Project Summary/Abstract: FRAGILE FAMILIES AND CHILD WELLBEING – YOUNG ADULTHOOD The Fragile Families and Child Wellbeing Study (FFCWS) is a birth cohort study following a stratified, multistage, population-representative sample of children born in large US cities between 1998 and 2000. This proposal requests funding to survey the children in young adulthood, around their 27th birthdays. The study began with interviews conducted with mothers and fathers at birth. Fathers were interviewed again when young adults were 1, 3, 5, and 9. Mothers were interviewed again when children were 1, 3, 5, and 9. Primary caregivers were interviewed when the young adults were ages 15 and 22. Young adults were assessed/interviewed at ages 3, 5, 9, 15, and 22. Saliva samples were collected from mothers at age 9 and from children at ages 9, 15, and 22. The original study design called for a large oversample of births to unmarried parents, and the sample is very diverse (the mothers are 48% Black, 27% Hispanic, and 21% white), making the data a valuable resource for studying racial and economic disparities in health and wellbeing. The age 22 interviews occurred in the context of the COVID-19 pandemic and included detailed questions about education, employment, income, health, housing, and family resource-sharing during the pandemic. To date, more than 8,700 researchers have used the data, resulting in the publication of more than 1,110 journal articles, 44 books and book chapters, 150 dissertations, and 115 working papers. Specific aims: (1) Collect data on the health and wellbeing of FFCWS young adults at age 27, including data on: a) socioeconomic status (education, employment, and income), b) family formation (intimate relationships, childbearing), c) health (self-reported physical and mental health), d) program participation (including health insurance, social services, cash and near-cash assistance, housing assistance) and e) systems involvement (experiences with the police and criminal justice system). (2) Collect innovative data on the social, economic, and physical environments of FFCWS young adults at age 27, including: a) family relationships and intergenerational support/obligations, and b) local area contexts such as policy regimes, neighborhood environments, and labor market conditions. (3) Obtain permission to access FFCWS young adults’ education, employment, health, and other administrative records (if not obtained at age 22). To accomplish these aims, we will contact approximately 3,600 young adults through a web-based survey around their 27th birthdays. Young adults who do not initially complete the web-based survey will receive phone or in-person follow-up and the interview will be administered by a trained interviewer.
