Key Events

Methodology

Estimates for all groups except for Medicare are based on the National Health Interview Survey and represent long-term trends in the number and percentage of persons under age 65 years with different types of health insurance coverage and with no coverage.

Estimates for Medicare are from the Centers for Medicare & Medicaid Services and include both persons over and under age 65 with Medicare.

Individual (nongroup) coverage includes persons covered by private insurance purchased directly as well as plans obtained through school or other means. Beginning in 2014, this category also includes plans purchased through the Health Insurance Marketplace or a state-based exchange.   

Military coverage includes TRICARE (CHAMPUS), CHAMP-VA, and VA coverage.  From 1997–2007 it also includes a small number of other government programs.

Percentage figures represent relationships between the observed groups and may differ from the groups’ percentages of the total U.S. adult population.
