Medicaid & CHIP Participation Rates

The figure below shows estimated Medicaid/Children's Health Insurance Program (CHIP) participation rates for children ages 0 to 18. Participation rates are defined as the ratio of Medicaid/CHIP-eligible enrolled children to the sum of Medicaid/CHIP-eligible enrolled children plus Medicaid/CHIP-eligible uninsured children, excluding those with both Medicaid/CHIP and private coverage (including military coverage) and those with Medicaid/CHIP coverage who do not have a known eligibility pathway for Medicaid or CHIP coverage.

Data from 2014 indicate that an estimated 91.0% of the eligible children in the United States without other coverage are enrolled in Medicaid/CHIP programs.

Figure Notes:

See source for how eligibility, participation, and uninsurance are defined. Estimates reflect edits to address apparent misreporting of coverage on the ACS.
* indicates that estimate is significantly different from the national average at the .05 level.
