Sample weighting stratified by year was used for all analyses to produce nationally representative estimates.
Race and ethnicity were self-reported as captured by the National Health Interview Survey. Participants were asked whether they identified with 1 or more of the following racial groups: white, black/African American, Alaskan Native or American Indian, Chinese, Filipino, Asian Indian, or other Asian. Those reporting Chinese, Filipino, Asian Indian, or other Asian race were grouped as Asian. Participants were also asked whether they identified with 1 or more of the following ethnicities: not Hispanic/Spanish origin, Mexican, Mexican American, Puerto Rican, Cuban/Cuban American, Dominican (republic), Central or South American, other Latin American (type not specific), other Spanish, or multiple Hispanic. Those reporting any of the ethnicities, with exception of not Hispanic/Spanish origin, were categorized as Spanish-Hispanic-Latino.
Total column number exceeds the number with insurance because participants could list having multiple types of insurance. Column percentages provided.
