A mixture model for duration data: Analysis of second births in China
Authors: Li Lei , Choe Minja Kim 
Published: March 2007

Abstract
In this paper we introduce a mixture model in which we combine logistic regression and piecewise proportional hazards models for analysis of duration data. The model allows simultaneous estimation of two sets of effects of covariates: one of the probability of an event and the other of the timing of the event. We illustrate the application of the model through an analysis of the effects of women s characteristics and of the acceptance of a one-child certificate on the birth of second children in China. Both factors affect the probability of having a second child, but only the acceptance of a one-child certificate has a significant and strong effect on the second-birth interval.
The number of Israeli immigrants in the United States in 1990
Authors: Cohen Yinon , Haberfeld Yitchak 
Published: March 2007

Abstract
In this paper we estimate the size of several categories of “Israeli” immigrants in the United States. According to the 1990 U.S. census, there were about 95,000 Israeli-born immigrants in the United States in that year. Using the language and ancestry information available in the Public Use Microdata Sample (PUMS) of the 1990 census, we estimate that of this total, about 80,000 are Jews and 15,000 are Palestinian Arabs born in Israel. In addition to the Israeli-born, we present a range for the number of Jewish immigrants from Israel who are not Israeli-born (about 30,000–56,000). Thus our estimate for the total number of Jewish immigrants from Israel in the United States in 1990 is between 110,000 and 135,000. Fertility information available in the PUMS, also enable us to provide estimates for the number of second-generation Israelis in the United States in the 1990 (about 42,000). Finally, using both the 1980 and 1990 PUMS, we provide estimates for the rate of return migration among Israeli-born Jewish immigrants in the United States.
Changing patterns of Internal Migration 1970–1990: A comparative analysis of jews and whites in The United States
Authors: Rebhun Uzi 
Published: March 2007

Abstract
Independently conducted yet complementary sets of data from the 1970/1971 and 1990 National Jewish Population Surveys and the U.S. censuses of the same changes in the internal migration of Jews and whites during the periods 1965–1970(1971) and 1985–1990. Interstate lifetime and five-year migration rates among Jews increased to levels significantly surpassing those of whites. Adjusting Jewish migration rates for the educational achievement of their white counterparts did not have much of an effect on lifetime migration or on the recent migration of the 1970/1971 Jewish population; however, it accounted meaningfully for the migration propensities of Jews in the period 1985–1990. These findings suggest that socioeconomic status has begun to play a larger role in promoting different migration patterns than in promoting ethnic group differences. Further, the direction of Jewish migrations followed those of whites (i.e., from the Northeast and Midwest to the South and West); and due to their higher migration rates, Jews have considerably narrowed the regional distribution differences between themselves and whites. I interpret these results as evidence of the weakening role of ethnicity in present-day America.
Measuring immigrant wage growth using matched CPS files
Authors: Duleep Harriet Orcutt , Regets Mark C. 
Published: March 2007

Abstract
Cross-sectional estimates of immigrant wage growth have painted an optimistic picture of the ability of immigrants to adapt to the U.S. labor market: Studies using cross-sectional data have generally found the wage growth of immigrants to exceed that of the native born. This optimistic picture of immigrant economic assimilation was challenged by the important finding that compared to earlier immigrant cohorts, recent immigrants started at much lower wages. As such, the high wage growth of immigrants relative to the native born measured in cross-sectional data may simply be the spurious result of declining immigrant earnings ability. In this paper, we match Current Population Survey samples so that the wages of individual immigrant and native-born men can be followed for one year. We find that the wage growth of immigrants does exceed that of the native born. The general finding of faster immigrant wage growth also holds when imposing the foreign-born geographic distribution upon natives, but not when imposing the native-born geographic distribution on the foreign born—a result consistent with some theories of immigrant assimilation. In each comparison, however, the actual wage growth of immigrants relative to natives is similar to the predictions of cross-sectional regressions. This similarity suggests that either there is no cohort quality bias in the cross-sectional estimates of immigrant wage growth, or that there has been a coincidental increase in immigrant wage growth as the entry wages of immigrants have fallen.
Measuring spatial focusing in a migration system
Authors: Plane David A. , Mulligan Gordon F. 
Published: March 2007

Abstract
Equality indexes used in other geographical contexts may be used to gauge the degree of spatial focusing in an entire migration system or within the gross in- and out-migration fields of specific regions. They provide useful indicators of overall shifts in the patterns of interregional migration and can help give insight into the population redistributive roles played by specific regions. Perhaps the most common equality index used to measure income distribution is the Gini coefficient, yet it appears almost never to have been applied in migration research. In this paper we set forth a variety of Gini indexes to be used for different migration analyses and illustrate their application with recent data on U.S. interstate movements. We argue that the Gini index provides some singularly useful insights that differ from those afforded by other measures more commonly found to date in the migration analyst’s toolkit.
Family dissolution, family reconstitution, and children’s educational careers: Recent evidence for Sweden
Authors: Jonsson Jan O. , Gähler Michael 
Published: March 2007

AbstractBoth longitudinal and cross-sectional analyses on a large and recent Swedish data set demonstrate that, compared to children in intact families, children who have experienced family dissolution or reconstitution show lower educational attainment at age 16. Time constraints do not seem to be an important mechanism behind the negative effect of separation. Economic deprivation affects children s attainment negatively, but downward social mobility appears to be an even more important causal mechanism: Losing the parent with the higher social position probably reduces social capital and aspirations. When we control for socioeconomic characteristics, a small net effect of separation and reconstitution remains.
Latino, Asian, and black segregation in U.S. metropolitan areas: Are multiethnic metros different*
Authors: Frey William H. , Farley Reynolds 
Published: March 2007

Abstract
This study examines 1990 residential segregation levels and 1980–1990 changes in segregation for Latinos, Asians, and blacks in U.S. metropolitan areas. It also evaluates the effect of emerging multiethnic metropolitan area contexts for these segregation patterns. While black segregation levels are still well above those for Latinos and Asians, there is some trend toward convergence over the decade. More than half of the areas increased their Latino segregation levels over the 1980s, and almost three-fourths increased their Asian segregation levels. In contrast, black segregation levels decreased in 88%ofmetropolitan areas. Multiethnic metropolitan area context is shown to be important for internal segregation dynamics. Black segregation levels are lower, and were more likely to decline in multiethnic metropolitan areas and when other minority groups grew faster than blacks. Latino segregation was also more likely to decline in such areas, and declines in both Latino and Asian segregation were greater when other minority groups were growing. These findings point up the potential for greater mixed-race and mixed-ethnicity coresidence in the neighborhoods of multiethnic metropolitan areas.
Immigration cohorts and residential overcrowding in southern California
Authors: Myers Dowell , Lee Seong Woo 
Published: March 2007

Abstract
To what degree do immigrants reduce their high rates of residential overcrowding with increasing length of residence in the United States? This question is addressed through the application of a “double cohort” method that nests birth cohorts within immigration cohorts. This method enables duration of immigration effects to be separated from aging effects as cohorts pass through life course phases, when family sizes may be growing or shrinking. The analysis finds that cohort trends differ sharply from the cross-sectional pattern observed at a single point in time. Cohorts’ growth in income is found to contribute substantially to the decline in overcrowding over time. Cohort trends among Hispanic immigrants, however, diverge from those among others, indicating much less decrease in overcrowding and even increases over certain age spans.
The influence of parents’ marital dissolutions on children’s attitudes toward family formation
Authors: Axinn William G. , Thornton Arland 
Published: March 2007

Abstract
We investigate the influence of parents’ marital dissolutions on their children’s attitudes toward several dimensions of family formation. Hypotheses focus on the role of parents’ attitudes as a mechanism linking parents’ behavior to their children’s attitudes. We test these hypotheses using intergenerational panel data that include measures of parents’ attitudes taken directly from parents and measures of children’s attitudes taken directly from children. Results demonstrate strong effects of parental divorce, remarriage, and widowhood on children’s attitudes toward premarital sex, cohabitation, marriage. childbearing, and divorce. The results also show that parents’ own attitudes link their behavior to their children’s attitudes, although substantial effects of parental behavior remain after controlling for parents’ attitudes.
Religion and fertility in the United States: New patterns
Authors: Mosher William D. , Williams Linda B. , Johnson David P. 
Published: March 2007

Abstract
In the United States, the baby boom-era pattern of high Catholic and low Protestant fertility has ended. Among non-Hispanic whites in the 1980s, Catholic total fertility rates (TFRs) were about one-quarter of a child lower than Protestant rates (1.64 vs. 1.91). Most of the Protestant-Catholic difference is related to later and less frequent marriage among Catholics. Future research on the demography of religious groups should focus on explaining the delayed marriage pattern of Catholics, the high fertility of Mormons and frequently attending Protestants, and the very low fertility of those with no religious affiliation.
Taxes and the Family: The impact of the tax exemption for dependents on marital fertility
Authors: Whittington Leslie A. 
Published: March 2007

Abstract
In this paper I use data from the Panel Study on Income Dynamics to examine the relationship between the dependent exemption feature of the United States federal income tax (an unambiguous subsidy to dependents) and the fertility behavior of married couples over the period 1979–1983. The exemption decreases the price of a child to a household, thus having a direct relationship to the timing and/or number of children observed in a family. Conditional logit results support this hypothesis by showing that the exemption has a positive and significant impact on the likelihood of having a birth during the period under study.
Age at last birth and its components
Authors: Suchindran C.M. , Koo Helen P. 
Published: March 2007

Abstract
This paper examines the ways in which the behavior of twentieth century cohorts of American women changed simultaneously in the three components of fertility that determine age at last birth—age at first birth, spacing between subsequent births, and parity progression ratios of subsequent births—to produce changes in the timing of the completion of childbearing. It decomposes changes in the mean age at last birth among cohorts and between whites and nonwhites to changes in these three components. To perform these analyses, we developed and applied a method to estimate the distributions and means of ages at first and last births, birth intervals, and parity progression ratios from age- and parity-specific fertility rates available from vital statistics data. Results show that the cohorts increased and decreased their age at first birth, birth intervals, and parity progression ratios of lower and higher birth orders in almost every possible combination so as to achieve a relatively young age at final birth.
The Determinants of the Duration of Postpartum Sexual Abstinence in West Africa: A Multilevel Analysis
Authors: Benefo Kofi D. 
Published: March 2007

Abstract
The question of how postpartum sexual abstinence responds to social change in West Africa is important because declines in the practice could increase fertility levels and worsen child and maternal health. This study uses data from the late 1970s in Cote d’Ivoire, Ghana, and Cameroon to examine effects of modernization and women’s status on the length of abstinence. The results show that modernization and female status should be associated with declines in abstinence, which could lead to an increase in fertility and deterioration in maternal and child health.
Demographic Foundations of Political Empowerment in Multiminority Cities
Authors: Clark William A. V. , Morrison Peter A. 
Published: March 2007

Abstract
As U.S. cities accommodate increasing ethnic and racial diversity, political choices may unify or divide their local populations. Those choices pull communities toward two different modes of pluralism: traditional “melting pot” assimilation or a complex mosaic of racial and ethnic assertiveness. Central to this issue is equity and empowerment, which may be accentuated by minority populations’ size, structure, and spatial concentration. We examine two potential modes of local empowerment: “dominance,” whereby each group is the majority of voters in single election districts (reinforcing separative tendencies), and “influence,” whereby a group gains “influential minority” status in several districts (reinforcing unifying tendencies).
Racial and Ethnic Differences in Birthweight: The Role of Income and Financial Assistance
Authors: Cramer James C. 
Published: March 2007

AbstractThis paper attempts to explain the differences in birthweight observed between blacks, white Anglos, Chicanos, and other racial and ethnic groups. The analysis focuses on the role of income and financial assistance from relatives and public programs. Using data from the NLS Youth Panel, I construct a causal model of birthweight containing exogenous social and demographic risk factors and intervening proximate determinants of birthweight. A substantial part of the gap in birthweight between white Anglos and other ethnic groups (especially blacks) can be explained by the unfavorable socioeconomic and demographic characteristics of the latter. On the other hand, blacks and other minorities smoke less and have other favorable proximate characteristics that depress differences in birthweight. When these proximate determinants are controlled, large ethic differences in birthweight remain unexplained by income and other sociodemographic factors.
Childhood Living Arrangements and Adult Children’s Relations with their Parents
Authors: Lye Diane N. , Klepinger Daniel H. , Hyle Patricia Davis , Nelson Anjanette 
Published: March 2007

Abstract
We examine the relationship of childhood living arrangements to adult child-parent relations. Compared with adult children raised in intact families, adult children whose parents divorced have less frequent contact with their parents and report a lower-quality relationship with their parents. We observe these negative effects for both custodial and noncustodial parents, although the effects are larger for noncustodial parents. Remarriage of the custodial parent tends to offset the the negative impacts of divorce on relations with the custodial parent and to amplify the negative impacts on relations with noncustodial parents. Further, the longer the adult child lived apart from the parent, the weaker are relations with noncustodial parents.
Sharing a Home: The Experiences of American Women and Their Parents over the Twentieth Century
Authors: Weinick Robin M. 
Published: March 2007

Abstract
Trends and determinants of daughter-parent coresidence over the twentieth century are examined by using the 1987-1988 National Survey of Families and Households. Young women from more recent birth cohorts leave their parents’ homes for the first time at earlier ages, but are more likely to make return trips home than those born earlier. Thus cohorts show remarkable consistency in the proportion of life lived in the parental home. For the 1900-1929 birth cohorts, daughters’ lifetime probability that a parent will move in with them is approximately 15%; younger cohorts show similar age-specific probabilities to date. Explanations for these trends are considered.
A Theory of the Value of Children
Authors: Friedman Debra , Hechter Michael , Kanazawa Satoshi 
Published: March 2007

AbstractThis paper uses a non-standard value assumption—uncertainty reduction—to explain parenthood. We begin by reviewing the inadequacies of normative and standard rational choice explanations of shifts in fertility behavior. Then we propose a theory of the value of children based on the uncertainty-reduction assumption. Next we generate a range of hypotheses that follow both from this assumption and from a subsidiary assumption of marital solidarity enhancement. Finally, we explore the extent to which implications based on these new ideas are supported by the relevant empirical literature.
A Multistate Model of Fecundability and Sterility
Authors: Wood James W. , Holman Darryl J. , Yashin Anatoli I. , Peterson Raymond J. , Weinstein Maxine , Chang Ming-Cheng 
Published: March 2007

AbstractThis paper develops a multistate hazards model for estimating fecundability and sterility from data on waiting times to conception. Important features of the model include separate sterile and nonsterile states, a distinction between preexisting sterility and sterility that begins after initiation of exposure, and log-normally distributed fecundability among nonsterile couples. Application of the model to data on first birth intervals from Taiwan, Sri Lanka, and the Amish shows that heterogeneity in fecundability is statistically significant at most ages, but that preexisting sterility and new sterility are unimportant before age 40. These results suggest that sterility may not be an important determinant of natural fertility until later reproductive ages.
Double Jeopardy: Interaction Effects of Marital and Poverty Status on the Risk of Mortality
Authors: Smith Ken R. , Waitzman Norman J. 
Published: March 2007

AbstractThe purpose of this paper is to examine the hypothesis that marital and poverty status interact in their effects on mortality risks beyond their main effects. This study examines the epidemiological bases for applying an additive rather than a multiplicative specification when testing for interaction between two discrete risk factors. We specifically predict that risks associated with being nonmarried and with being poor .interact to produce mortality risks that are greater than each risk acting independently. The analysis is based on men and women who were ages 25–74 during the 1971–1975 National Health and Nutrition Examination Survey I (NHANES I) and who were traced successfully in the NHANES I Epidemiologic Follow-Up Study in 1982–1984. Overall, being both poor and nonmarried places nonelderly (ages 25–64) men, but not women, at risk of mortality greater than that expected from the main effects. This study shows that for all-cause mortality, marital and poverty status interact for men but less so for women; these findings exist when interaction is assessed with either a multiplicative or an additive standard. This difference is most pronounced for poor, widowed men and (to a lesser degree) poor, divorced men. For violent/accidental deaths among men, the interaction effects are large on the basis of an additive model. Weak main and interaction effects were detected for the elderly (age 65 +).
Nativity Concentration and Internal Migration among the Foreign-Born
Authors: Kritz Mary M. , Nogle June Marie 
Published: March 2007

Abstract
Are immigrants who live in states where large numbers of their compatriots reside more or less likely to migrate than those who live in other states? Using 1980 U.S. Census data to address that question, the analysis shows that nativity concentration deters interstate migration but not migration within the same state. Residing in a state where fellow nationals live is a more important determinant of internal migration than human capital, immigration status, or a state’s unemployment rate. New York State residence in 1975 also promotes interstate migration. This research suggests that social dimensions should be taken into account in modeling internal migration of the foreign-born.
On the Measurement of Naturalization
Authors: Liang Zai 
Published: March 2007

Abstract
This paper proposes a new way of measuring naturalization, which takes into account both emigration and death. I argue that the new method corrects for underestimation and thus provides a more accurate measure of the concept. Using data from six groups of the 1973 immigrant cohort and multiple-decrement life table techniques, I estimated and compared naturalization measures derived from new and old methods. The results show that failure to control for emigration has a significant effect on the measurement of naturalization, particularly if an immigrant group has relatively high rate of emigration. Some further substantive implications of this new method are also explored.
In Search of Asian War Brides
Authors: Saenz Rogelio , Hwang Sean-Shong , Aguirre Benigno E. 
Published: March 2007

Abstract
Because of the long presence of U.S. soldiers in Asia, war-bride marriages involving servicemen and Asian women have been formed throughout the century. The literature, however, contains little empirically sound information on Asian war brides. This analysis develops a methodology to identify war brides and applies it to estimate the number of war brides from the six major Asian groups, using the national 1980 Public Use Microdata Sample. Further analysis comparing Asian war brides with other groups of Asian wives tends to support the traditional and lower socioeconomic images commonly associated with Asian war brides.
Economic opportunity in mexico and return migration from the United States
Authors: Lindstrom David P. 
Published: March 2007

AbstractI analyze the influence of the economic characteristics of origin area on trip duration for Mexican migrants in the United States. I argue that migrants from economically dynamic areas in Mexico with favorable opportunities for employment and small capital investment have a larger incentive to stay in the United States longer and to withstand the psychic costs of separation from family and friends than do migrants from economically stagnant areas in Mexico, where the productive uses of savings are severely limited. In line with this argument we should expect investment opportunities in migrants’ origin areas to be associated positively with migrants’ trip duration in the United States. To test this hypothesis I use individual- and household-level data on U.S migration experience collected in 13 Mexican communities. Evidence from parametric hazards models supports the idea that economic characteristics of origin areas influence the motivations and strategies of Mexican migrants in the United States.
