For all topics based on the CPS on statehealthfacts.org, the grouping used for analysis is the health insurance unit (HIU), which groups individuals according to their insurance eligibility, rather than by relatedness or household.
For more details, see "Notes to Topics Based on the Current Population Survey (CPS)" at http://www.statehealthfacts.kff.org/methodology.

Percentages may not sum to 100% due to rounding effects.

For current Medicaid and Medicare enrollment figures, please refer to the Medicaid & SCHIP and "Medicare" sections, respectively, which report enrollment data from the Centers for Medicare and Medicaid Services (CMS).

SCHIP and individuals eligible for both Medicare and Medicaid (dual eligibles) are included in Medicaid.

Other Public (Federal) includes individuals covered through the military or Veterans Administration in federally-funded programs such as TRICARE (formerly CHAMPUS) as well as some non-elderly Medicare enrollees.
