during the early and latter stages of a woman's reproductive period. Heterogeneity adjustments which correct the respondent-specific characteristics are also implemented. It is found that living with the husband's parents has an impact on the wife's fertility only at the early stage of her childbearing period, and that the subjective son preferences together with the objective fact of no son in the previous 2 births do force a wife to expedite her third birth. These results are robust across different cohorts during the demographic transition and under different specifications of hazard functions. We thank an anonymous referee for his or her valuable comments and suggestions. Responsible editor: Junsen Zhang.     

Time series analysis of fertility and female labor market behavior

Cointegration methods are employed to investigate relations among total fertility, female wages, labor force participation, educational attainment, and male relative cohort size. Two long run relations among the series are found, and these are identified as a fertility and a labor supply equation. All covariates enter into these relations with significant coefficients and theoretically plausible signs. Innovation analysis shows that both fertility and female labor force participation respond to changes in relative cohort size in directions consistent with the Easterlin hypothesis. Female labor force participation responds significantly to fertility shocks, but reverse effects are insignificant.All correspondence to Robert McNown.

Model fertility schedules: variations in the age structure of childbearing in human populations

The nature of the roots for a set of fertility functions were explored in this study, resulting in tables from creation of a family of model fertility schedules. These model fertility schedules accurately represent the full range of age structures of fertility in large populations; they have close fit to various accurately recorded fertility schedules of very different form. The text for the tables includes discussions of: 1)the basis for the fertility schedules, 2)the age structure of the proportion ever married (G(a) specified by 2 parameters, 3)single parameter specified age structure of marital fertility, 4)the similarity of model schedules of age specific fertility to the age pattern of fertility in actual populations, 5)model fertility schedules' suitability during changing nuptuality. Possible uses of the schedules and their application to different countries (England, Wales, Peru) are also described.
