Notes. States are assigned to terciles by ranking states by the predicted share of children enrolled in CHIP in 2009 and grouping states, so that roughly equal numbers of children would be included in each tercile. Source is author's calculations. Predicted CHIP enrollment shares are calculated using Medicaid and CHIP income eligibility criteria and CHIP waiting periods (see Appendix SA1). The characteristics of state populations are calculated from 2000 Census data (as reported in the Area Resources File).
