This report focuses on Medicaid and the State Children's Health Insurance Program (SCHIP) for low-income, uninsured children. It examines the 2000 National Survey of American Families data, concluding that in 2000, over half of all children and about 90 percent of low-income children were eligible for Medicaid or SCHIP coverage. Nearly 70 percent of uninsured children who qualified for public coverage were actually eligible for Medicaid, not SCHIP. Although many states had implemented policies to facilitate enrollment and increase retention, states were more willing to do so under SCHIP than Medicaid. (Contains 15 references.) (SM)
