The states have enrolled large numbers of children and enrollment has grown rapidly from year to year. During FY 2002, 5.3 million children were enrolled in SCHIP for at least part of the year, (CMS 2003). Before that, enrollment (i.e., number of children enrolled at some point in the year) grew from 1.0 million in calendar 1998, to 2.0 million in FY 1999, and, further, to 3.3 million in FY 2000. Enrollment has grown most rapidly in separate programs. The proportion of children in SCHIP who were enrolled in separate programs rose from 65 percent in FY 1999 to 74 percent in FY 2001. 1 In part, this growth reflects an increase in the number of states that operate separate programs, whether alone or in combination with a Medicaid expansion program.
