Marital Histories and Late-Life Economic Security: Do Social Security Benefits Rules Perpetuate Disparities?

Disparities in late-life economic security persist along the lines of gender, marital status, race, and educational attainment. We propose that these disparities are partly due to the fact that Social Security benefits are structured such that never-married, divorced, and cohabiting persons, those who were widowed prematurely, or were in a dual-earner couple face benefit penalties. Drawing on data from the Wisconsin Longitudinal Study (WLS), a study that has followed men and women from age 18 (in 1957) through age 72 (in 2011), we examine disparities in Social Security earnings and poverty risk on the basis of gender and marital histories. Our results reveal a large disadvantage for divorced and never-married persons (relative to their married counterparts), with women and those divorced two or more times experiencing the largest toll. We discuss the implications of our results for revamping Social Security to better meet the needs of 21st century families.

How to Access and Use Data From the Wisconsin Longitudinal Study

With over 27,000 analysis variables covering more than 60 years of participants’ lives, the WLS data can be overwhelming to new users who are looking for the measures they need to answer their research questions. Core WLS survey data is free and easy to download from our website. As we add new types of measures and new waves of data, we refine our data sharing methods to balance our need to make the data easily available with the need to protect the confidentiality of participants. This presentation will teach users how to access to the data files they need for their research and how to use our online documentation of survey instruments and data files. Symposium attendees will also receive a USB drive with the publicly available data and complete documentation.

The Wisconsin Longitudinal Study: New Cognitive, Genetic, Biological, and Social Data and a Diversifying Sample

The Wisconsin Longitudinal Study (WLS) has followed a sample of one in three Wisconsin high school graduates from the class of 1957 for over 64 years, making it an excellent data source for researchers interested in linking early and midlife characteristics to a wide range of later-life outcomes. The WLS is unique among major studies of aging cohorts for its duration of follow up, the inclusion of siblings, and the combination of rich social and health information. This symposium will provide an overview of the WLS, describe recent data collection and linkages, and introduce ongoing efforts to diversify the educational and racial/ethnic composition of the study sample. WLS data cover nearly every aspect of the participants’ lives from early life socioeconomic background, schooling, family, and work, to physical and mental health, social participation, civic engagement, well-being, and cognition. The study is linked to administrative data including Medicare records, Social Security records, mortality records, and resource data on primary and secondary schools attended by participants as well as characteristics of their employers, industries, and communities of residence. Recent data collection efforts have generated a wealth of new biological and cognitive information, including genetic data collected from saliva and blood samples, measures of the gut microbiome, and derived polygenic scores for educational attainment, cognitive performance, depression, and subjective well-being. The currently-fielding ILIAD effort is implementing rigorous AD diagnostic protocols to track the progression of dementia across cognitive phenotypes. The symposium will conclude with practical information on accessing and using the data.

Union Formation Expectations Among Older Adults Who Live Apart Together in the USA

There is an ongoing debate over whether living apart together (LAT) relationships are simply long-term relationships or alternatives to cohabitation or marriage. This study examined cohabitation and marriage expectations among older adults who LAT in the United States to address the debate. The analyses also compared the marriage expectations of older adults who LAT and cohabitors. Using data from the 2011 Wisconsin Longitudinal Study (WLS), we examined the union expectations of 250 individuals who LAT and 234 cohabitors. After providing a demographic portrait of older adults who LAT, we used ordered logistic regression models to predict their cohabitation and marriage expectations. Additional models predicted marriage expectations for older adults who LAT versus cohabitors. Older adults who LAT were unlikely to expect to formalize their unions. Adults who LAT were less likely to expect marriage than cohabitors. LAT relationships appear to be long-term partnerships in the United States.

Empty Nest Status, Marital Closeness, and Perceived Health: Testing Couples’ Direct and Moderated Associations with an Actor–Partner Interdependence Model

Building on previous examinations of marital outcomes in the empty nest phase that have been based on surveys of individuals (primarily wives), the current study examined the direct effect of no longer living with children in the home (vs. continuing to live with children) on husbands’ and wives’ ratings of marital closeness as well as their perceived health. The study also tested whether couples’ empty nest status moderated the associations between spouses’ marital closeness and health. Analyses were based on 3,765 mixed-sex couples drawn from the Wisconsin Longitudinal Study. Dyadic multilevel modeling and actor–partner interdependence models were used to test hypotheses. Results indicated that, accounting for known covariates, being in the empty nest was directly linked with both husbands and wives reporting higher levels of marital closeness and with wives (only) reporting better health. Moderating findings were less consistent, with the single reliable moderation result indicating that wives’ perceived health was improved at higher levels of their husbands’ marital closeness only among couples who were still living with children in the home. Clinical implications and future research directions are discussed.

Does Rural Living in Early Life Increase the Risk for Reduced Cognitive Functioning in Later Life?

Background: There is a robust consensus, most recently articulated in the 2020 Lancet Commission, that the roots of dementia can be traced to early life, and that the path to prevention may start there as well. Indeed, a growing body of research demonstrates that early life disadvantage may influence the risk for later life dementia and cognitive decline. A still understudied risk, however, is early life rural residence, a plausible pathway given related economic and educational disadvantages, as well as associations between later life rural living and lower levels of cognitive functioning. Objective: We aim to examine whether living in rural environments during early life has long term implications for cognitive health in later life. Methods: We employed the Wisconsin Longitudinal Study, which tracked 1 in every 3 high school graduates from the class of 1957, from infancy to ∼age 72. The data include a rich array of prospectively collected early life data, unique among existing studies, as well as later life measures of cognitive functioning. Results: We found a robust relationship between early life rural residence, especially living on a farm, and long-term risk for reduced cognitive performance on recall and fluency tasks. Controls for adolescent cognitive functioning, APOE ɛ2 and APOE ɛ4, as well as childhood and adult factors, ranging from early life socioeconomic conditions to later life health and rural and farm residency, did not alter the findings. Conclusion: Rural living in early life is an independent risk for lower levels of cognitive functioning in later life.

Assessing Dementia Prevalence in the Wisconsin Longitudinal Study: Cohort Profile, Protocol, and Preliminary Findings

Background: There is growing consensus that non-genetic determinants of dementia can be linked to various risk- and resiliency-enhancing factors accumulating throughout the lifespan, including socioeconomic conditions, early life experiences, educational attainment, lifestyle behaviors, and physical/mental health. Yet, the causal impact of these diverse factors on dementia risk remain poorly understood due to few longitudinal studies prospectively characterizing these influences across the lifespan. Objective: The Initial Lifespan’s Impact on Alzheimer’s Disease and Related Dementia (ILIAD) study aims to characterize dementia prevalence in the Wisconsin Longitudinal Study (WLS), a 60-year longitudinal study documenting life course trajectories of educational, family, occupational, psychological, cognitive, and health measures. Methods: Participants are surveyed using the modified Telephone Interview for Cognitive Status (TICS-m) to identify dementia risk. Those scoring below cutoff undergo home-based neuropsychological, physical/neurological, and functional assessments. Dementia diagnosis is determined by consensus panel and merged with existing WLS data for combined analysis. Results: Preliminary findings demonstrate the initial success of the ILIAD protocol in detecting dementia prevalence in the WLS. Increasing age, hearing issues, lower IQ, male sex, APOE4 positivity, and a steeper annualized rate of memory decline assessed in the prior two study waves, all increased likelihood of falling below the TICS-m cutoff for dementia risk. TICS-m scores significantly correlated with standard neuropsychological performance and functional outcomes. Conclusion: We provide an overview of the WLS study, describe existing key lifespan variables relevant to studies of dementia and cognitive aging, detail the current WLS-ILIAD study protocol, and provide a first glimpse of preliminary study findings.

Social Participation across Mid- and Later-life: Evidence from a Longitudinal Cohort Study

Despite the benefits of social participation for individuals and communities, little is known about how social participation varies over the life course. Drawing upon data collected between 1957 and 2011 by the Wisconsin Longitudinal Study (22,023 observations from a cohort of 6,627), this study provides four valuable results. First, I find evidence of five distinct social participation trajectories; the majority of which demonstrate social disengagement as individuals age. Second, these decreases were primarily attributable to declines in meeting friends and group exercise. Third, the activities most likely to predict being a part of more-desirable trajectories were cultural event attendance, voluntary group membership, and joining charity groups. Last, I find that seven different types of high school activities were each associated with greater social activity counts, decades later. In total, these results highlight systematic differences in social participation trajectories and suggest that age-graded participation changes are highly dependent on the underlying social activities.
