Final answer:
Individual health insurance is purchased by individuals or families without access to group health insurance. Public health insurance and single-payer plans are alternatives to individual coverage.
Step-by-step explanation:
Individual health insurance is purchased by individuals or families who do not have access to group health insurance coverage. It is a type of insurance that provides coverage for an individual or their family members. Unlike group health insurance, which is usually provided by an employer or an organization, individuals have to purchase individual health insurance on their own or through the marketplace. Public health insurance, on the other hand, is typically provided by the government to eligible individuals or families who meet certain criteria. Single-payer plans refer to a system where a single entity, usually the government, pays for all healthcare costs.
