  • This table reflects program characteristics in 2001. Characteristics may have changed since then.

  • * With the exception of Indiana, where the Medicaid expansion portion of SCHIP represents a significant proportion of SCHIP enrollees, the data in this article include only new enrollees of separate, free-standing SCHIP programs (ie, Medicaid expansion SCHIP enrollees were not included).

  • New York’s Medicaid expansion covered children 15–18 years to 100% federal poverty level (FPL) who were not otherwise eligible for Medicaid.

  • Florida’s Medicaid expansion covered children <1 and 17–18 years to 100% of FPL who were not otherwise eligible for Medicaid.

  • § Indiana’s Medicaid expansion covered all children up to 150% of FPL who were not otherwise eligible for Medicaid.

  • Florida and New York had state-specific SCHIP precursor programs that became their respective SCHIP programs after the passage of Title XXI.

  • Entries on this row represent the total number of enrollments during federal fiscal year 2001.

  • ** All families enrolling in Indiana SCHIP were provided a 1-page letter inviting participation in the study; those who gave permission for the study were contacted by the Indiana study team. Although <2% of the forms received by the study team indicated refusal to participate, on some busy days in certain locations the permission forms were not distributed; thus the sample is technically a convenience sample.

  • †† Less than 20 interviews were completed after 9/11/01; all others were completed prior to that date.
