Medicaid and the Children’s Health Insurance Program (CHIP) are key supports for pregnant women and new mothers, as well as their children in the critical early years of life. Medicaid pays for nearly half of all births in the United States, including a greater share of births in rural areas, among young women, and women of color. Medicaid and CHIP also cover close to half of the nation’s children under age 3, making it the largest source of coverage for infants and toddlers.
