Although Pennsylvania ranks in the top 5 among states with the lowest rates of uninsured children under 19, 8.3 percent of the state's 3 million children lack health insurance. This Kids Count special report provides information on Pennsylvania's uninsured children. The report indicates that more than one-fourth are estimated to be eligible for the Children's Health Insurance Program (CHIP) but are not enrolled, almost one-half are eligible for Medical Assistance benefits but are not enrolled, and the remaining fourth are ineligible for coverage under any government program. In addition, the report charts families' estimated eligibility for CHIP by poverty status and age, provides comparison of the federal poverty income guidelines and program thresholds for health coverage, details the numbers of children receiving assistance through Medical Assistance and CHIP, examines the relationship between family income level and health insurance, and charts the percentage of children in Pennsylvania and the United States with employer-based health coverage. A table details the type of CHIP program, upper eligibility income for a family of three, and the percent of uninsured children in each state. The report concludes with a description of the study's methodology and data sources. (KB)
