Health insurance programs subsidized by taxpayer dollars are an important source of health insurance coverage for children in the United States. The National Health Interview Survey (2022) estimated that about 44% of American children under the age of 18 had publicly subsidized health insurance coverage.  While public health insurance coverage for children may come through Medicare, state-sponsored or other government-sponsored health plans, and military health plans, the primary sources of publicly supported coverage for children are Medicaid and the Children's Health Insurance Program (CHIP).  Medicaid is the joint federal-state program that offers health insurance to eligible individuals with limited incomes, whereas CHIP is a joint federal-state effort to make health insurance to children from low-income families that don't qualify for Medicaid coverage.  As of January 2023, federal reports indicate that there were almost 41.9 million children in the U.S. enrolled in Medicaid or separate CHIP programs.

As of January 2023, federal data reveals that the Mid-Eastern region of the U.S., which includes the District of Columbia and five states, had over 6.1 million children enrolled in either Medicaid or separate CHIP programs.  Of the 49 states and the District of Columbia that reported their total Medicaid child and CHIP enrollment as of January 2023, the Mid-Eastern region accounted for about 14.6% of the total.  Here is a summary look at Medicaid child and CHIP enrollment in the Mid-Eastern U.S. as of January 2023:
