The Fragile Families and Child Wellbeing Study
and The In-Home Longitudinal Study of Pre-School Aged Children

Data Alerts

May 15, 2008   Baseline, One-Year, Three-Year Core and Three-Year In-Home files have been re-released and are availble for download from the OPR data archive. These files now contain the final versions of the weights. Please visit the Fragaile Families web site for updated documentation.

The Fragile Families and Child Wellbeing Study

The Fragile Families and Child Wellbeing Study follows a cohort of nearly 5,000 children born in the U.S. between 1998 and 2000. The study over samples 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 Study was 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?; and (4) How do policies and environmental conditions affect families and children?

The Study consists of interviews with both mothers and fathers at birth and again when children are ages one, three and five. The parent interviews collect information on attitudes, relationships, parenting behavior, demographic characteristics, health (mental and physical), economic and employment status, neighborhood characteristics, and program participation.

Baseline, one-year follow-up, and three-year follow up data from the Core Study are available to the public. Upon registration, users can download data files from the first three waves of the core study. Mother and father data are provided in separate data files. Each file contains records for all 4,898 births regardless of whether the respondent was interviewed in a given wave. Sample flags on each file indicate which cases were interviewed at each wave. Documentation is available on the Fragile Families web site located at www.fragilefamilies.princeton.edu/documentation.asp.

The In-Home Longitudinal Study of Pre-School Aged Children

The In-Home Longitudinal Study of Pre-School Aged Children collects data from a subset of the Fragile Families Core respondents at the three- and five-year follow-ups to ask how parental resources in the form of parental presence or absence, time, and money influence children under the age of five.

The In-Home Study collects 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 Study also collects information on several important child outcomes, including anthropometrics, child behaviors, and cognitive ability. This information has been 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.

For more on the In-Home study, see the “Economic Status, Public Policy, and Neglect” grant on the research page of Center for Health and Wellbeing (CHW) website.

Data from the Three-Year In-Home Longitudinal Study of Pre-School Aged Children are also available for download as a standalone file. Please register for the Fragile Families data to get access. Documentation is available on the documentation page.
