Which program provides health insurance specifically to low-income individuals and families?

Medicaid is a program designed to provide health insurance coverage specifically for low-income individuals and families. This federal and state program covers a wide range of health services, including hospital visits, preventive care, and long-term care. It is aimed primarily at vulnerable populations, including low-income children, pregnant women, elderly individuals, and people with disabilities.

While Medicare is focused on older adults and certain younger individuals with disabilities, it does not specifically address low-income requirements as Medicaid does. The Social Security Act encompasses various social welfare programs but is not a health insurance program itself. The Children's Health Insurance Program (CHIP) offers health coverage for children in families with incomes that are too high to qualify for Medicaid but too low to afford private coverage. Although CHIP addresses health insurance for specific children in low-income families, it doesn't encompass all low-income individuals and families, making Medicaid the most appropriate answer for the question regarding broad health insurance provision to low-income populations.
