This subcontract supported collaboration between UNC-Chapel Hill and the University of Chicago to conduct a cost-benefit analysis of the long-term outcomes from the Abecedarian and Carolina Approach to Responsive Education (CARE) studies. The intent was to share data collected on both the Abecedarian sample and that for CARE at age 30 and also data to be collected on the health status of individuals in both samples in order to learn the extent to which the benefits associated with early childhood educational intervention for poor children are reflected in better economic circumstances and better health in adults who qualified, as infants, as being at risk for developmental delays and academic failure.
