Understanding the sex ratio in India: A simulation approach
Authors: Griffiths Paula , Matthews Zoë , Hinde Andrew 
Published: February 2007

Abstract
The highly masculine sex ratio in India has increased substantially in the twentieth century, in contrast to most other countries in the world. Competing arguments alternatively posit underenumeration, highly masculine sex ratios at birth, or excess female mortality throughout the life course as the factors underlying the level of the overall sex ratio; these arguments have not been resolved. Based on population projections that simulate population dynamics, our findings show that small differences in mortality at young ages, persisting over a long period, as well as a sex ratio at birth of 106 males per 100 females, result in a highly masculine population sex ratio.
The mechanisms mediating the effects of poverty on children’s intellectual development
Authors: Guo Guang , Harris Kathleen Mullan 
Published: February 2007

AbstractAlthough adverse consequences of poverty for children are documented widely, little is understood about the mechanisms through which the effects of poverty disadvantage young children. In this analysis we investigate multiple mechanisms through which poverty affects a child’s intellectual development. Using data from the NLSY and structural equation models, we have constructed five latent factors (cognitive stimulation, parenting style, physical environment, child’s ill health at birth, and ill health in childhood) and have allowed these factors, along with child care, to mediate the effects of poverty and other exogenous variables. We produce two main findings. First, the influence of family poverty on children’s intellectual development is mediated completely by the intervening mechanisms measured by our latent factors. Second, our analysis points to cognitive stimulation in the home, and (to a lesser extent) to parenting style, physical environment of the home, and poor child health at birth, as mediating factors that are affected by lack of income and that influence children’s intellectual development.
Diverging fertility among U.S. women who delay childbearing past age 30
Authors: Martin Steven P. 
Published: February 2007

Abstract
In this paper I examine the evolving association between educational attainment and the timing of births. In the late 1970s, women with four-year college degrees had lower first birth rates before age 30 than women with less education, but rates of first births were similar for the two groups after age 30. From the 1970s to the 1990s, first birth rates decreased before age 30 for all women, but increased after age 30 only for women with four-year college degrees. Parity 2 birth rates also increased for college graduates with a first birth after age 30. These results document widening educational differences in fertility timing between 1975 and 1995, which may reflect period changes at later ages in women’s work and family lives.
Marital protection and marital selection: Evidence from a historical-prospective sample of American men
Authors: Murray John E. 
Published: February 2007

Abstract
Whether marriage causes people to live longer or whether healthier people select into marriage is an open question. In this study I followed a sample of men from age 18 to first marriage and ultimately to death. Health in early adulthood was represented by height and weight around age 20. The probability of ever marrying and the conditional probability of marriage in a given time period were lower for smaller men and greater for larger men. Marriage significantly lowered mortality risk even after controlling for health in early adulthood. Thus I found support both for selection into marriage and for protective effects of marriage.
Estimating wealth effects without expenditure data—or tears: An application to educational enrollments in states of India
Authors: Filmer Deon , Pritchett Lant H. 
Published: February 2007

Abstract
Using data from India, we estimate the relationship between household wealth and children’s school enrollment. We proxy wealth by constructing a linear index from asset ownership indicators, using principal-components analysis to derive weights. In Indian data this index is robust to the assets included, and produces internally coherent results. State-level results correspond well to independent data on per capita output and poverty. To validate the method and to show that the asset index predicts enrollments as accurately as expenditures, or more so, we use data sets from Indonesia, Pakistan, and Nepal that contain information on both expenditures and assets. The results show large, variable wealth gaps in children’s enrollment across Indian states. On average a “rich” child is 31 percentage points more likely to be enrolled than a “poor” child, but this gap varies from only 4.6 percentage points in Kerala to 38.2 in Uttar Pradesh and 42.6 in Bihar.
Variance effects in the bongaarts-feeney formula
Authors: Kohler Hans-Peter , Philipov Dimiter 
Published: February 2007

Abstract
Bongaarts and Feeney have recently proposed an adjusted total fertility rate to disentangle tempo effects from changes in the quantum of fertility. We propose an extension to the Bongaarts and Feeney formula that includes variance effects: that is, changes in the variance of the fertility schedule over time. If these variance effects are ignored, the mean age at birth and the adjusted total fertility rate are biased. We provide approximations for these biases, and we extend the TFR adjustment to fertility schedules with changing variance. We apply our method to the Swedish baby boom and bust, and show that variance effects are important for evaluating the relative contributions of tempo and quantum effects to the fertility change from 1985 to 1995.
The density of social networks and fertility decisions: Evidence from South Nyanza district, Kenya
Authors: Kohler Hans-Peter , Behrman Jere R. , Watkins Susan C. 
Published: February 2007

Abstract
Demographers have argued increasingly that social interaction is an important mechanism for understanding fertility behavior. Yet it is still quite uncertain whether social learning or social influence is the dominant mechanism through which social networks affect individuals’ contraceptive decisions. In this paper we argue that these mechanisms can be distinguished by analyzing the density of the social network and its interaction with the proportion of contraceptive users among network partners. Our analyses indicate that social learning is most relevant with high market activity; in regions with only modest market activity, however, social influence is the dominant means by which social networks affect women’s contraceptive use.
Racial intermarriage pairings
Authors: Fu Vincent Kang 
Published: February 2007

AbstractMost studies of racial intermarriage rely on the prevalence of intermarriage to measure the strength of group boundaries, without scrutinizing the nature of intermarriage pairings. Examination of intermarried couples’ characteristics reveals (1) that intermarriages and endogamous marriages follow different patterns, and (2) that intermarriage pairings for some groups reflect a generalized racial status hierarchy. According to evidence from the 1990 U.S. Census PUMS, patterns in blacks’ and Mexican Americans’ marriages with whites suggest that a generalized racial status hierarchy disadvantages members of these minority groups. For marriages between Japanese Americans and whites, however, crossing the group boundary does not affect couples’ characteristics.
A cross-national comparison of the impact of family migration on women’s employment status
Authors: Boyle Paul , Cooke Thomas J. , Halfacree Keith , Smith Darren 
Published: February 2007

Abstract
In this paper we consider the effects of family migration on women’s employment status, using census microdata from Great Britain and the United States. We test a simple hypothesis that families tend to move long distances in favor of the male’s career and that this can have a detrimental effect on women’s employment status. Unlike many previous studies of this question, our work emphasizes the importance of identifying couples that have migrated together, rather than simply comparing long-distance (fe)male migrants with nonmigrant (fe)males individually. We demonstrate that women’s employment status is harmed by family migration; the results we present are surprisingly consistent for Great Britain and the United States, despite differing economic situations and cultural norms regarding gender and migration. We also demonstrate that studies that fail to identify linked migrant couples are likely to underestimate the negative effects of family migration on women’s employment status.
Women’s health and pregnancy outcomes: Do services make a difference?
Authors: Frankenberg Elizabeth , Thomas Duncan 
Published: February 2007

Abstract
We use data from the Indonesia Family Life Survey to investigate the impact of a major expansion in access to midwifery services on health and pregnancy outcomes for women of reproductive age. Between 1990 and 1998 Indonesia trained some 50,000 midwives. Between 1993 and 1997 these midwives tended to be placed in relatively poor communities that were relatively distant from health centers. We show that additions of village midwives to communities between 1993 and 1997 are associated with a significant increase in body mass index in 1997 relative to 1993 for women of reproductive age, but not for men or for older women. The presence of a village midwife during pregnancy is also associated with increased birthweight. Both results are robust to the inclusion of community-level fixed effects, a strategy that addresses many of the concerns about biases because of nonrandom program placement.
Black-White Unions: West Indians and African Americans compared
Authors: Model Suzanne , Fisher Gene 
Published: February 2007

AbstractIn this research we use 1990 PUMS data to compare the propensity for unions between African Americans and native whites with the propensity for unions between British West Indians and native whites. In addition, we distinguish women and men. Descriptive statistics indicate that West Indians, with the exception of men who arrived as adults, are more likely than African Americans to have white partners. After the introduction of controls for several correlates of intermarriage, however, West Indian men of any generation have lower exogamy rates than African American men, while exogamy rates are higher among West Indian women who arrived as children or who were born in the United States than among African American women. Thus we find no consistent evidence of greater exogamy for British West Indians than for African Americans.
Long-Run convergence of ethnic skill differentials, revisited
Authors: Borjas George J. 
Published: February 2007

Abstract
In my original study, “Long-Run Convergence of Ethnic Skill Differentials,” I concluded that the ethnic differentials introduced by the Great Migration seemed to persist into the second and third generations. Alba, Lutz, and Vesselinov argue that my study contained a number of conceptual and data problems, and conclude that the correlation between the skills of the first and the third generations disappears when these problems are taken into account. My reanalysis of the Alba et al. data, however, documents a stronger link between the skills of the first and the third generations than suggested by those authors.
Sibling, peer, neighbor, and schoolmate correlations as indicators of the importance of context for adolescent development
Authors: Duncan Greg J. , Boisjoly Johanne , Mullan Harris Kathleen 
Published: February 2007

AbstractWe use nationally representative data to calculate correlations in achievement and delinquency between genetically differentiated siblings within a family, between peers as defined by adolescents’ “best friend” nominations, between schoolmates living in the same neighborhood, and between grademates within a school. We find the largest correlations between siblings, especially identical twins. Grademate and neighbor correlations are small. Peer-based correlations are considerably larger than grademate and neighbor correlations but not larger than most sibling correlations. The data suggest that family-based factors are several times more powerful than neighborhood and school contexts in affecting adolescents’ achievement and behavior.
Immigrants’ welfare use and opportunity for contact with co-ethnics
Authors: Hao Lingxin , Kawano Yukio 
Published: February 2007

AbstractIn this article we examine the relationship between immigrants’ welfare use and their social capital, using the 1990 census. We measure community social capital using contact with co-ethnics and coethnics’ economic inactivity, and examine the use of AFDC and SSI in two subpopulations: single-mother families and elderly units. Major findings are that the effects of social capital differ between immigrant single-mother families and elderly units; the effects of social capital differ between the young-at-arrival elderly and the old-at-arrival elderly; and the process of AFDC use is similar for immigrants and for natives, whereas the process of SSI use is more complicated for immigrants than for natives.
Immigration and males’ earnings inequality in the regions of the United States
Authors: Reed Deborah 
Published: February 2007

Abstract
In this paper I investigate the impact of recent immigration on males’ earnings distributions in the major regions of the United States. I use six counterfactual scenarios to describe alternative regional skill distributions and wage structures for the population of natives and long-term immigrants in the absence of recent immigration. I find that immigration over the last three decades can account for a substantial portion of the variation in inequality across the regions. Recent immigration has contributed moderately to national growth in males’ earnings inequality, primarily by changing the composition of the population.
Differences in the locational attainment of immigrant and native-born households with children in New York City
Authors: Rosenbaum Emily , Friedman Samantha 
Published: February 2007

Abstract
In this paper we use a data set created especially for New York City to evaluate whether the locational attainment of households with children, as indicated by the context of the neighborhoods in which they live, varies by their immigrant status. In addition, we evaluate whether the relationship between immigrant status and neighborhood conditions varies by the householder’s race/ethnicity. Overall, when compared with native-born households with children, immigrant households with children live in neighborhoods of lower quality, characterized by higher teenage fertility rates and higher percentages of students in local schools scoring below grade level in math and of persons receiving AFDC, but lower rates of juvenile detention. Further analyses, however, revealed that race/ethnicity is far more potent than immigrant status per se in predicting where households with children live.
Is breast-feeding a substitute for contraception in family planning?
Authors: Rous Jeffrey J. 
Published: February 2007

AbstractUsing data from the Cebu Longitudinal Health and Nutrition Survey, I disentangle the complex interrelationship between breastfeeding, postpartum amenorrhea, and choice of contraceptive method. I find evidence that women substitute breast-feeding for contraception. Further, endogeneity bias, if not controlled, would cause the relationship to be slightly overstated. In addition, the results suggest that although increased education and income result in decreased breast-feeding, any effect on fertility will be offset by changes in contraceptive use.
The developmental paradigm, reading history sideways, and family change
Authors: Thornton Arland 
Published: February 2007

AbstractThe developmental paradigm, reading history sideways, and cross-cultural data have converged to exert a profound influence on social scientists and ordinary people. Through the use of these tools, social scientists of the 1700s and 1800s concluded that family patterns in northwest Europe had undergone many substantial changes before the early 1800s. These conclusions were accepted until the last several decades of the 1900s, when almost all were seriously challenged; many were declared to be myths. Further, the developmental paradigm, reading history sideways, and the conclusions of generations of social scientists created a package of ideas—developmental idealism—that subsequently became a powerful influence for family change in many parts of the world during the past two centuries. This developmental idealism has been a substantial force for changing living arrangements, marriage, divorce, gender relations, intergenerational relationships, and fertility.
A dynamic analysis of the effect of child care costs on the work decisions of low-income mothers with infants
Authors: Baum Charles L. 
Published: February 2007

Abstract
Child care costs reduce the net benefit of working and consequently influence mothers’ decisions to work. They affect the employment of low-income mothers in particular because they represent a larger portion of these mothers’ earnings. I used a hazard framework to examine a mother’s decisions about work and hours of work after childbirth. I focused on low-income mothers with infants because they are the ones who may be most affected by child care costs. The results showed that child care costs are a barrier to work that is larger for low-income mothers than for non-low-income mothers. Further, child care costs have large negative effects on hours of work.
Population momentum for gradual demographic transitions: an alternative approach
Authors: Goldstein Joshua R. 
Published: February 2007

Abstract
In this article, I derive a simple formula for approximating the ultimate size of a population that undergoes a gradual transition to replacement fertility. I model the fertility transition by specifying a linear frontier on the Lexis surface across which a change in fertility is instantaneous. Gradual transitions result from variations in the slope of this frontier. This framework can be used to reproduce and understand previous studies of population momentum and gradual transitions.
Low birth weight, social factors, and developmental outcomes among children in the United States
Authors: Boardman Jason D. , Powers Daniel A. , Padilla Yolanda C. , Hummer Robert A. 
Published: February 2007

Abstract
We used six waves of the National Longitudinal Survey of Youth-Child Data (1986–1996) to assess the relative impact of adverse birth outcomes vis-à-vis social risk factors on children’s developmental outcomes. Using the Peabody Individual Achievement Tests of Mathematics and Reading Recognition as our outcome variables, we also evaluated the dynamic nature of biological and social risk factors from ages 6 to 14. We found the following: (1) birth weight is significantly related to developmental outcomes, net of important social and economic controls; (2) the effect associated with adverse birth outcomes is significantly more pronounced at very low birth weights (&lt; 1,500 grams) than at moderately low birth weights (1,500–2,499 grams); (3) whereas the relative effect of very low-birth-weight status is large, the effect of moderately low weight status, when compared with race/ethnicity and mother’s education, is small; and (4) the observed differentials between moderately low-birth-weight and normal-birth-weight children are substantially smaller among older children in comparison with younger children.
Education and fertility in sub-Saharan africa: Individual and community effects
Authors: Kravdal Øystein 
Published: February 2007

AbstractUsing data from Demographic and Health Surveys for 22 countries in sub-Saharan Africa, I show that the average educational level in a village or a community of a similar size has a significant depressing effect on a woman’s birth rates, net of urbanization and her own education. According to simulations, average fertility for these countries would be 1.00 lower if education were expanded from the current level in the region to the relatively high level in Kenya. The exclusion of aggregate education from the model leaves a response of only 0.52. A considerable aggregate contribution is estimated even when several potential determinants of education are included. This finding illustrates the need to consider aggregate education in future assessments of the total impact of education.
Stability across cohorts in divorce risk factors
Authors: Teachman Jay D. 
Published: February 2007

AbstractOver the past quarter-century, many covariates of divorce have been identified. However, the extent to which the effects of these covariates remain constant across time is not known. In this article, I examine the stability of the effects of a wide range of divorce covariates using a pooled sample of data taken from five rounds of the National Survey of Family Growth. This sample includes consistent measures of important predictors of divorce, covers marriages formed over 35 years (1950–1984), and spans substantial historical variation in the overall risk of marital dissolution. For the most part, the effects of the major sociodemographic predictors of divorce do not vary by historical period. The one exception is race. These results suggest that the effects associated with historical period have been pervasive, simultaneously altering the risk of divorce for most marriages
Nonmarital childbearing: Influences of education, marriage, and fertility
Authors: Upchurch Dawn M. , Lillard Lee A. , Panis Constantijn W. A. 
Published: February 2007

Abstract
We examined the determinants of nonmarital fertility, focusing on the effects of other life-course events: education, marriage, marital dissolution, and marital fertility. Since these determinants are potentially endogenous, we modeled the processes that generate them jointly with nonmarital fertility and accounted for the sequencing of events and the unobserved correlations across processes. The results showed that the risk of nonmarital conception increases immediately after leaving school and that the educational effects are less pronounced for black women than for other women. The risk is lower for previously married women than for never-married women, even controlling for age, but this reduction is significant only for black women. The more children a woman already has, the lower her risk of nonmarital childbearing, particularly if the earlier children were born during a previous marriage. Ignoring endogeneity issues seriously biases the estimates of several substantively important effects.
Adjusting period tempo changes with an extension of ryder’s basic translation equation
Authors: Yi Zeng , Land Kenneth C. 
Published: February 2007

Abstract
We show that the observed changes in the period tempo of fertility are biased and derive a new formula for adjusting such bias. We present illustrative applications of our proposed method to the cases of the United States and Taiwan. We then describe the relevance of adjustments of observed period fertility tempo for evaluating family planning programs aiming at delaying and reducing births to slow down population growth in developing countries. The work reported in this article also can be regarded as an extension of Ryder’s basic translation equation. The extension provides a set of formulas expressing relationships of quantum-tempo between cohorts and periods under specified assumptions.
