Number of adults aged 65 years and above in the U.S. in 2023, by healthcare coverage

"Private health insurance coverage includes any comprehensive private insurance plan (including health maintenance and preferred provider organizations). These plans include those obtained through an employer, purchased directly, purchased through local or community programs, or purchased through the Health Insurance Marketplace or a state-based exchange. Private coverage excludes plans that pay for only one type of service, such as dental, vision, or prescription drugs. People with private coverage may also have public coverage.

Public health plan coverage includes Medicaid, Children's Health Insurance Program (CHIP), state-sponsored or other government-sponsored health plan, Medicare, and military plans (TRICARE, Veterans Administration [VA], and CHAMP–VA). People with public coverage may also have private coverage.

People are considered uninsured if they currently do not have coverage through private health insurance, Medicare, Medicaid, CHIP, military (TRICARE, VA, and CHAMP–VA), other state-sponsored health plans, or other government program. People were also defined as uninsured if they only had Indian Health Service coverage or only had a private plan that paid for one type of service such as dental, vision, or prescription drugs.
