Data from the third round of the National Survey of America's Families show that between 1999 and 2002, the share of low-income uninsured children whose parents had heard of their state's separate SCHIP program increased from 47.2 to 70.6 percent. Among families familiar with Medicaid or SCHIP, 81.7 percent of low-income uninsured children had parents who said they would enroll their child if told the child was eligible.
