In 2024, some 45.7 percent of Medicaid and CHIP enrollees were aged between 18 and younger, while adults aged 65 years accounted for only eight percent of enrollees. Medicaid program is funded jointly by the federal and state governments; it provided coverage to nearly 19.5 percent of the U.S. population in 2022.

Medicaid vs CHIP

Medicaid and the Children’s Health Insurance Program (CHIP) both provide health insurance coverage for children from low-income families. Children who are not eligible for Medicaid but who would otherwise be unable to obtain insurance through a family plan are covered by CHIP. More than five million children were enrolled in CHIP in the U.S. in 2023.

Medicaid and CHIP funding rate

The Federal Medical Assistance Percentages (FMAPs) are used to calculate the amount of federal matching funds for State Medicaid and CHIP programs. To encourage states to expand coverage for uninsured children, the federal matching rates for CHIP are generally 15 points higher than the Medicaid rate. However, unlike permanent federal funding for Medicaid, CHIP federal funding is capped and is due to expire in FY 2027.
