In this project, we will create a new CDS Online Data Center, a public data archive that focuses exclusively on CDS and provides important new functions and enhancements that will help researchers use data from CDS efficiently and effectively with minimal start-up time. All of these data have been processed and documented and are being distributed free of charge to the research community through the PSID Online Data Center. A variety of additional information was collected in all rounds of CDS, including weekday and weekend time diaries, anthropometric measurements, home and neighborhood observations, and saliva samples for subsequent genetic analysis (in CDS-2014). In all waves of CDS, extensive data on children?s development, health, and wellbeing were collected from children?s primary caregivers (PCGs, typically each child's mother) and from interviews with older children (aged 8+ years).
The first round of the ongoing CDS was fielded in 2014?2015, and the next round is planned for 2019-2020. By 2014, children in the original CDS cohort had reached adulthood, and CDS was relaunched as ongoing study in which data collection is planned at regular 5?6 year intervals on all children aged 0?17 years in PSID families. A second wave was collected on these same children in 2002/03 (CDS-II) when they were aged 5-18 years and a third wave was collected in 2007/08 (CDS-III) for children in this cohort who were aged 10?18 years. In 1997 PSID began to collect extensive data on children in the sample as part of the original PSID Child Development Supplement (CDS-I), which followed a cohort of PSID children aged 0-12 years. The Panel Study of Income Dynamics (PSID) is a longitudinal survey of a nationally representative sample of U.S.
