The Child Development Supplement (CDS) was created to provide researchers with comprehensive, nationally representative, longitudinal data on children and their families to study the dynamic process of early human capital formation. CDS-2014 was administered in 2014-15 and includes information collected from 4,333 children aged 0-17 and their primary caregivers in PSID families. More information about the study and data is provided in the CDS-2014 User Guide. CDS-2014 was funded by the Eunice Kennedy Shriver National Institute on Child Health and Human Development (R01 HD052646).   As one part of the study, youth 12 years and older were interviewed by telephone. The survey questionnaire is available here. Child reports of sensitive information in Section J on topics including sexual activity, contraception, pregnancy and births, delinquent behavior, and tobacco, drug, and alcohol are available under restricted data contract.
