Final answer:
Medicaid is the public health insurance program that is funded by federal, state, and local monies, providing coverage for low-income individuals and focusing on certain groups such as children, the elderly, and the disabled.
Step-by-step explanation:
The nationwide public health insurance program that is jointly funded by federal-state-local monies is Medicaid. Created by Congress in 1965, Medicaid provides medical insurance to certain low-income individuals, including those below the poverty line, and focuses on families with children, the elderly, and the disabled. Each state administers its own Medicaid program, which can result in varying levels of service and eligibility requirements, despite the federal government's role in funding.
