The Americans' Changing Lives (ACL) survey series is an ongoing, nationally representative, longitudinal study focusing especially on differences between Black and White Americans in middle and late life. These data constitute the first, second, third, fourth, fifth, and sixth waves in a panel survey covering a wide range of sociological, psychological, mental, and physical health items. Wave I of the study began in 1986 with a nation face-to-face survey of 3,617 adults ages 25 and up, with Black Americans and people aged 60 and over over-sampled at twice the rate of the others. Wave II constitutes face-to-face re-interviews in 1989 of those still alive. Survivors have been re-interviewed by telephone, and when necessary face-to-face, in 1994 (Wave III), 2001/02 (Wave IV), 2011 (Wave V), and 2019/21 (Wave VI).

Please note that for Wave VI, the majority of data collection occurred in 2019, with only a small subset (n=39) of participants surveyed in 2021.

ACL was designed and sought to investigate the following: (1) The ways in which a wide range of activities and social relationships that people engage in are broadly "productive," (2) how individuals adapt to acute life events and chronic stresses that threaten the maintenance of health, effective functioning, and productive activity, and (3) sociocultural variations in the nature, meaning, determinants, and consequences of productive activity and relationships. Among the topics covered are interpersonal relationships (spouse/partner, children, parents, friends), sources and levels of satisfaction, social interactions and leisure activities, traumatic life events (physical assault, serious illness, divorce, death of a loved one, financial or legal problems), perceptions of retirement, health behaviors (smoking, alcohol consumption, overweight, rest), and utilization of health care services (doctor visits, hospitalization, nursing home institutionalization, bed days). Also included are measures of physical health, psychological well-being, and indices referring to cognitive functioning.

Demographic information provided for individuals includes household composition, number of children and grandchildren, employment status, occupation and work history, income, family financial situation, religious beliefs and practices, ethnicity, race, education, sex, and region of residence.

This study comprises the second round of the physician survey component of the Community Tracking Study (CTS) sponsored by the Robert Wood Johnson Foundation. The CTS is a national study designed to track changes in the American health care system and the effects of the changes on care delivery and on individuals. Central to the design of the CTS is its community focus. Sixty sites (51 metropolitan areas and 9 nonmetropolitan areas) were randomly selected to form the core of the CTS and to be representative of the nation as a whole. As in the first round of the physician survey (COMMUNITY TRACKING STUDY PHYSICIAN SURVEY, 1996-1997: [UNITED STATES] (ICPSR 2597)), the second round was administered to physicians in the 60 CTS sites and to a supplemental national sample of physicians. The survey instrument collected information on physician supply and specialty distribution, practice arrangements and physician ownership of practices, physician time allocation, sources of practice revenue, level and determinants of physician compensation, provision of charity care, career satisfaction, physicians' perceptions of their ability to deliver care, views on care management strategies, and various other aspects of physicians' practice of medicine. In addition, primary care physicians (PCPs) were asked to recommend courses of action in response to some vignettes of clinical presentations for which there was no prescribed method of treatment.

Dataset 3, the Site and County Crosswalk Data File, identifies the counties that constitute each CTS site.

Dataset 4, the Physician Survey Summary File, contains site-level estimates and standard errors of the estimates for selected physician characteristics, e.g., the percentage of physicians who were foreign medical school graduates, the mean age of physicians, and the mean percentage of patient care practice revenue from Medicaid.

The objectives of the study were: (1) To determine the nature, incidence, and prevalence of fraud victimization among elderly consumers in Arizona and Florida; (2) To identify risk and protective factors associated with fraud victimization in this population; and (3) To evaluate the elderly population's awareness and use of state-based programs, including reporting behavior to law enforcement.

The study is comprised of data from telephone surveys of 2,000 aged 60 years and older Arizona (n = 1,000) and Florida (n = 1,000). The survey was obtained via computer assisted telephone interviewing (CATI) administered by Precision Research in June and July of 2011. Data were collected seven days a week during specific times of the day that had the greatest probability of contacting a respondent. The interviews were primarily conducted in English but a Spanish survey instrument was constructed and used when necessary.

This data collection is comprised of data from the 2006 Annual Social and Economic Supplement (ASEC), and is a part of the Current Population Survey (CPS) Series. The Census Bureau conducts the ASEC (known as the Annual Demographic File prior to 2003) over a three-month period, in February, March, and April, with most of the data collected in the month of March. The ASEC uses two sets of survey questions, the basic CPS and a set of supplemental questions.

The CPS, administered monthly, is a labor force survey providing current estimates of the economic status and activities of the population of the United States. Specifically, the CPS provides estimates of total employment (both farm and nonfarm), nonfarm self-employed persons, domestics, and unpaid helpers in nonfarm family enterprises, wage and salaried employees, and estimates of total unemployment.

In addition to the basic CPS questions, respondents were asked questions from the ASEC, which provides supplemental data on poverty, geographic mobility/migration, and work experience. Comprehensive work experience information was given on the employment status, occupation, and industry of persons aged 15 and over. Additional data for persons aged 15 and older were available concerning weeks worked and hours per week worked, reason not working full time, total income and supplemental income components. Additional data are included that cover training and assistance received under welfare reform programs such as job readiness training, child care services, or job skill training. Data covering nine noncash income sources: food stamps, school lunch program, employer-provided group health insurance plan, employer-provided pension plan, personal health insurance, Medicaid, Medicare, CHAMPUS or military health care, and energy assistance are also included.

Demographic variables include age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, occupation, and income. Data on employment and income refer to the previous calendar year, although demographic data refer to the time of the survey.

The original ASEC data provided by the Census Bureau are distributed in a hierarchical file structure, with three record types present: Household, Family, and Person. The ASEC is designed to be a multistage stratified sample of housing units, where the hierarchical file structure can be thought of as a person within a family within a household unit. Here the main unit of analysis is the household unit. For ease of analysis at the person-level, ICPSR created a rectangular file structure that contains a record for every person with the respective Household and Family variables prepended to the Person variables. Part 1 contains the rectangular data file and Part 2 contains the original hierarchical data file.

Specifically, the CPS provides estimates of total employment (both farm and nonfarm), nonfarm self-employed persons, domestics, and unpaid helpers in nonfarm family enterprises, wage and salaried employees, and estimates of total unemployment. Data from the CPS are provided for the week prior to the survey.

All veterans aged 17 or older received questions from the Veterans Supplement, which provides estimates on the demographic and labor force characteristics of veterans who have a service-connected disability in comparison to all other veterans. The data also made distinctions between Gulf War era veterans and Vietnam theater veterans; the latter being veterans who served in Vietnam, Laos, or Cambodia. Estimates were also provided on the number of veterans with or without a service-connected disability and their labor force participation rate, occupational distributions, unemployment rates, periods of military service, and use of certain educational and job training programs. The Veterans Supplement portion of the study was designed to be a self-response survey and general interviewers were instructed to make up to two personal or telephone callbacks before accepting a proxy interview.

Demographic variables include age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, occupation, and income.

This data collection is comprised of responses from two sets of survey questionnaires, the basic Current Population Survey (CPS) and a survey administered as a supplement to the August 2006 basic CPS questionnaire on the topic of tobacco use in the United States. The Tobacco Use Supplement (TUS), sponsored by the National Cancer Institute and the Centers for Disease Control and Prevention, was also administered in May 2006 (ICPSR 24781) and January 2007 (ICPSR 24783). These three supplements comprise the 2006-2007 waves of TUS data.

The basic CPS, administered monthly, collects labor force data about the civilian noninstitutional population living in the United States. Moreover, the CPS provides current estimates of the economic status and activities of this population which includes estimates of total employment (both farm and nonfarm), nonfarm self-employed persons, domestics, and unpaid helpers in nonfarm family enterprises, wage and salaried employees, and estimates of total unemployment. Data from the CPS are provided for the week prior to the administration of the survey.

The TUS, like most CPS supplements, was designed to be a proxy response supplement, meaning a single respondent could provide answers for all eligible household members, provided the respondent was a household member 15 years of age or older. Unique to the TUS design were also a set of self-respondent supplement questions. All household members age 15 years and older who had completed the basic CPS core items were eligible for the August 2006 supplement items. Beginning in August 2006, 15-17 year old respondents were phased out of the TUS and they were entirely omitted from the January 2007 sample due to Census Bureau budget constraints.

The TUS consisted of items PEA1 through SINTTP. Self-respondents were eligible for the entire supplement, whereas proxy respondents were only eligible for certain items. Information was collected from proxies on topics such as smoking status (items PEA1-PEA3) and the use of other tobacco-related products, such as pipes, cigars, chewing tobacco, and snuff (items PEAJ1A1-PEAJ1A4 and PEJ2A1-PEJSA4).

In addition to these smoking and other tobacco use status questions, self-respondents were queried on the following topics depending on their smoking/tobacco use status (i.e., every day, some days, or former cigarette smokers and/or users of other non-cigarette tobacco products):

• Smoking history

• Current cigarette smoking prevalence and consumption

• Type of cigarettes smoked

• Price of last pack/carton of cigarettes purchased and state of purchase

• Medical and dental advice to quit smoking

• Attempts and intentions to quit smoking cigarettes and/or other forms of tobacco use

• Awareness of 1-800-QUIT-NOW

• Workplace smoking policies and smoking rules in the home

• Attitudes toward smoking in public places

Another generally unique feature to the 2006-2007 TUS-CPS was the administration of questions to former smokers on their previous level of addiction, use of quitlines, and advice from health professionals. This feature enables comparisons between characteristics of former smokers (or successful quitters) and current smokers attempting to quit.

Demographic information collected include age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, family relationship, occupation, and income.

This data collection is comprised of responses from two sets of survey questionnaires, the basic Current Population Survey (CPS) and a biennial survey on the topic of veterans in the United States, which was administered as a supplement to the August 2007 CPS questionnaire.

This data collection is comprised of responses from two sets of survey questionnaires, the basic Current Population Survey (CPS) and a survey on the topic of food security in the United States, which was administered as a supplement to the December 2001 CPS questionnaire.

The CPS, administered monthly, is a labor force survey providing current estimates of the economic status and activities of the population of the United States. Specifically, the CPS provides estimates of total employment (both farm and nonfarm), nonfarm self-employed persons, domestics, and unpaid helpers in nonfarm family enterprises, wage and salaried employees, and estimates of total unemployment. Data from the CPS are provided for the week prior to the survey.

The supplement was intended to research the full range of severity of food insecurity as experienced in United States households. The food security questions were asked of all interviewed households, as appropriate. Respondents were queried on how much the household spent for food, their use of federal and community food assistance programs, whether they were able to afford enough food, food sufficiency, and ways of coping with not having enough food.

The supplement was intended to research the full range of severity of food insecurity as experienced in United States households. Food Security supplement items were used by the supplement sponsor to produce a scaled measure of food insecurity. Therefore, responses to individual items should not be used as meaningful measures of food insufficiency, food insecurity, or hunger. Measures that combine information from multiple items (HRFS12M1 and following) are generally considered to be more reliable measures of food security and food insecurity. The food security questions were asked of all interviewed households, as appropriate. Respondents were queried on how much the household spent for food, their use of federal and community food assistance programs, food sufficiency, and ways of coping with not having enough food.

Unique to the TUS design were also a set of self-respondent questions. Self-respondents were eligible for the entire supplement, whereas proxy respondents were only eligible for questions on the topics of smoking status (items PES32-PES34) and the use of other tobacco products; for example, pipes, cigars, chewing tobacco, and snuff (items PES62A-PES63B).

Additionally, self-respondents were asked various questions depending on their smoking status -- former, everyday, or occasional (items PES36-PES46 and PES55-PES61). Current everyday and occasional smokers were then asked whether the medical community had advised them to quit smoking or if they were planning to quit in the near future (items PES47-PES54). Self-respondents were further queried on smoking policies in their work place (items PES67-PES71), smoking rules in the home (item PES73) and questions on opinions about smoking (items PES72, PES75-PES77).

Administrative information was collected on who the proxy respondents were, the language in which the interview was conducted, and the survey method (telephone vs. personal-visit interviews; Computer Assisted Telephone Interviewing (CATI) vs. Computer Assisted Personal Interviewing (CAPI)). Demographic information collected includes age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, family relationship, occupation, and income.

The sponsor of the biennial supplement survey were the Department of Veterans Affairs (VA), formerly the Veterans Administration, and the Department of Labor.

The CPS, administered monthly, is a labor force survey providing current estimates of the economic status and activities of the population of the United States. Specifically, the CPS provides estimates of total employment (both farm and nonfarm), nonfarm self-employed persons, domestics, and unpaid helpers in nonfarm family enterprises, wage and salaried employees, and estimates of total unemployment. Data from the CPS are provided for the week prior to the survey.

All veterans aged 17 or older received questions from the Veterans Supplement, which provides estimates on the demographic and labor force characteristics of veterans who have a service-connected disability in comparison to all other veterans. The data also made distinctions between Gulf War era veterans and Vietnam theater veterans; the latter being veterans who served in Vietnam, Laos, or Cambodia. Estimates were also provided on the number of veterans with or without a service-connected disability and their labor force participation rate, occupational distributions, unemployment rates, periods of military service, and use of certain educational and job training programs. The Veterans Supplement portion of the study was designed to be a self-response survey and general interviewers were instructed to make up to two personal or telephone callbacks before accepting a proxy interview.

Demographic variables include age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, occupation, and income.

This data collection is comprised of responses from two sets of survey questionnaires, the basic Current Population Survey (CPS) and a survey administered as a supplement to the June 2001 questionnaire on the topic of tobacco use in the United States. The Tobacco Use Supplement (TUS), sponsored by the National Cancer Institute and the Centers for Disease Control and Prevention, was also administered in November 2001 (ICPSR 4044) and February 2002 (ICPSR 4031). These three supplements comprise the 2001-2002 waves of TUS data.

The basic CPS, administered monthly, collects labor force data about the civilian noninstitutional population living in the United States. Moreover, the CPS provides current estimates of the economic status and activities of this population which includes estimates of total employment (both farm and nonfarm), nonfarm self-employed persons, domestics, and unpaid helpers in nonfarm family enterprises, wage and salaried employees, and estimates of total unemployment. Data from the CPS are provided for the week prior to the administration of the survey.

All household members age 15 years and older who had completed the basic CPS monthly items were eligible for the TUS, which consisted of items PES32 through PES77. The TUS was mainly designed to be a proxy response survey, meaning a single respondent could provide answers for all eligible household members. Unique to the TUS design were also a set of self-respondent questions. Self-respondents were eligible for the entire supplement, whereas proxy respondents were only eligible for questions on the topics of smoking status (items PES32-PES34) and the use of other tobacco products; for example, pipes, cigars, chewing tobacco, and snuff (items PES62A-PES63B).

Additionally, self-respondents were asked various questions depending on their smoking status -- former, everyday, or occasional (items PES36-PES46 and PES55-PES61). Current everyday and occasional smokers were then asked whether the medical community had advised them to quit smoking or if they were planning to quit in the near future (items PES47-PES54). Self-respondents were further queried on smoking policies in their work place (items PES67-PES71), smoking rules in the home (item PES73) and questions on opinions about smoking (items PES72, PES75-PES77).

Administrative information was collected on who the proxy respondents were, the language in which the interview was conducted, and the survey method (telephone vs. personal-visit interviews; Computer Assisted Telephone Interviewing (CATI) vs. Computer Assisted Personal Interviewing (CAPI)). Demographic information collected includes age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, family relationship, occupation, and income.

This data collection is comprised of responses from two sets of survey questionnaires, the basic Current Population Survey (CPS) and a survey administered as a supplement to the June 2003 questionnaire on the topic of tobacco use in the United States. The Tobacco Use Supplement (TUS), sponsored by the National Cancer Institute and the Centers for Disease Control and Prevention, was also administered in February 2003 (ICPSR 4526) and November 2003 (ICPSR 4528). These three supplements comprise the 2003 wave of TUS data.

Moreover, the CPS provides current estimates of the economic status and activities of this population which includes estimates of total employment (both farm and nonfarm), nonfarm self-employed persons, domestics, and unpaid helpers in nonfarm family enterprises, wage and salaried employees, and estimates of total unemployment. Data from the CPS are provided for the week prior to the administration of the survey.

The TUS, like most CPS supplements, was designed to be a proxy response supplement, meaning a single respondent could provide answers for all eligible household members, provided the respondent was a household member 15 years of age or older. Unique to the TUS design were also a set of self-respondent supplement questions. All household members age 15 years and older who had completed the basic CPS core items were eligible for the June 2003 supplement items.

The TUS consisted of items PEA1 through PEK5. Self-respondents were eligible for the entire supplement, whereas proxy respondents were only eligible for certain items. Information was collected from proxies on topics such as smoking status (items PEA1-PEA3) and the use of other tobacco-related products, such as pipes, cigars, chewing tobacco, and snuff (items PEJ1a -PEJ2a).

In addition to these smoking status and other tobacco use questions, self-respondents were queried on the following topics depending on their smoking/tobacco use status (i.e., every day, some days, or former cigarette smokers and/or users of other non-cigarette tobacco products):

• Smoking history

• Current cigarette smoking prevalence and consumption

• Type of cigarettes smoked

• Price of last pack/carton of cigarettes purchased and state where purchased

• Medical and dental advice to quit smoking

• Attempts and intentions to quit smoking cigarettes and/or other forms of tobacco use

• Workplace smoking policies and smoking rules in the home

• Attitudes toward smoking in public places

Another generally unique feature to the 2003 TUS-CPS was the administration of questions to former smokers on their previous level of addiction, products/resources/methods used to quit smoking, and advice from health professionals. This feature enables comparisons between characteristics of former smokers (or successful quitters) and current smokers attempting to quit.

Administrative information was collected on who the proxy respondents were, the language in which the interview was conducted, and the survey method (telephone vs. personal-visit interviews; Computer Assisted Telephone Interviewing (CATI) vs. Computer Assisted Personal Interviewing (CAPI)). Demographic information collected include age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, family relationship, occupation, and income.

This data collection is comprised of responses from two sets of survey questionnaires, the basic Current Population Survey (CPS) and a survey administered as a supplement to the May 2006 questionnaire on the topic of tobacco use in the United States. The Tobacco Use Supplement (TUS), sponsored by the National Cancer Institute and the Centers for Disease Control and Prevention, was also administered in August 2006 (ICPSR 24782) and January 2007 (ICPSR 24783). These three supplements comprise the 2006-2007 waves of TUS data.

The TUS -- like most CPS supplements -- was designed to be a proxy response supplement, meaning a single respondent could provide answers for all eligible household members, provided the respondent was a household member 15 years of age or older. Unique to the TUS design were also a set of self-respondent supplement questions. All household members age 15 years and older who had completed the basic CPS core items were eligible for the May 2006 supplement items. Beginning in August 2006, 15-17 year old respondents were phased out of the TUS and they were entirely omitted from the January 2007 sample due to Census Bureau budget constraints.

The TUS consisted of items PEA1 through SINTTP. Self-respondents were eligible for the entire supplement, whereas proxy respondents were only eligible for certain items. Information was collected from proxies on topics such as smoking status (items PEA1-PEA3) and the use of other tobacco-related products, such as pipes, cigars, chewing tobacco, and snuff (items PEAJ1A1-PEAJ1A4 and PEJ2A1-PEJSA4).

In addition to these smoking and other tobacco use status questions, self-respondents were queried on the following topics depending on their smoking/tobacco use status (i.e., every day, some days, or former cigarette smokers and/or users of other non-cigarette tobacco products):

• Smoking history

• Current cigarette smoking prevalence and consumption

• Type of cigarettes smoked

• Price of last pack/carton of cigarettes purchased and state of purchase

• Medical and dental advice to quit smoking

• Attempts and intentions to quit smoking cigarettes and/or other forms of tobacco use

• Awareness of 1-800-QUIT-NOW

• Workplace smoking policies and smoking rules in the home

• Attitudes toward smoking in public places

Another generally unique feature to the 2006-2007 TUS-CPS was the administration of questions to former smokers on their previous level of addiction, use of quitlines, and advice from health professionals.

This data collection is comprised of responses from two sets of survey questionnaires, the basic Current Population Survey (CPS) and a survey on the topic of food security in the United States, which was administered as a supplement to the September 2000 CPS questionnaire.

The CPS, administered monthly, is a labor force survey providing current estimates of the economic status and activities of the population of the United States. Specifically, the CPS provides estimates of total employment (both farm and nonfarm), nonfarm self-employed persons, domestics, and unpaid helpers in nonfarm family enterprises, wage and salaried employees, and estimates of total unemployment. Data from the CPS are provided for the week prior to the survey.

The supplement was intended to research the full range of severity of food insecurity as experienced in United States households. The food security questions were asked of all interviewed households, as appropriate. Respondents were queried on how much the household spent for food, their use of federal and community food assistance programs, whether they were able to afford enough food, food sufficiency, and ways of coping with not having enough food.

Demographic variables include age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, occupation, and income.

The Family Exchanges Study Wave 1 (FESI) was conducted in 2008 by the Institute for Survey Research at Temple University. The original 634 "target" or core sample was recruited from African American and White respondents aged 40-60 living in Philadelphia and the surrounding counties--Bucks, Chester, Delaware, and Montgomery. To be eligible for the study, respondents had to have at least one living parent and one living offspring over 18 years of age. Temple University sought to recruit the parents, spouse, and up to three offspring over 18 years of age into the study. All target, parent, and spouse surveys were conducted by telephone. Offspring were given the option of completing the survey by telephone or web. A total of 337 parents, 511 offspring (with another 80 by web and 1 listed as other for a total of 592), and 197 spouses were successfully recruited into the first wave of the study.

This collection includes four data files, one for each type of participant: target, spouse, parent, and offspring. For each of these participants, there are data related to relationships with other family members, perceptions of family members, and views on key social issues. Demographic information includes gender, marital status, education level, religion, age, race, ethnicity, and employment status.

Offspring were given the option of completing the survey by telephone or web.

For the Wave 2 data collection, the Survey Research Center at Pennsylvania State University attempted to contact all FESI respondents again, as well as collect updated information for spouses/romantic partners, parents, and up to 4 age-eligible offspring. The survey instruments were drawn largely from the first wave of data collection. This collection includes eight data files. These data files include five main study datasets: target, spouse, spouse without target, parent, and offspring. This collection also includes three diary datasets: target diary, parent diary, offspring diary. For each participant, there are data related to relationships with other family members, perceptions of family members, and views on key social issues. Demographic information includes gender, marital status, education level, religion, age, race, ethnicity, and employment status.

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.

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.
