In 1997, the PSID Child Development Supplement(CDS) collected data on children ranging from 0 to 12 years old and performed two follow-up studies, the CDS I and CDS II. It had a sample size of 2500 children in the CDS II. However, the sample used in this study included about 1200 children because it was restricted to the children assessed in the CDS I living in metropolitan areas. The information was collected over a period, which allows for a better understanding of the children's family situation. It is also important to note that there is an oversample of black families in the PSID.
