Definition: Unduplicated number of children ages 0-18 ever enrolled in Medicaid and/or the Children's Health Insurance Program (CHIP) during the federal fiscal year per 1,000 children (e.g., in the 2016 federal fiscal year, 510.5 per 1,000 California children were enrolled in Medicaid).

Footnote: Medicaid is a federal program providing health coverage to eligible low-income children and families; Medi-Cal is California's Medicaid program. CHIP (Children’s Health Insurance Program) is a federal program providing coverage to children/youth up to age 19 in families with incomes too high to qualify them for Medicaid, but too low to afford private coverage. California’s CHIP program was called the Healthy Families Program (HFP). Although California continues to receive CHIP funding, in 2013 HFP enrollees were transitioned into Medi-Cal. Data reflect the funding source through which a child last had coverage in the federal fiscal year (FY). FY 2013 and FY 2014 data for individual programs are not comparable to other years due to duplication across programs. FY 2014 data, and FY 2015 and FY 2016 CHIP and total data are estimates due to the exclusion of certain unborn CHIP enrollees in reporting. Data are reported by individual states. States may subsequently revise their current and/or historical data. U.S. data reflect the sum of state-level reports. Implementation of CHIP and Medicaid may differ from state to state. The abbreviation S refers to that data that have been suppressed because they are not comparable.
