Data and Documentation
Data are free to download from Princeton University's Office of Population Research (OPR) data archive.
Currently, there are six waves of publicly available data including baseline and Year 1, Year 3, Year 5, Year 9, and Year 15 follow-ups. In order to protect the confidentiality of survey respondents, geographic identifiers, medical records data, contextual data (i.e., census tract characteristics), macroeconomic indicators, and genetic biomarkers are not available in the public use data files. Researchers may apply for these data via a restricted use contract.
FFCWS has documentation to help you understand and utilize the data. The Public Data Documentation page is a good place to start with details about sampling, survey weights, the data User Guides, codebooks, and questionnaires.
You can also use the FFCWS Metadata Explorer to navigate a full list of the FFCWS Public Data variables. Browse and Advanced Search functions are available or download and directly interact with the metadata CSV.
What is included in each survey?
There are interviews with both mothers and fathers at the child’s birth and again when children are ages one, three, five, and nine. 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. At Year 15, the primary caregiver (PCG) interview covers this material along with other measures previously collected in the PCG surveys. Additional components include home visits, teacher surveys, and saliva samples.
See the questionnaires at each wave or the Metadata Explorer for more details on the topics covered in the interviews. Many measures overlap with those used in other large-scale studies such as the Infant Health and Development Program (IHDP), Early Head Start, the Teenage Parent Demonstration, and the Early Childhood Longitudinal Study—Birth Cohort 2000 (ECLS-B). See the scales documentation at the end of each wave's User Guide for more details on established measures.
