The 500 Family Study [1998-2000: United States] (ICPSR 4549)
The 500 Family Study was designed to obtain in-depth information on middle class, dual-career families living in the United States. To understand the complex dynamics of today's families and the strategies they use to balance the demands of work and family, over 500 families from 8 cities across the United States were studied. To address different issues facing parents with older and younger children, families with adolescents and families with kindergartners were included in the sample. Working mothers and fathers are now splitting their time between their responsibilities to their family, and to their respective occupations. This study of 500 families explores how work affects the lives and well-being of parents and their children.
The study's data allows researchers to explore a broad range of questions:
- How do dual-career families manage and organize their resources and time between family and work?
- How do work conditions, including characteristics of the job and workplace environment, affect the quality of relationships among household members?
- How do dual career parents manage the moral and social development and learning experiences of their children?
- How do the work-related responsibilities of working parents affect their child's moral, social, and educational development?
- What effect is consumerism and technology having on how working families direct the moral and social development of their children?
- What do parents believe is their role regarding the child-care of their children and how they should fulfill that role both in terms of time and in the allocation of economic and social resources? What are some of the resources in the community that parents use to supervise their children?
- How do families regard the "free time" of adolescents and how they allocate adolescent "free time" in maintenance of the household?
- What is the quality of relationships among family members?
To obtain a detailed picture of work and family life, mothers, fathers, and their children were asked to complete a series of instruments including surveys, in-depth interviews, and time diaries. These instruments were designed to provide information about work, marriage, child care and parental supervision, management of household tasks, time allocations, coping strategies, and psychological well-being.
The four datasets associated with this data collection are summarized below:
- The Cortisol Data contains information for a subsample of families that elected to participate in a study of psychological stress. Parents and teenagers who agreed to participate completed an additional two days of ESM data collection. The health survey that was administered reported on a variety of health and lifestyle issues that might affect cortisol (stress hormone) levels such as medication use, consumption of caffeine and alcohol, use of nicotine, timing of menstrual cycle, pregnancy, presence of chronic illness, and respondent's height and weight. Additionally, parents reported on the health of the children (teenagers and kindergartners) participating in the study.
- The Experience Sampling Method (ESM) Data contains a variety of information related to how individuals spend their time, who they spent it with, and what activities they were engaged in over the course of a typical week. Respondents wore programmed wrist watches that emitted signals (beeps) throughout the day. When possible, family members were placed on identical signaling schedules to provide information on a range of family activities. At the time of each beep, participants were asked to complete a self-report form which asked them to answer a number of open-ended questions about their location, activities, who they were with, and psychological states. Several Likert and semantic-differential scales were used to assess participants' psychological states.
- The Parent Data contains basic demographic information from respondents as well as detailed information about parents' occupation job duties, income, work schedule, benefits (e.g., medical care, flexible work schedules, and family leave), and the consequences of their jobs (e.g. long hours, job stress, having to work weekends). Additionally, the data contain information about the extent to which parents experienced work-family conflict and what changes might help with better balance of the demands of work and family (e.g., more flexible work hours, more help from spouses with household and child care responsibilities, improved child care, and after-school care arrangements). Parental attitudes toward traditional arrangements, how household tasks were actually divided among family members, and how often the family paid for services (e.g., cleaning, yard work, meal preparation) were also captured. The data also contain information about how children are socialized in families with two working parents. Topics about the frequency with which parents engaged in various activities with their children (e.g., talking, eating meals together, attending religious services), how frequently parents monitored their teenager's activities, and how often they talked with their teenager about school activities, plans for college, career plans, friendships, and peer pressure.
- The Adolescent Data contains data for sixth through twelfth graders, which focuses on family relationships and experiences, school experiences, paid work, psychological well-being and behavioral problems, and plans for the future (e.g., college, career, and marriage -- including expectations regarding spouses' sharing of responsibility for child care, cooking, chores, and paid work). To allow for comparison of parents' and adolescents' responses to similar questions, several items appear in both the adolescent and parent data. These items include the frequency with which parents and adolescents discuss school events, college and career plans, participation in religious and other activities, gender role attitudes and the division of household tasks within the family, and items measuring depression, stress, and anxiety.
Qualitative Data -- Interviews The main purpose of the interviews was to explore topics addressed in the parent and adolescent surveys in greater detail. Parent interviews were designed to examine how working parents cope with the demands of work and family life. Adolescent interviews touched on similar themes but altered questions to gauge the adolescent's perceptions of their parents work and family lives. Kindergartner interviews were brief and focused on children's after-school and child care arrangements and time spent with parents.

Chicago Community Adult Health Study, 2001-2003 (ICPSR 31142)
The Chicago Community Adult Health Study (CCAHS) consists of four interrelated components that were conducted simultaneously: (1) a survey of adult health on a probability sample of 3,105 Chicago adults, including direct physical measurements of their blood pressure and heart rate and of height, weight, waist and hip circumference, and leg length; (2) a biomedical supplement which collected blood and/or saliva samples on a subset of 661 survey respondents; (3) a community survey in which individuals described aspects of the social environment of all survey respondents' neighborhoods; and (4) a systematic social observation (SSO) of the blocks in which potential survey respondents resided, including a lost letter drop (Milgram et al. 1965) as an unobtrusive measure of neighborhood social capital/sense of responsibility to help others. The latter two extend a community survey and SSO of neighborhoods carried out by the Project on Human Development in Chicago Neighborhoods (PHDCN) in 1995. The adult health survey and the community survey were conducted jointly through face-to-face interviews with a stratified, multistage probability sample of 3,105 individuals aged 18 and over and living in the city of Chicago, with a response rate of 72 percent that is about the highest currently attainable in large urban areas. In addition, blood pressure, heart rate, and physical measurements (of height, weight, waist and hips, and leg length) were collected during the survey interview, and blood and saliva samples from 661 respondents or 60 percent of those doing the survey in the 80 "focal" neighborhood clusters (NCs). SSOs were conducted on 1,663 of the 1,672 city blocks on which each respondent lived. The CCAHS is the largest of five projects under the NIH-funded Michigan Interdisciplinary Center on Social Inequalities, Mind and Body Mind (#P50HD38986), one of five Mind-Body Centers funded by the National Institutes of Health in late 1999. This study will advance the understanding of socioeconomic and racial/ethnic disparities in health, a major priority of the Public Health Service and the National Institutes of Health.
The PI-supplied summary mentions that the study is comprised of four components. However, for the purposes of this data release there are three distinct datasets. Demographic variables include age, birth year, race, ethnicity, number of children in the household, number of children living elsewhere, number of times the respondent has been married, and relationship status, religious preference, and sex.

Eurobarometer 72.3: Public Health Attitudes, Behavior, and Prevention, October 2009 (ICPSR 32441)
The Eurobarometer series is a unique cross-national and cross-temporal survey program conducted on behalf of the European Commission. These surveys regularly monitor public opinion in the European Union (EU) member countries and consist of standard modules and special topic modules. The standard modules address attitudes towards European unification, institutions and policies, measurements for general socio-political orientations, as well as respondent and household demographics. The special topic modules address such topics as agriculture, education, natural environment and resources, public health, public safety and crime, and science and technology.
This round of Eurobarometer surveys covers the special topic of public health and includes the following major areas of focus: (1) check-up and prevention, (2) oral health, (3) alcohol habits, (4) smoking habits, (5) organ and blood donation, and (6) sport and physical activity. Questions pertain to medical tests and health exams received in the past 12 months, eating a healthy diet, exercise, visits and access to a dentist, and food and drink consumption. Other questions addressed alcohol consumption within the past 12 months, smoking status and behavior, as well as the knowledge of human organ donation and transplant, and safety of blood transfusions compared to 10 years ago.
Demographic and other background information collected includes age, gender, nationality, marital status, occupation, age when stopped full-time education, household composition, ownership of a fixed or a mobile telephone and other durable goods, difficulties in paying bills, level in society, and Internet use. In addition, country-specific data includes type and size of locality, region of residence, and language of interview (select countries).

This study was designed to determine the nature, incidence, and coincidence of forms of interpersonal conflict and resulting conflict management styles, including physical violence, in an existing nationally-representative cohort of 18 to 32 year old adults between the years 2016 to 2018. Respondent reports of conflicts involving aggressive and violent behavior were distinguished for three relationship categories: intimate partner relationships, friends/acquaintances, and relatively unknown persons/strangers.
The research design covered questions about the nature and frequency of conflicts experienced irrespective of whether the incidents ended violently; conflict management style/tendencies (remedial actions, apologies, accounts); and differences between conflicts that turn violent and those that do not. Additional questions covered include the frequency of violence during the course of disputes, including experiences with physical victimization and the perpetration of violent acts was assessed.
Also elements that facilitate conflict escalation that are deemed important theoretical constructs in research on aggression, such as adverse childhood events, low self-control, negative affect, street code attitudes, routine activities/lifestyles, agreeableness, and alcohol and drug use, in addition to demographic and other person-level variables were investigated.

The Irish Longitudinal Study on Ageing (TILDA), COVID-19 Study, 2020 (ICPSR 38681)
This catalog record includes detailed variable-level descriptions, enabling data discovery and comparison. The TILDA Series data, including studies 34315, 38681, 37105, 37106, 38670, 38674, are currently unavailable at the request of the data producer due to concerns related to EU and Irish data privacy and data sharing rules. We are working to determine the best solution to continue to share these data with the research community. Individuals interested in obtaining TILDA data access at this time should reach out to the TILDA project directly (https://tilda.tcd.ie/data/accessing-data/).
The Irish Longitudinal Study on Ageing (TILDA) collects information on all aspects of health, economic and social circumstances from adults aged 50 years and over who reside in Ireland. Waves of data collection take place every two years. TILDA provides a comprehensive and accurate picture of the characteristics, needs and contributions of older persons in Ireland to inform and support improvements in policy and practice; advancements in technology and innovation; tailored education and training through an enhanced ageing research infrastructure; harmonisation with leading international research to ensure adoption of best policy and practice and comparability of results. TILDA is necessary to act as the foundation on which we can plan appropriate health, medical, social and economic policies for our older adults.
Participants were invited to complete the COVID Self Completion Questionnaire to capture their experiences during the COVID-19 pandemic. This data collection was planned in response to the pandemic and took place during the time when Wave 6 fieldwork was originally scheduled to take place.
The TILDA COVID-19 Study covers a range of aspects of the lives of adults aged 60 years and older during the first few months of the pandemic. As well as information on changes to normal day activities due to social-distancing and other restrictions on social interactions, we examine how these alterations to peoples' lives have impacted on their physical and mental wellbeing. The study also records peoples' exposure to the virus as well as that of their families and friends.
Midlife in the United States (MIDUS 1), 1995-1996 (ICPSR 2760)
The Midlife in the United States (MIDUS) is a collaborative, interdisciplinary investigation of patterns, predictors, and consequences of midlife development in the areas of physical health, psychological well-being, and social responsibility. A description of the study and findings from it are available at http://www.midus.wisc.edu.
The first wave of the MIDUS study (MIDUS 1 or M1) collected survey data from a total of 7,108 participants. The baseline sample was comprised of individuals from four subsamples: (1) a national RDD (random digit dialing) sample (n=3,487); (2) oversamples from five metropolitan areas in the U.S. (n=757); (3) siblings of individuals from the RDD sample (n=950); and (4) a national RDD sample of twin pairs (n=1,914). All eligible participants were non-institutionalized, English-speaking adults in the coterminous United States, aged 25 to 74.
Data from the samples were collected primarily in 1995/96. The survey (Project 1) dataset contains responses from a 30-minute Phone interview and two 50-page Self-Administered Questionnaire (SAQ) instruments. Of the 7,108 respondents who completed the Phone interview, 6,325 also completed the SAQ.
This updated version of the study is comprised of three primary datasets:
Dataset 1, Main, Siblings, and Twin Data, contains responses from the main survey of 7,108 respondents. Respondents were asked to provide extensive information on their physical and mental health throughout their adult lives, and to assess the ways in which their lifestyles, including relationships and work-related demands, contributed to the conditions experienced. Those queried were asked to describe their histories of physical ailments, including heart-related conditions and cancer, as well as the treatment and/or lifestyle changes they went through as a result. A series of questions addressed alcohol, tobacco, and illegal drug use, and focused on history of use, regularity of use, attempts to quit, and how the use of those substances affected respondents' physical and mental well-being. Additional questions addressed respondents' sense of control over their health, their awareness of changes in their medical conditions, commitment to regular exercise and a healthy diet, experience with menopause, the decision-making process used to deal with health concerns, experiences with nontraditional remedies or therapies, and history of attending support groups. Respondents were asked to compare their overall well-being with that of their peers and to describe social, physical, and emotional characteristics typical of adults in their 20's, 40's, and 60's. Information on the work histories of respondents and their significant others was also elicited, with items covering the nature of their occupations, work-related physical and emotional demands, and how their personal health had correlated to their jobs. An additional series of questions focusing on childhood queried respondents regarding the presence/absence of their parents, religion, rules/punishments, love/affection, physical/verbal abuse, and the quality of their relationships with their parents and siblings. Respondents were also asked to consider their personal feelings of accomplishment, desire to learn, sense of control over their lives, interests, and hopes for the future.
The Datasets previously numbered 2 and 3 have been removed to avoid redundancies, and all datasets have been renumbered. Please refer to the readme file.
Dataset 2, Twin Screener Data, provides the first national sample of twin pairs ascertained randomly via the telephone.
Dataset 3, Coded Text Responses, describes how open-ended textual responses in the MIDUS 1 Computer-Assisted Telephone Interview (CATI) and Self-Administered Questionnaire (SAQ) were transformed into categorical numeric codes. These codes are included in a stand-alone dataset containing only those cases (N=3,950) that contained text data in their responses.
Online Analysis Only: Datasets 1, 2, and 3 were merged together by the SU_ID variable to form "Merged Data with Weights (Online Analysis Only)" (Dataset 4) for online analysis capabilities.
MIDUS also maintains a Colectica portal, which allows users to interact with variables across waves and create customized subsets. Registration is required.
Midlife in the United States (MIDUS 1) National Study of Daily Experiences (NSDE), 1996-1997 (ICPSR 3725)
Midlife in the United States (MIDUS 2), 2004-2006 (ICPSR 4652)
In 1995-1996, the MacArthur Midlife Research Network carried out a national survey of 7,108 Americans aged 25 to 74 (MIDLIFE IN THE UNITED STATES (MIDUS), 1995-1996 [ICPSR 2760]). The purpose of the study was to investigate the role of behavioral, psychological, and social factors in understanding age-related differences in physical and mental health. The study was innovative for its broad scientific scope, its diverse samples (which included twins and the siblings of main sample respondents), and its creative use of in-depth assessments in key areas (e.g., daily stress and cognitive functioning). A description of the study and findings from it are available at http://www.midus.wisc.edu. With support from the National Institute on Aging, a longitudinal follow-up of the original MIDUS samples: core sample (N = 3,487), metropolitan over-samples (N = 757), twins (N = 925 complete pairs), and siblings (N = 950), was conducted in 2004-2006. Guiding hypotheses for it, at the most general level, were that behavioral and psychosocial factors are consequential for physical and mental health. MIDUS 2 respondents were aged 35 to 86. Data collection largely repeated baseline assessments (e.g., phone interview and extensive self-administered questionnaire), with additional questions in selected areas (e.g., cognitive functioning, optimism and coping, stressful life events, and caregiving). To add refinements to MIDUS 2, an African American sample (N = 592) was recruited from Milwaukee, Wisconsin, who participated in a personal interview and completed a questionnaire paralleling the above assessments. Survey data for the Milwaukee sample are available in a separate project [ICPSR 22840]. Also administered was a modified form of the mail questionnaire, via telephone, to respondents who did not complete a self-administered questionnaire.
Midlife in the United States (MIDUS 2): Milwaukee African American Sample, 2005-2006 (ICPSR 22840)
Midlife in the United States (MIDUS 3), 2013-2014 (ICPSR 36346)
In 1995-1996, the MacArthur Midlife Research Network carried out a national survey of over 7,000 Americans aged 25 to 74 [ICPSR 2760]. The purpose of the study was to investigate the role of behavioral, psychological, and social factors in understanding age-related differences in physical and mental health. The study was innovative for its broad scientific scope, its diverse samples (which included siblings of the main sample respondents and a national sample of twin pairs), and its creative use of in-depth assessments in key areas (e.g. daily diary of stressful experiences [ICPSR 3725] and cognitive functioning [ICPSR 3596]) on a subset of participants. A detailed description of the study and findings generated by it are available at: http://www.midus.wisc.edu
With support from the National Institute on Aging, a follow-up of the original Midlife Development in the United States (MIDUS) sample was conducted in 2004 (MIDUS 2 [ICPSR 4652]). The daily stress and cognitive functioning projects were repeated and expanded at MIDUS 2; in addition the protocol was expanded to include biomarkers and neuroscience.
In 2013 a third wave (MIDUS 3) of survey data was collected on longitudinal participants. Data collection for this follow-up wave largely repeated baseline assessments (e.g., phone interview and extensive self-administered questionnaire), with additional questions in selected areas such as economic recession experiences. Cognitive functioning data were also collected at the same time, while data collection for the daily diary, biomarker, and neuroscience projects commenced in 2017.
MIDUS also maintains a Colectica portal, which allows users to interact with variables across waves and create customized subsets. Registration is required.
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 3): Retention Early Warning Project, 2018-2019 (ICPSR 38291)
Midlife in the United States (MIDUS): Psychological Experiences Follow-Up Study, 1998 (ICPSR 2911)
Midlife in the United States (MIDUS Refresher 1), 2011-2014 (ICPSR 36532)
In 2011-2014, the MIDUS Refresher study recruited a national probability sample of 3,577 adults, aged 25 to 74, designed to replenish the original MIDUS 1 baseline cohort and paralleling the five decadal age groups of the MIDUS 1 baseline survey [ICPSR 2760]. The MIDUS Refresher survey employed the same comprehensive assessments as those assembled on the existing MIDUS sample, but with additional questions about the effect of the economic recession of 2008-09.
The MIDUS Refresher collection is split into two datasets: Aggregate Data and Coded Text Data. The Coded Text Dataset provides coded responses to open-ended question items in the Aggregate Dataset. The survey data collection (Project 1) [MIDUS, ICPSR 2760] consisted of a 30-minute phone interview followed by two 50-page mailed self-administered questionnaires. Survey data were collected on demographic, psycho-social, and physical and mental health information. This new crosssectional MIDUS sample allows the examination of period effects on health (mental and physical) related to the economic recession by comparing the pre-recession MIDUS 1 sample with the post-recession MIDUS Refresher sample. A further objective of the MIDUS Refresher sample was to strengthen cross-project analyses in MIDUS by increasing the sample sizes available for testing hypotheses dealing with the interplay of key factors (e.g., socioeconomic status, gender, psychosocial factors, biological factors) in mid- and laterlife health. To that end, the MIDUS Refresher sample followed the same multi-disciplinary protocol established in the main MIDUS sample, in that after completing the survey protocol respondents were asked to complete a cognitive assessment by phone (Project 3) [MIDUS 3, ICPSR 36346] and later became eligible to participate in daily diary assessments (Project 2) [MIDUS 2, ICPSR 4652] biomarker assessments (Project 4) [MIDUS 2: Biomarker Project, ICPSR 29282] and neuroscience assessments (Project 5) [MIDUS 2: Neuroscience Project, ICPSR 28683].
The MIDUS Refresher was funded by the National Institute on Aging as two separate but related efforts: The MIDUS Refresher younger decades (MRY), was fielded in November, 2011, and recruited over 2,100 new participants aged 25 to 54; Funding was later added for the MIDUS Refresher older decades (MRO), which was fielded in June, 2013 and recruited over 1,400 new participants aged 55 to 74.
Demographic variables include age, sex, gender, race, religion, and marital status.
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), 2022-2024 (ICPSR 39670)
In 2011-2014, the MIDUS Refresher study recruited a national probability sample of 3,577 adults, aged 25 to 74, designed to replenish the original MIDUS 1 baseline cohort and paralleling the age groups of the MIDUS 1 baseline survey in 1995. The MIDUS Refresher survey employed the same comprehensive assessments as existing MIDUS sample, with additional questions about the effect of the Great Recession in 2008-09. Survey data were collected on demographic, psychosocial, and health and well-being information.
In 2022-2024, the second wave of survey data (MIDUS Refresher 2) was collected on longitudinal 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 data allow examination of period effects on health and well-being related to the COVID-19 pandemic by comparing the pre-pandemic MIDUS Refresher 1 data with the post-pandemic MIDUS Refresher 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 across various population groups in the U.S.
