The Future of Families and Child Wellbeing Study (FFCWS), Public Use, United States, 1998-2024 (ICPSR 31622)
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:
- What are the conditions and capabilities of unmarried parents, especially fathers?
- What is the nature of the relationships between unmarried parents?
- How do children born into these families fare?
- 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.

Guatemalan Survey of Family Health (EGSF), 1995 (ICPSR 2344)
The Guatemalan Survey of Family Health (EGSF) was undertaken to investigate the health of children under the age of five and women during pregnancy and childbirth residing in 60 communities within the departments (geopolitical units) of Chimaltenango, Suchitepequez, Totonicapan, and Jalapa in Guatemala. Data were collected at the household, individual, and community levels to gain an in-depth understanding of the way residents in these rural populations think about their health, treatment, and family relations.
Data at the household level (Parts 1-5, 90-92) provide information on household members, relation to household head, age, education, and language used.
The individual-level data (Parts 6-37) describe the respondent's background, marital/relationship history, social ties and social support, and economic status, along with health beliefs, a complete birth history, knowledge and use of contraception, health problems and treatment during the last two pregnancies, and anthropometry on mothers and children. Extensive data were gathered regarding the health problems and treatment for each of the two youngest children born since January 1990, with particular focus on diarrhea and respiratory infections.
The community data (Parts 41-60) supply information gathered from three knowledgeable individuals called "key informants" about occupations in the community, crops grown, wages, utilities and community services, and the history of the community. Parts 61-89 contain information regarding Health Posts (health care centers) through interviews conducted with key informants, doctors (Parts 72-80), and other health service providers (Parts 81-89), including traditional providers such as curers, midwives, and bone setters, regarding their practices, patients, referrals, fees, payment, and the use of specific treatments.

India Human Development Survey Panel (IHDS, IHDS-II), 2005, 2011-2012 (ICPSR 37382)
The India Human Development Survey (IHDS) is a nationally representative, multi-topic survey of 42,152 households in 1,503 villages and 971 urban neighborhoods across India. Data were originally collected from households during 2004-2005. Interviewers returned in 2011-2012 to re-interview these same households. During both waves of data collection, two one-hour interviews were conducted covering a large range of topics. The goal of the IHDS program is to document changes in the daily lives of Indian households in a society undergoing rapid transition.
This particular data collection merges the two waves of IHDS (known as IHDS and IHDS-II) into a harmonized pattern from the perspective view points of individuals, households, and eligible women. The data are presented in three different data formats: cross-sectional, wide, and long to facilitate a broader range of analysis options. Due to the specificity of geography and inclusion of sensitive / identifying topics there is a public-use and restricted-use rendition for each of the nine data files.
Indonesian Family Life Survey, 1993 (ICPSR 6706)
This release of the 1993 Indonesian Family Life Survey (IFLS-1-PR) is a revised and restructured version of the Wave 1 data. This data collection provides a broad range of economic, demographic, and health information at both the household and community levels across 13 provinces on the islands of Java, Sumatra, Bali, West Nusa Tenggara, Kalimantan, and Sulawesi. A sample of 7,224 households was interviewed during August 1993 through January 1994. Household-level data cover topics such as household characteristics, income, education of both adults and children, marriage histories, inter-household transfers, pregnancy history, and knowledge and use of contraceptives. At the community-facility level, information was gathered from village leaders and heads of village women's groups in each of the 321 enumeration areas (EAs) where the households were located. Questions were asked regarding community characteristics (transportation, water and sanitation, history of schools, and availability of health facilities), nurses, midwives, and paramedics (facility management and family planning history, vignettes on types of care), and traditional health practitioners (buying or making herbal medicines or using services of traditional practitioners, rituals, and incantations). When the household data are combined with the community-facility data, the 1993 Indonesian Family Life Survey provides a unique look at areas of fertility, family planning, infant and child health, education, migration, employment, and the social, economic, and health status of over 7,000 households in a diverse setting during a period of rapid demographic and socioeconomic change.
As of June 2015, there are four waves of data for the IFLS. However, a fifth wave of data collection has begun. Please see the IFLS Web site for more information on how to obtain these data.

National Survey of Families and Households, Wave 1: 1987-1988, [United States] (ICPSR 6041)
The National Survey of Families and Households (NSFH), Wave 1 (1987-1988) is the first of three waves in a longitudinal survey that was designed to study the causes and consequences of changes happening in families and households within the United States. At a time when the range of family structures was becoming more and more diverse, this study permitted a close examination of the resulting family compositions and household operations. One adult per household was randomly selected as the primary respondent, and there was a total of 13,007 respondents. In addition to the main interview conducted with the primary respondent, a shorter, self-administered questionnaire was given to the spouse or cohabitating partner, and also administered to the householder if he or she was a relative of the primary respondent.
A considerable amount of life-history information was collected, such as the respondent's family living arrangements in childhood, departures and returns to the parental home, and histories of marriage, separation, divorce, cohabitation, adoption, child custody arrangements, and stepfamily relations. Respondents were also asked about the relationship of household members to each other and the quality of their relationships with their parents, children, and in-laws. Information on economic well-being was also collected, including earnings from wages, self-employment income, interest, dividends, investments, pensions, Social Security, public assistance, and child support/alimony. Demographic information collected includes sex, age, marital status, education, and employment.
National Survey of Families and Households, Wave 2: 1992-1994, [United States] (ICPSR 6906)
The National Survey of Families and Households (NSFH), Wave 2 1992-1994, a longitudinal population-based survey of families and households in the United States, investigates the causes and consequences of changes in American family and household structure. This is the second wave of a three part survey. The current study, NSFH Wave 2, is the second follow up and was conducted in 1992-1994. The sample included all NSFH Wave 1 main respondents and spouse/partner with focal children and all other NSFH Wave 1 main respondents ages 45 and over in 2000, as well as their NSFH Wave 1 spouse/partner.
The Wave 2 survey included the following components: (1) an interview of all surviving members of the original sample via face-to-face personal interview, (2) a personal interview with the current spouse or cohabiting partner almost identical to the interview with the main respondent, (3) a personal interview with the original spouse or partner of the primary respondent in cases where this relationship had ended, (4) a telephone interview with "focal children" who were originally aged 13-18 in Wave 1, (5) a short telephone interview with "focal children" who were originally aged 5-12 in Wave 1, (6) short proxy interviews with a surviving spouse or other relative in cases where the original respondent had died or was too ill to interview, and (7) a telephone interview with a randomly-selected parent of the main respondent. Demographic information collected includes sex, age, marital status, education, and employment
