3. The percentage of children eligible for Medicaid and other public programs in the CTS was 30.8 percent in 1996–97, compared with an estimate of 29.5 percent based on the 1996 Medical Expenditure Panel Survey (MEPS). For more information on the estimate from MEPS, see T.M. Selden, J.S. Banthin, and J.W. Cohen, “Medicaid’s Problem Children: Eligible but Not Enrolled,”Health Affairs(May/June 1998 ): 192 –200.
4. A more thorough analysis of the coverage changes between 1996–97 and 1998–99 using the CTS data showed that eligibility expansions attributable to SCHIP did result in a considerable amount of substitution of public for private coverage, or crowding out. See P.J. Cunningham, J. Hadley, and J. Reschovsky, “The Effects of SCHIP on Children’s Health Insurance Coverage: Early Evidence from the Community Tracking Study,”Medical Care Research and Review(December 2002 ): 359 –383. This analysis was also updated to include the more recent data for 2000–01 and can be found at www.hschange.org .
