Cognitively impaired adults without a partner are highly disadvantaged, as partners constitute an important source of caregiving and emotional support. With the application of innovative multistate models to the Health and Retirement Study, this paper is the first to estimate joint expectancies of cognitive and partnership status at age 50 by sex, race/ethnicity, and education in the United States. We find that women live a decade longer unpartnered than men. Women are also disadvantaged as they experience three more years as both cognitively impaired and unpartnered than men. Black women live over twice as long as cognitively impaired and unpartnered compared with White women. Lower-educated men and women live around three and five years longer, respectively, as cognitively impaired and unpartnered than more highly educated men and women. This study addresses a novel facet of partnership and cognitive status dynamics and examines their variations by key socio-demographic factors. [ABSTRACT FROM AUTHOR]

This paper examines the influence of individual and household factors on an individual's propensity to emigrate from Halland, a region in south-west Sweden, to the United States during the era of mass migration in the late nineteenth century. The study has a case-control design, using individual-level longitudinal data for a group of emigrants (cases) and a group of non-emigrants (controls). Results indicate the importance of a family's emigration history; individuals whose relatives had previously moved to the United States were more likely to emigrate themselves. In addition, the results also show how this impact varied between groups and how other factors relating to the individual's life situation affected the migration decision. Thus, this paper shows how chain migration and migration networks play important roles during times of mass migration. [ABSTRACT FROM AUTHOR]

This paper introduces the metric ‘mean duration of obesity’ to measure the average number of years lived with obesity in a population. A procedure was developed to estimate duration from periodic cross-sectional surveys. For annual cohorts born in the United States between 1925 and 1989, I estimated a logit model to derive age-cohort-specific probabilities of overweight and obesity (body mass index 25 to <30 and 30, respectively), and applied life table techniques to convert these into person-years. Duration of obesity by age 50 increased fourfold from 3.58 to 14.35 years. The rate of increase was stronger across the 1945-79 and 1980-89 cohorts than the 1925-44 cohorts. The trend was driven by increased risks of obesity among children: age groups under 20 were responsible for 31 per cent of the duration increase between the 1930 and 1960 cohorts, but 72 per cent between the 1960 and 1985 cohorts.

Demographers often form estimates by combining information from two data sources—a challenging problem when one or both data sources are incomplete. A classic example entails the construction of death probabilities, which requires death counts for the subpopulations under study and corresponding base population estimates. Approaches typically entail ‘back projection', as in Wrigley and Schofield's seminal analysis of historical English data, or ‘inverse’ or ‘forward projection’ as used by Lee in his important reanalysis of that work, both published in the 1980s. Our paper shows how forward and backward approaches can be optimally combined, using a generalized method of moments (GMM) framework. We apply the method to the estimation of death probabilities for relatively small subpopulations within the United States (men born 1930–39 by state of birth by birth cohort by race), combining data from vital statistics records and census samples.

Increased border enforcement efforts have redistributed unauthorized Mexican migration to the United States (US) away from traditional points of crossing, such as San Diego and El Paso, and into more remote areas along the US–Mexico border, including southern Arizona. Yet relatively little quantitative scholarly work exists examining Mexican migrants’ crossing, apprehension, and repatriation experiences in southern Arizona. We contend that if scholars truly want to understand the experiences of unauthorized migrants in transit, such migrants should be interviewed either at the border after being removed from the US, or during their trajectories across the border, or both. This paper provides a methodological overview of the Migrant Border Crossing Study (MBCS), a unique data source on Mexican migrants who attempted an unauthorized crossing along the Sonora–Arizona border, were apprehended, and repatriated to Nogales, Sonora in 2007–09. We also discuss substantive and theoretical contributions of the MBCS. [ABSTRACT FROM PUBLISHER]

Multi-racial (mixed-race) people constitute a growing percentage of the United States (US) population. The study reported in this paper used residential segregation measures as a proxy for social distance, to examine whether segregation levels of multi-racial groups differ from those of mono-racial groups in the US in 2010. First, we find that all multi-racial groups considered in the study experience lower levels of segregation at county level than their mono-racial counterparts. However, black-whites and Hispanic-whites experience higher levels of segregation than other multi-racial groups. Second, we find region and minority composition of counties are associated significantly with segregation levels for multi-racial groups, but relative income is not. [ABSTRACT FROM AUTHOR]

The paper seeks to identify common features in the fertility patterns of the English-speaking world and provide a model basis for comparison of fertility between countries and over time. Attention is focused on the heterogeneity within the fertility patterns of Australia, Canada, New Zealand, and the United States, similar to that reported earlier for the UK and the Irish Republic. The recent age-specific fertility patterns of these countries display a marked 'bulge' in fertility of women under age 25. A mixture model with two-component: Hadwiger functions provides a suitable fit. The heterogeneity thus suggested is shown to be related to differences in the timing of births by marital status, and its magnitude is related to the proportion of births outside marriage. Additionally, there is some evidence that, in the United States, and to a lesser extent in New Zealand, this heterogeneity in fertility patterns may be explained by ethnic differences in the timing and number of births.

This paper analyzes self-selection of returning immigrants. We propose an empirical model for this purpose, and apply it to Israeli-born immigrants who arrived in the United States during 1970-79 and returned to Israel during 1980-89. The results, based on analyses of the 5 per cent Public Use Microdata Samples (PUMS) of the 1980 and 1990 United States censuses, suggest that those who return from the United States to Israel have reached a higher level at school than those who remain in the United States. However, the income analysis suggests that, at each schooling level, those who returned to Israel would have been less successful in the United States labour market than Israelis of similar schooling (and other measured characteristics) who remained in the United States. These results were corroborated using Israeli census data that include information on returning Israelis. [ABSTRACT FROM AUTHOR]

This paper documents increasing cohabitation in the United States, and the implications of this trend for the family lives of children. The stability of marriage-like relationships (including marriage and cohabitation) has decreased - despite a constant divorce rate. Children increasingly live in cohabiting families either as a result of being born to cohabiting parents or of their mother's entry into a cohabiting union. The proportion of births to unmarried women born into cohabiting families increased from 29 to 39 per cent in the period 1980-84 to 1990-94, accounting for almost all of the increase in unmarried childbearing. As a consequence, about two-fifths of all children spend some time in a cohabiting family, and the greater instability of families begun by cohabitation means that children are also more likely to experience family disruption. Estimates from multi-state life tables indicate the extent to which the family lives of children are spent increasingly in cohabiting families and decreasingly in married families.
