D-D approach—change between 1987 and 1996 for poverty-related children less change over same time period for slightly higher-income children: Children made eligible for Medicaid under the poverty-related expansions in the 1980s are the treatment group and children with slightly higher income levels (defined as those in the income groups ultimately made eligible for SCHIP as of 2000) are the primary comparison group; controls included a variety of sociodemographic characteristics, as well as income and health status. Service use refers to previous 12 months.
