Obesity, disease, and functional limitation in later life
Authors: Himes Christine L. 
Published: March 2007

AbstractLittle is known about the effects of obesity late in life. Using data from the Longitudinal Study of Aging and the Assets and Health Dynamics of the Oldest Old Survey, this study finds an increased prevalence of obesity, over time, among those 70 and older. Obesity is related most strongly to limitations in activities of daily living (ADLs) for women and to activities related to mobility. One ADL, eating, has a negative association to obesity. Obesity is associated with an increased prevalence of arthritis, diabetes, and hypertension. These results are cross-sectional and are based on self-reports of height and weight; they must be interpreted cautiously.
Son preference and sex composition of children: Evidence from india
Authors: Clark Shelley 
Published: March 2007

Abstract
Although the effect of son preference on sex composition of children ever born is undetectable in national-level estimates that aggregate across all families, this article provides empirical evidence from India that son preference has two pronounced and predictable family-level effects on the sex composition of children ever born. First, data from India show that smaller families have a significantly higher proportion of sons than larger families. Second, socially and economically disadvantaged couples and couples from the northern region of India not only want but also attain a higher proportion of sons, if the effects of family size are controlled.
Are births underreported in rural China? Manipulation of statistical records in response to China’s population policies
Authors: Merli M. Giovanna , Raftery Adrian E. 
Published: March 2007

Abstract
Under the current family planning policy in China, the criterion for evaluating all parties involved in the birth planning system provides an incentive for everyone to see that the policy is met, either in reality through strict enforcement of family planning regulations, or statistically through manipulation of statistical records. We investigate underreporting of births in four rural counties of northern China, using data from a 1992 sample survey featuring a reproductive history. To clarify the mechanisms of underreporting, we focus on the ways in which reporting errors may affect the distribution of first births by time since marriage. The results of our investigation suggest that in three of the four counties, first-birth intervals are lengthened by underreporting of girl babies and by replacing them with second births reported as first births.
Is there competition between breast-feeding and maternal employment?
Authors: Roe Brian , Whittington Leslie A. , Fein Sara Beck , Teisl Mario F. 
Published: March 2007

AbstractTheory suggests that the decision to return to employment after childbirth and the decision to breast-feed may be jointly determined. We estimate models of simultaneous equations for two different aspects of the relationship between maternal employment and breast-feeding using 1993-1994 data from the U.S. Food and Drug Administration’s Infant Feeding Practices Study. We first explore the simultaneous duration of breast-feeding and work leave following childbirth. We find that the duration of leave from work significantly affects the duration of breast-feeding, but the effect of breast-feeding on work leave is insignificant. We also estimate models of the daily hours of work and breast-feedings at infant ages 3 months and 6 months postpartum. At both times, the intensity of work effort significantly affects the intensity of breast-feeding, but the reverse is generally not found. Competition clearly exists between work and breast-feeding for many women in our sample.
The impact of wives’ earnings on income inequality: Issues and estimates
Authors: Cancian Maria , Reed Deborah 
Published: March 2007

Abstract
We estimate the extent to which rising family income inequality can be explained by changes in the earnings of married women. We develop a decomposition equation that separates single persons from married couples (decomposition by population group) and, for married couples, distinguishes the impact of wives ’ earnings from other sources of income (decomposition by income source). Despite the rising correlation between husbands’ and wives’ earnings, changes in wives ’ earnings do not explain a substantial portion of the increase in family income inequality. Our results contradict those of some previous analyses. The inconsistency of recent esti-mates can be traced to the use of a variety of conceptually different approaches in the previous literature. We clarify these approaches by explicitly distinguishing the conceptual issues, analyzing the empirical components, and providing comprehensive estimates.
The educational attainment of young women: Role model effects of female high school faculty
Authors: Nixon Lucia A. , Robinson Michael D. 
Published: March 2007

Abstract
To test for the presence of role model effects of female high school faculty and professional staff on young women in high school, we estimate several models of educational attainment for young women using data from the National Longitudinal Survey of Youth. Exposure to female high school faculty and professional staff has a positive impact on the educational attainment of young women. This result, combined with our finding that female faculty and professional staff have no significant impact on the educational attainment of young men, supports a female role model hypothesis.
The gender gap in the economic well-being of nonresident fathers and custodial mothers
Authors: Bianchi Suzanne M. , Subaiya Lekha , Kahn Joan R. 
Published: March 2007

Abstract
Using a unique sample of couples with children, we estimate the gender gap in economic well-being after marital separation, something that previous studies of individuals who divorce have not been able to do. The income-to-needs levels of formerly married mothers are only 56% those of their former husbands. The postseparation gender gap is reduced if the wife was employed full-time and was an above-average earner before marital disruption. The gap is also relatively small among the least economically independent wives, those who were not employed before separation. For the latter group, the husband’s relatively low income tends to reduce the gender gap.
The new labor market: Immigrants and wages after IRCA
Authors: Phillips Julie A. , Massey Douglas S. 
Published: March 2007

AbstractWe examine the effect of the Immigration Reform and Control Act (IRCA) on migrants ’ wages using data gathered in 39 Mexican communities and their U.S. destination areas. We examine changes in the determinants of wages before and after the passage of IRCA, as well as the effects of its massive legalization program. Migrants ’ wages deteriorated steadily between 1970 and 1995, but IRCA did not foment discrimination against Mexican workers per se. Rather, it appears to have encouraged greater discrimination against undocumented migrants, with employers passing the costs and risks of unauthorized hiring on to the workers. Although available data do not permit us to eliminate competing explanations entirely, limited controls suggest that the post-IRCA wage penalty against undocumented migrants did not stem from an expansion of the immigrant labor supply, an increase in the use of labor subcontracting, or a deterioration of the U.S. labor market.
The impact of war, famine, and economic decline on marital fertility in ethiopia
Authors: Lindstrom David P. , Berhanu Betemariam 
Published: March 2007

AbstractWe examine recent fertility trends in Ethiopia for evidence of short- and long-term responses to famine, political events, and economic decline. We use retrospective data on children ever born from the 1990 National Family and Fertility Survey to estimate trends in annual marital conception probabilities, controlling for women’s demographic and socioeconomic characteristics. The results of our analysis provide evidence of significant short-term declines in conception probabilities during years of famine and major political and economic upheaval. In the longer term, marital fertility in both urban and rural areas declined in the 1980s after increasing moderately in the 1970s.
Demographics of the gay and lesbian population in the United States: Evidence from available systematic data sources
Authors: Black Dan , Gates Gary , Sanders Seth , Taylor Lowell 
Published: March 2007

Abstract
This work provides an overview of standard social science data sources that now allow some systematic study of the gay and lesbian population in the United States. For each data source, we consider how sexual orientation can be defined, and we note the potential sample sizes. We give special attention to the important problem of measurement error, especially the extent to which individuals recorded as gay and lesbian are indeed recorded correctly. Our concern is that because gays and lesbians constitute a relatively small fraction of the population, modest measurement problems could lead to serious errors in inference. In examining gays and lesbians in multiple data sets we also achieve a second objective: We provide a set of statistics about this population that is relevant to several current policy debates.
Age reporting among white Americans aged 85+: Results of a record linkage study
Authors: Hill Mark E. , Preston Samuel H. , Rosenwaike Ira 
Published: March 2007

Abstract
This study investigates age reporting on the death certificates of older white Americans. We link a sample of death certificates for native-born whites aged 85+ in 1985 to Social Security Administration records and to records of the U.S. censuses of 1900, 1910, and 1920. When ages in these sources are compared, inconsistencies are found to be minimal, even beyond age 95. Results show little distortion and no systematic biases in the reported age distribution of deaths. To explore the effect of age misreporting on old-age mortality, we estimate “corrected” age-specific death rates by the extinct-generation method for the U.S. white cohort born in 1885. With few exceptions, corrected and uncorrected rates in single years differ by less than 3% and are not systematically biased. When we compare corrected rates with those for the same birth cohort in France, Japan, and Sweden, we find that white American mortality at older ages is exceptionally low.
Regional analysis of divorce in China since 1980
Authors: Yi Zeng , Deqing Wu 
Published: March 2007

AbstractThis paper estimates and discusses divorce measures in China and its 30 provinces since 1980. The propensity for divorce in China increased 42% between 1982 and 1990. Substantial increases in divorce were observed in all provinces except Xinjiang and Shanxi. We found a fairly strong regional pattern of divorce in China: Divorce rates were lowest on the east coast and in eastern areas, highest in the northwest and the northeast, and moderate in the middle and southern parts of the country. Descriptive explanations of trends and regional variations are presented.
Social security, economic growth, and the rise in elderly widows’ independence in the twentieth century
Authors: McGarry Kathleen , Schoeni Robert F. 
Published: March 2007

Abstract
The percentage of elderly widows living alone rose from 18% in 1940 to 62% in 1990, while the percentage living with adult children declined from 59% to 20%. This study finds that income growth, particularly increased Social Security benefits, was the single most important determinant of living arrangements, accounting for nearly one-half of the increase in independent living. Unlike researchers in earlier studies, we find no evidence that the effect of income became stronger over the period. Changes in age, race, immigrant status, schooling, and completed fertility explain a relatively small share of the changes in living arrangements.
How does POSSLQ measure up? Historical estimates of cohabitation
Authors: Casper Lynne M. , Cohen Philip N. 
Published: March 2007

Abstract
We use March Current Population Survey (CPS) data from 1977 to 1997 to produce a new historical series of indirect cohabitation prevalence estimates. We compare our new estimates with those produced by the traditional method and evaluate the new estimates. We then compare the indirect estimates with the new direct estimates to investigate whether biases exist in the indirect estimates. Our findings indicate that the traditional indirect method of estimating cohabitation prevalence underestimates cohabitors in different subpopulations, especially among those with children. We also find that the new indirect measure produces relatively unbiased estimates of cohabitors’ characteristics.
Commentary on “A methodology for identifying married couples in medicare data”
Authors: Kestenbaum Bert 
Published: March 2007

Abstract
Authors of an article appearing recently in Demography propose a retrospective method to identify husband-wife pairs in administrative records. Although their premise is correct, they overstate the power of their methodology. The error stems from a misunderstanding of how persons entitled to both primary and secondary social security benefits are classified in program data. A retrospective look four years after the reference date shows that the number of pairs is increased by less than 10%, not by more than 50%, as the authors claim.
Reexamining the link of early childbearing to Marriage and to subsequent fertillty
Authors: Philip Morgan S. , Rindfuss Ronald R. 
Published: March 2007

Abstract
Using data from the 1980, 1985, and 1990 Current Population Surveys, we show that the link between early fertility and nonmarital births has become stronger. Women who give birth earlier are increasingly likely to be unmarried. In contrast, we find a weaker association between first births at young (versus older) ages and (1) a rapid pace of subsequent childbearing and (2) higher completed fertility. We discuss possible causes and consequences of these changes.
Incomplete reporting of men’s fertility in the united states and britain: A research note
Authors: Rendall Michael S. , Clarke Lynda , Peters H. Elizabeth , Ranjit Nalini , Verropoulou Georgia 
Published: March 2007

Abstract
We evaluate men;s retrospective fertility histories from the British Household Panel Survey and the U.S. Panel Study of Income Dynamics (PSID). Further, we analyze the PSID men’s panel-updated fertility histories for their possible superiority over retrospective collection. One third to one half of men’s nonmarital births and births within previous marriages are missed in estimates from retrospective histories. Differential survey underrepresentation of previously married men compared with previously married women accounts for a substantial proportion of the deficits in previous-marriage fertility. More recent retrospective histories and panel-updated fertility histories improve reporting completeness, primarily by reducing the proportion of marital births from unions that are no longer intact at the survey date.
Three strikes and you're out: Demographic analysis of mandatory prison sentencing
Authors: Schmertmann Carl P. , Amankwaa Adansi A. , Long Robert D. 
Published: March 2007

Abstract
Much of the debate about the costs and benefits of “three-strikes” laws for repeat felony offenders is implicitly demographic, relying on unexamined assumptions about prison population dynamics. However, even state-of-the-art analysis has omitted important demographic details. We construct a multistate life-table model of population flows to and from prisons, incorporating age-specific transition rates estimated from administrative data from Florida. We use the multistate life-table model to investigate patterns of prison population growth and aging under many variants of three-strikes laws. Our analysis allows us to quantify these demographic changes and suggests that the aging of prison populations under three-strikes policies will Significantly undermine their long-run effectiveness.
The past, present, and future of sex segregation methodoloqy
Authors: Grusky David B. , Charles Maria 
Published: March 2007

Abstract
We review the logic underlying margin-free analyses of sex segregation arrays. In the course of our review, we show that the Karmel-MacLachlan decomposition does not live up to its margin-free billing, as the index upon which it rests, Ip, is itself margin-sensitive. Moreover, because the implicit individualism of D is necessarily inconsistent with margin-free analysis, the field would do well to abandon not merely the Karmel-MacLachlan decomposition but all related efforts to purge marginal dependencies from D-inspired measures. The criticisms that Watts (1998) levels against our log-multiplicative approach are likewise unconvincing. We demonstrate that our preferred models pass the test of organizational equivalence, that the “problem⤎ of zero cells can be solved by applying well-developed methods for ransacking incomplete or sparse tables, and that simple log-multiplicative models can be readily devised to analyze disaggregate arrays. We illustrate these conclusions by analyzing a new cross-national archive of detailed segregation data.
The analysis of sex segregation: When is index measurement not index measurement?
Authors: Watts Martin 
Published: March 2007

Abstract
In their paper in this issue. Grusky and Charles (1998) make a number of dubious claims about the measurement and interpretation of sex segregation. First, they incorrectly claim that only log-odds measures yield margin-free measures of segregation. Second. the estimation and testing of a limited class of log-linear models does not provide an independent test of the appropriateness of a log-odds ratio index to measure segregation. Their estimation informs them of the statistically justifiable degree of occupational disaggregation, not whether a log-odds ratio is superior to, say, a linear index in the measurement of segregation. Finally, their index A is beset with problems of interpretation. not withstanding their arguments. and their additional measures, Aw and AB, suffer similar problems. Grusky and Charles are. however, correct in arguing that measurement procedures should be margin-free. Further, I concur with the view that the adoption of a single annual summary measure of segregation cannot be justified. because it is premised on the assumption that individual occupations, or groups of occupations. exhibit similar trends in sex segregation.
Reconstructing the size of the African American population by age and sex, 1930–1990
Authors: Preston Samuel H. , Elo Irma T. , Foster Andrew , Fu Haishan 
Published: March 2007

Abstract
We estimate the size of the African American population in five-year age groups at census dates from 1930 to 1990 using a three-part strategy. For cohorts born after 1935, we follow the U.S. Census Bureau in using classical demographic analysis. To estimate the size of cohorts born before 1895, we use extinct-generation estimates. For remaining cohorts, we implement an age/period/cohort model of census counts. All approaches are applied to a data set in which the age distribution of deaths has been corrected for age misreporting. Results provide strong confirmation of the basic validity of Census Bureau estimates of census undercounts for African Americans while extending estimates to new cohorts and periods. Our estimates are less consistent with an historical series prepared by Coale and Rives (1973).
Changes in racial identification and the educational attainment of American Indians, 1970–1990
Authors: Eschbach Karl , Supple Khalil , Snipp C. Matthew 
Published: March 2007

AbstractWe use data from the 1970, 1980, and 1990 census public-use files to assess the impact of newly identified Indians on the educational attainment of American Indians who were at least 25 years old in 1970. We test the hypotheses that this impact was limited to metropolitan areas and to states with small Indian populations. We find that educational attainment for American Indians rose sharply between 1970 and 1990 and that changes in racial identification were an important component of this increase in 1980 but not in 1990. Increases in educational attainment were concentrated in metropolitan areas and occurred in states with large and small Indian populations.
Intergenerational relations in urban China: Proximity, contact, and help to parents
Authors: Bian Fuqin , Logan John R. , Bian Yanjie 
Published: March 2007

AbstractAlthough most older Chinese parents live with an adult son or daughter, most adult offspring do not live with parents. We examine the relations of these noncoresident offspring with parents in terms of proximity, frequency of contact, and exchange of help. Based on a 1993 random sample survey conducted in two major Chinese cities, we find that although rates of coresidence are high, noncoresident sons and daughters live close to parents, have frequent contact with their parents, and provide regular help to parents. Relationships with noncoresident sons and daughters are unaffected by whether parents coreside with another child. There is some evidence of closer relationships with sons than with daughters, but parents without a son receive as much help from all children as do parents with sons. The effects of these and other predictors are estimated in multivariate analyses, and results are interpreted in terms of the persistence or change of traditional family norms.
Trends in single mothers’ living arrangements from 1970 to 1995: Correcting the Current Population Survey
Authors: London Rebecca A. 
Published: March 2007

Abstract
I examine trends in single mothers’ living arrangements using data from the 1970–1995 Current Population Surveys. I create a consistent trend by correcting a coding problem that stemmed from the misidentification of children living in multigenerational households before 1984. Revised estimates show that the number of single mothers in each of these years was undercounted by 200,000–300,000. All of these women were subfamily heads living with their parents, and the problem occurred disproportionately among teens and black women. The uncorrected trend falsely indicates a large increase in the share of single mothers living with their parents. In reality, there was little change in the percentage of single mothers living in this arrangement over the time period. However, the data indicate a large increase in the rate of cohabitation and a comparable decline in the rate of living independently among this population.
Beyond single mothers: Cohabitation and marriage in the AFDC program
Authors: Moffitt Robert A. , Reville Robert , Winkler Anne E. 
Published: March 2007

Abstract
We investigate the extent and implications of cohabitation and marriage among U.S. welfare recipients. An analysis of four data sets (the Current Population Survey, the National Survey of Families and Households, the Panel Study of Income Dynamics, and the National Longitudinal Survey of Youth) shows significant numbers of cohabitors among recipients of AFDC. An even more surprising finding is the large number of married women on welfare. We also report the results of a telephone survey of state AFDC agencies conducted to determine state rules governing cohabitation and marriage. The survey results indicate that, in a number of respects, AFDC rules encourage cohabitation. Finally, we conduct an analysis of the impact of AFDC rules on cohabitation, marriage, and single motherhood and find weak evidence in support of incentives to cohabit.
