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.

The Future of Families and Child Wellbeing Study (FFCWS, formerly known as the Fragile Families and Child Wellbeing Study) follows a cohort of nearly 5,000 children born in large, U.S. cities between 1998 and 2000. The study oversampled births to unmarried couples; and, when weighted, the data are representative of births in large U.S. cities at the turn of the century. The FFCWS was originally designed to address four questions of great interest to researchers and policy makers:

1. What are the conditions and capabilities of unmarried parents, especially fathers?
2. What is the nature of the relationships between unmarried parents?
3. How do children born into these families fare?
4. How do policies and environmental conditions affect families and children?

The FFCWS consists of interviews with mothers, fathers, and/or primary caregivers at birth and again when children are ages 1, 3, 5, 9, 15, and 22. The parent interviews collected information on attitudes, relationships, parenting behavior, demographic characteristics, health (mental and physical), economic and employment status, neighborhood characteristics, and program participation. Beginning at age 9, children were interviewed directly (either during the home visit or on the telephone). The direct child interviews collected data on family relationships, home routines, schools, peers, and physical and mental health, as well as health behaviors.

A collaborative study of the FFCWS, the In-Home Longitudinal Study of Pre-School Aged Children (In-Home Study) collected data from a subset of the FFCWS Core respondents at the Year 3 and 5 follow-ups to ask how parental resources in the form of parental presence or absence, time, and money influence children under the age of 5. The In-Home Study collected information on a variety of domains of the child's environment, including: the physical environment (quality of housing, nutrition and food security, health care, adequacy of clothing and supervision) and parenting (parental discipline, parental attachment, and cognitive stimulation). In addition, the In-Home Study also collected information on several important child outcomes, including anthropometrics, child behaviors, and cognitive ability. This information was collected through interviews with the child's primary caregiver, and direct observation of the child's home environment and the child's interactions with his or her caregiver.

Similar activities were conducted during the Year 9 follow-up. At the Year 15 follow-up, a condensed set of home visit activities were conducted with a subsample of approximately 1,000 teens. Teens who participated in the In-Home Study were also invited to participate in a Sleep Study and were asked to wear an accelerometer on their non-dominant wrist for seven consecutive days to track their sleep (Sleep Actigraphy Data) and that day's behaviors and mood (Daily Sleep Actigraphy and Diary Survey Data).

An additional collaborative study collected data from the child care provider (Year 3) and teacher (Years 9 and 15) through mail-based surveys. Saliva samples were collected at Year 9 and 15 (Biomarker file and Polygenic Scores). The Study of Adolescent Neural Development (SAND) COVID Study began data collection in May 2020 following the onset of the COVID-19 pandemic. It included online surveys with the young adult and their primary caregiver.

The FFCWS began its seventh wave of data collection in October 2020, around the focal child's 22nd birthday. Data collection and interviews continued through January 2024. The Year 22 wave included a young adult (YA) survey with the original focal child and a primary caregiver (PCG) survey. Data were also collected on the children of the original focal child (referred to as Generation 3, or G3).

In 2017, the FFCWS team announced the Fragile Families (FF) Challenge, a collaborative effort in which participants were tasked with using machine learning methods and FFCWS data (Baseline to Year 9) to build a model that would predict six key outcomes at Year 15. Materials used in the FF Challenge have been archived in this collection.

The National Comorbidity Survey Replication Adolescent Supplement (NCS-A) was designed to estimate the lifetime-to-date and current prevalence, age-of-onset distributions, course, and comorbidity of DSM-IV disorders in the child and adolescent years of life among adolescents in the United States; to identify risk and protective factors for the onset and persistence of these disorders; to describe patterns and correlates of service use for these disorders; and to lay the groundwork for subsequent follow-up studies that can be used to identify early expressions of adult mental disorders.

The core NCS-A interview schedule was an adaptation of the World Health Organization Composite International Diagnostic Interview (CIDI). NCS-A also administered the non-verbal subtest (Matrices subtest) of the Kaufman Brief Intelligence Test (K-BIT).

In addition to interviewing adolescents, information was collected from a parent or a parent surrogate to obtain an additional perspective on the adolescent's mental health and its correlates. Information from parents focused on the five adolescent disorders for which previous methodological research has most consistently shown that parental reports are important for making diagnoses: attention-deficit/hyperactivity disorder, conduct disorder, oppositional defiant disorder, major depressive episode, and dysthymic disorder.

Demographic information collected by NCS-A includes age, citizenship status, country of birth, criminal history, ethnicity, grandparents' country of birth, language(s) spoken in the home, parents' country of birth, race, religion, and sex.

The data collection contains six data files: (1) data for the adolescent household and school respondents; (2) data for the parents who responded to the long self-administered questionnaire; (3) data for the parents who responded to both the long self-administered questionnaire and short telephone interview; (4) diagnostic variables derived from the data collected from the adolescents and parents; (5) K-BIT scores normed to the NCS-A adolescent sample; and (6) raw K-BIT data.

The NCS-2 was a re-interview of 5,001 individuals who participated in the Baseline (NCS-1). The study was conducted a decade after the initial baseline survey. The aim was to collect information about changes in mental disorders, substance use disorders, and the predictors and consequences of these changes over the ten years between the two surveys. The collection contains three major sections: the main survey, demographic data, and diagnostic data.

In the main survey, respondents were asked about general physical and mental health. Questions focused on a variety of health issues, including limitations caused by respondents' health issues, substance use, childhood health, life-threatening illnesses, chronic conditions, medications taken in the past 12 months, level of functioning and symptoms experienced in the past 30 days, and any services used by the respondents since the (NCS-1). Additional questions focused on mental disorders including depression, bipolar disorder, specific and social phobias, generalized anxiety, intermittent explosive disorder, suicidality, post-traumatic stress disorder, neurasthenia, pre-menstrual dysphoric disorder, attention deficit/hyperactivity disorder, oppositional defiant disorder, conduct disorder, and separation anxiety. Respondents were also asked about their lives in general, with topics including employment, finances, marriage, children, their social lives, and stressful life events experienced in the past 12 months. Additionally, two personality assessments were included consisting of respondents' opinions on whether various true/false statements accurately described their personalities. Another focus of the main survey dealt with substance use and abuse, nonmedical use of prescription drugs, and polysubstance use. Interview questions in the NCS-2 Main Survey were customized to each respondent based on previous responses in the Baseline (NCS-1).

The middle section contains demographic and other background information including age, education, employment, household composition, household income, marital status, and region.

The last section of the collection focused on whether respondents met diagnostic criteria for psychological disorders asked about in the main survey.

The National Survey of America's Families (NSAF) is a household survey that provides a comprehensive look at quantitative measures of the well-being of children, adults, and their families. While the focus of the survey is at the state level, the scope is national -- with a primary emphasis on low-income families. NSAF information was gathered from interviews conducted with the Most Knowledgeable Adult (MKA), the person in the household who was most knowledgeable about the questions being asked about the respondent, their spouse/partner (if applicable) and the focal child (or children). Data were collected from more than 40,000 families in two stages. First, a screener interview was administered to determine whether a household was eligible to complete the second, extended interview.

Two types of extended interviews were administered. Option A interviews were used in households with children under age 18. Option B interviews were used in childless adult households and also with emancipated minors. The extended interview was divided into several sections and is labeled A through P below:

• A. Student Status. This section contained two questions that asked whether the respondent was a student and whether that household was the respondent's usual residence.

• B. Health Status and Satisfaction. These questions asked about the respondent's satisfaction with health care, access to health care, the health status of the focal children, and the health status of the respondent.

• C. Parent/Child/Family Interaction and Education. This series of questions asked about education for focal children. Questions addressed the focal child's current grade (or the last grade completed) and the child's attitudes toward school and schoolwork, skipping school, suspensions, and changing schools. Questions were also asked about children over 11 years old working for pay and attending summer school.

• D. Household Roster. In this section, the name, age, and sex of all persons living in the household were recorded, and relationships between all household members were investigated.

• E. Health Care Coverage. Information was gathered about current health insurance coverage for the respondent, the respondent's spouse/partner, and the focal children. Questions were also asked about characteristics of that coverage and of periods in which family members had no insurance coverage.

• F. Health Care Use and Access. This section gathered information about health status, health care services received, and necessary health care services that were postponed during the preceding 12 months. Questions on routine care, overnight stays in hospitals, dental care, mental health care, women's health care, well-child care, and prescription medicines were also included.

• G. Child Care. In this section, respondents were queried as to child care arrangements including Head Start, child care centers, before- or after-school care, and babysitters. Questions were asked about the total number of hours per week in each care situation, the typical number of children cared for, the typical number of adult child care providers, and child care costs.

• H. Nonresidential Parent/Father. These questions determined whether a focal child had a nonresident parent, how often the child saw his/her nonresident parent, whether the nonresident parent provided financial support, and whether nonresident parents were required by child support orders to provide financial support.

• I. Employment and Earnings. This section contained a series of questions about the employment and earnings of the respondent and the spouse/partnerfor the current and preceding year. Topics included employment status, occupation, industry, employer-provided health insurance, hours worked, and earnings. Some questions were also asked about the earnings of other family members.

• J. Family Income. Family income also was identified from a wide variety of sources other than earnings from employment. These sources included public assistance (e.g., Aid to Families with Dependent Children [AFDC], General Assistance, Emergency Assistance, or vouchers), Food Stamps, child support, foster care payments, financial assistance from friends or relatives, unemployment compensation, workers' compensation or veterans' payments, Supplemental Security Income, Social Security, pension or annuity income, interest or dividend income, income from rental property, or any other income source.

For both types of assistance, periods in which the respondent's benefits were reduced or eliminated were identified, as were strategies for coping during such times. Current AFDC or Food Stamp recipients were asked about any requirements they had to fulfill (e.g., job search, training, etc.) in order to receive these benefits. Recipients were also asked questions about awareness of time limits and experiences with diversion. For respondents with children, questions were asked about benefits received in the previous year through the supplemental food program for Women, Infants, and Children (WIC) and free or reduced-cost school breakfast and lunch programs.

• L. Education and Training. This series of questions inquired about the highest grade completed, highest degree earned, participation in job training programs during the previous year, and classes taken for credit during the previous year.

The effect of economic hardship on the family's food consumption and ability to pay for housing costs was also assessed.

• N. Issues, Problems, and Social Services. Questions in this section covered the respondent's state of mind, feelings about his or her child (or children), constructive activities the child (or children) might have been involved with, the availability of social services in their community, problems the child (or children) might have had in the preceding year and efforts to obtain help for those problems, and the respondent's involvement in volunteer and religious activities.

• P. Closing. At the end of the survey, respondents were asked their opinions about welfare and working and about raising children. Closing questions asked for the respondent's ZIP code and, in households with foreign-born individuals, tracing information for use in a follow-up survey.

The 1997 NSAF data are available in nine parts and are organized into hierarchical, flat household-, family-, person-, adult-, and child-level files. A description of each is provided below:

1. Focal Child Data. This dataset contains data elements from the extended interview that are specific to focal children (FC1 and FC2). Select data items that were asked only of MKAs are also included. Information in this dataset is primarily from sections N (Issues, Problems, and Social Services) and P (Closing) of the extended interview. The dataset contains one record for each focal child.

2. Adult Pair Data. Included in this dataset is information collected from the extended interview about both the respondent and the respondent's spouse/partner. There is one observation per respondent and one per spouse (where applicable). Information in this dataset is primarily from sections I (Employment and Earnings) and L (Education and Training) of the extended interview.

3. Random Adult Data. Information in this person-level dataset is specific to a randomly selected adult, either the respondent or the spouse/partner. This situation occurs only in sections E (Health Insurance Coverage) and F (Health Care Access and Utilization) of the extended interview.

4. Childless Adult Data. This dataset contains data elements from the extended interview that are asked only of the respondent in Option B interviews. Variables in this dataset come mainly from section N (Issue, Problems, and Social Services) and P (Closing). There is one record per Option B interview in the dataset.

5. Family-Respondent Data. Information in this dataset centers around information about the family's use of health care and social services. This family-level dataset contains one observation per respondent. Because there could be more than one respondent per family, family-respondent level variables may have different values within a single family.

6. Household Data. This household-level dataset contains general information about the household such as the demographic characteristics of its members. Also contained in this dataset are administrative and process data such as housing subsidies, public housing, the number of bedrooms in the house, whether the home was owned or rented, and information pertaining to screeners and the completion of interviews.

7. Person Data. This dataset contains one observation for each person living in the household. Included in this dataset is demographic information as well as information on current health insurance status and income.

8. Social Family Data. Included in this dataset are items asked about the social family and variables aggregated at the social family level. The social family includes not only married partners and their children, but also unmarried partners, all of their children, and members of the extended family (anyone related by blood to the MKA, the spouse/partner, or their children). Among the survey items included are those variables indicating whether anyone in the social family had a particular type of income and health insurance. Also included are variables summarizing information across all members of a social family, such as the number of family members. There is one record for each social family.

9. CPS Family Data. Since the social family definition was used in fielding the NSAF, this dataset includes only variables created using the Current Population Survey (CPS) definition of family. A CPS family includes the householder, spouse of family householder, children in the family, and other relatives of the family household respondent. There is one record for each CPS family in this dataset.

The National Survey of America's Families (NSAF) is a household survey that provides a comprehensive look at quantitative measures of the well-being of children, adults, and their families. While the focus of the survey is at the state level, the scope is national -- with a primary emphasis on low-income families. NSAF information was gathered from interviews conducted with the Most Knowledgeable Adult (MKA), the person in the household who was most knowledgeable about the questions being asked about the respondent, their spouse/partner (if applicable) and the focal child (or children). Data were collected from more than 40,000 families in two stages. First, a screener interview was administered to determine whether a household was eligible to complete the second, extended interview.

Two types of extended interviews were administered. Option A interviews were used in households with children under age 18. Option B interviews were used in childless adult households and also with emancipated minors. The extended interview was divided into several sections and is labeled A through P below:

• A. Student Status. This section contained two questions that asked whether the respondent was a student and whether that household was the respondent's usual residence.

• B. Health Status and Satisfaction. These questions asked about the respondent's satisfaction with health care, access to health care, the health status of the focal children, and the health status of the respondent. It also covered questions about the respondent's awareness of specific insurance programs such as Medicaid, and those associated with the Children's Health Insurance Program (CHIP).

• C. Parent/Child/Family Interaction and Education. This series of questions asked about education for focal children. Questions addressed the focal child's current grade (or the last grade completed) and the child's attitudes toward school and schoolwork, skipping school, suspensions, and changing schools. Questions were also asked about children over 11 years old working for pay and attending summer school.

• D. Household Roster. In this section, the name, age, and sex of all persons living in the household were recorded, and relationships between all household members were investigated.

• E. Health Care Coverage. Information was gathered about current health insurance coverage for the respondent, the respondent's spouse/partner, and the focal children. Questions were also asked about characteristics of that coverage and of periods in which family members had no insurance coverage.

• F. Health Care Use and Access. This section gathered information about health status, health care services received, and necessary health care services that were postponed during the preceding 12 months. Questions on routine care, overnight stays in hospitals, dental care, mental health care, women's health care, well-child care, and prescription medicines were also included.

• G. Child Care. In this section, respondents were queried as to child care arrangements including Head Start, child care centers, before- or after-school care, and babysitters. Questions were asked about the total number of hours per week in each care situation, the typical number of children cared for, the typical number of adult child care providers, and child care costs.

• H. Nonresidential Parent/Father. These questions determined whether a focal child had a nonresident parent, how often the child saw his/her nonresident parent, whether the nonresident parent provided financial support, and whether nonresident parents were required by child support orders to provide financial support.

• I. Employment and Earnings. This section contained a series of questions about the employment and earnings of the respondent and the spouse/partner for the current and preceding year. Topics included employment status, occupation, industry, employer-provided health insurance, hours worked, and earnings. Some questions were also asked about the earnings of other family members.

• J. Family Income. Family income also was identified from a wide variety of sources other than earnings from employment. These sources included public assistance (e.g., Temporary Assistance for Needy Families [TANF], General Assistance, Emergency Assistance, vouchers), Food Stamps, child support, foster care payments, financial assistance from friends or relatives, unemployment compensation, workers' compensation or veterans' payments, Supplemental Security Income, Social Security, pension or annuity income, interest or dividend income, income from rental property, or any other income source.

Current TANF or Food Stamp recipients were asked about any requirements they had to fulfill (e.g., job search, training, etc.) in order to receive these benefits. Recipients were also asked questions about awareness of time limits and experiences with diversion. For respondents with children, questions were asked about benefits received in the previous year through the supplemental food program for Women, Infants, and Children (WIC) and free or reduced-cost school breakfast and lunch programs. Additional questions were asked about respondent experiences in obtaining government assistance for child care and health insurance through Medicaid and CHIP, and receipt and/or the use of the Earned Income Tax Credit (EITC) in 1998.

• L. Education and Training. This series of questions inquired about the highest grade completed, highest degree earned, participation in job training programs during the previous year, and classes taken for credit during the previous year.

• M. Housing and Economic Hardship. Questions covered the respondent's living arrangements, the name(s) of the lease- or mortgage- holder(s) in the household, and the amount of rent or mortgage paid monthly. Information was collected about financial contributions by the respondent or his/her spouse or partner to children under 18 years old living outside the household. The effect of economic hardship on the family's food consumption and ability to pay for housing costs was also assessed.

• N. Issues, Problems, and Social Services. Questions in this section covered the respondent's state of mind, feelings about his or her child (or children), constructive activities the child (or children) might have been involved with, the availability of social services in their community, problems the child (or children) might have had in the preceding year and efforts to obtain help for those problems, and the respondent's involvement in volunteer and religious activities.

• O. Race, Ethnicity, and Nativity. Race and ethnicity were asked for the respondent, the spouse/partner, and the focal children. For household members who were born outside the United States, country of origin and citizenship questions were asked.

• P. Closing. At the end of the survey, respondent's were asked their opinions about welfare and working and about raising children.The respondent's ZIP code and address were requested and tracing information was asked of households with families receiving welfare at any time since January 1997, for possible use in a follow-up survey.
