Midlife in the United States (MIDUS 2): Milwaukee African American Sample, 2005-2006 (ICPSR 22840)
Midlife in the United States (MIDUS 3): Milwaukee African American Sample, 2016-2017 (ICPSR 37120)
In 2005, 592 African Americans from Milwaukee were added to the MIDUS sample to examine health issues in minority populations (for more details, see Midlife in the United States (MIDUS 2): Milwaukee African American Sample [ICPSR #22840]). Respondents were interviewed in their homes using a Computer Assisted Personal Interview (CAPI) survey protocol and asked to complete and return a Self-Administered Questionnaire (SAQ). Afterwards these individuals were eligible for participation in the same research protocol as the national MIDUS 2 sample, including cognitive, daily stress, biomarker, and neuroscience projects.
With support from the National Institute on Aging, a second wave of survey data collection on the Milwaukee sample was begun in 2016. The survey consisted of a 2.5 hour CAPI interview followed by a 45-page mailed SAQ. CAPI survey data was collected for 389 individuals, realizing a 78 percent response rate, adjusted for mortality and other eligibility criteria. Data collection for this follow-up wave largely repeated baseline assessments, with additional questions in selected areas (e.g., economic recession experiences, childhood experience with race, etc.). Following successful completion of the CAPI and SAQ protocols, individuals were eligible for participation in cognitive, daily stress, biomarker, and neuroscience projects.
Midlife in the United States (MIDUS Refresher 1): Milwaukee African American Sample, 2012-2013 (ICPSR 36722)
In 2012-2013, the MIDUS Milwaukee Refresher study recruited a sample of 508 Milwaukee African American adults, aged 25 to 64, designed to replenish the Midlife Development in the United States (MIDUS 2): Milwaukee African American Sample, 2005-2006 (ICPSR 22840). This sample was also designed to increase the number of racial minorities included in the broader MIDUS study. The MIDUS Milwaukee Refresher survey employed the same assessments (demographic, psycho-social, and physical and mental health) as those assembled on the existing MIDUS sample, but with additional questions about the effect of the economic recession of 2008-09. A sample of African Americans from Milwaukee County, Wisconsin, was stratified by age, gender, and income.
Area probability sampling methods were used to identify potential respondents. Field interviewers screened households to determine if they contained any African American adults. There was additional screening to achieve an appropriate age/gender distribution in a manner similar to what was done for the original MIDUS sample (Midlife in the United States (MIDUS 1), 1995-1996 [ICPSR 2760]). Milwaukee respondents were interviewed in their homes using a 2.5-hour Computer Assisted Personal Interview (CAPI) protocol and afterwards asked to complete a self-administered questionnaire (SAQ). All measures paralleled those used in the larger MIDUS samples. In addition to successful completion of the survey, participants were asked to complete a cognitive assessment by phone. Some respondents were eligible to participate in additional MIDUS projects: daily diary assessments, biomarker assessments, and neuroscience assessments.
Midlife in the United States (MIDUS Refresher 2): Milwaukee African American Sample, 2023-2024 (ICPSR 39583)
In 2012-2013, the MIDUS Milwaukee Refresher study recruited a sample of 508 Milwaukee African American adults, aged 25 to 64, designed to replenish the original MIDUS Milwaukee 1 survey that was designed to increase the number of racial minorities in 2005. The MIDUS Milwaukee Refresher survey employed the same comprehensive assessments (demographic, psycho-social, and physical and mental health) as those on the existing MIDUS sample, with additional questions about the effect of the Great Recession in 2008-09.
In 2023-2024, the second wave of survey data was collected from 327 longitudinal Refresher Milwaukee participants, including the questions (1) repeated from the Refresher 1, (2) new impacts of the COVID-19 pandemic replacing the questions related to the Great Recession in the Refresher 1, and (3) the additional questions in selected areas (e.g., AD8, IADL, family history of dementia). This new longitudinal MIDUS Refresher Milwaukee data allow examination of period effects on health and well-being related to the COVID-19 pandemic by comparing the pre-pandemic MIDUS Refresher Milwaukee 1 data with the post-pandemic MIDUS Refresher Milwaukee 2 data. Further, the longitudinal MIDUS Refresher datasets (wave 1 and wave 2) allow investigation of the two major macro-level historic events, the Great Recession and the COVID-19 pandemic, on health and well-being.
Midlife in the United States: Refresher Sample Mortality Data, 2012-2023 (ICPSR 38024)
In 2011-2014, the MIDUS recruited a national probability sample of 3,577 adults, aged 25 to 74, designed to replenish the original MIDUS 1 (M1) baseline cohort and paralleling the five decadal age groups of the M1 baseline survey (ICPSR 2760).
The MIDUS Refresher (MR1) survey included the same comprehensive assessments as those assembled on the original MIDUS Core sample (obtained via interview and self-administered questionnaire), but with additional questions about the effect of the economic recession of 2008-09.
In 2012-2013, the National MIDUS Refresher sample was augmented with a sample of 508 Milwaukee African American adults, aged 25 to 64. This sample was designed to increase the number of racial minorities included in the MIDUS study. The MIDUS Milwaukee Refresher survey also included the same assessments as those in the Milwaukee Core sample (ICPSR 22840) and employed a personal interview. This dataset includes all known decedents from the National (ICPSR 36532) and Milwaukee (ICPSR 36722) Refresher samples, and is current for NDI records through December, 2023.

Wisconsin Longitudinal Study, 1957-2022 (ICPSR 6163)
The Wisconsin Longitudinal Study (WLS) is a long-term study of a random sample of 10,317 men and women who graduated from Wisconsin high schools in 1957. The WLS provides an opportunity to study the life course, intergenerational transfers and relationships, family functioning, physical and mental health and well-being, and morbidity and mortality from late adolescence through 2025. WLS data also cover social background, youthful aspirations, schooling, military service, labor market experiences, family characteristics and events, social participation, psychological characteristics and retirement.
Survey data were collected from the original respondents (the graduates) in 1957, 1964, 1975, 1992, 2004, 2011, 2020 and 2022; from their parents in 1957 and 1964; from a selected sibling in 1977, 1994, 2005, 2011, 2020 and 2022; from the spouse of the original respondent in 2004; and from the spouse of the selected sibling in 2006.
The collection of cognitive function data among graduates and siblings under the ILIAD study (MPIS: Sanjay Asthana, Michal Engelman, and Pamela Herd) began in 2020 to measure risk and resilience of Alzheimer's disease and related dementia (ADRD) as the cohort reaches their 80s. Data from 2020 and 2022 have been released, and 2025 and 2027 wave releases are forthcoming.
The WLS also has extensive administrative linkages, including with the 1940 and 1950 census, Social Security records, voting participation, and Medicare claims data.
