Medicaid serves which of the following populations?

Medicaid is a government program designed to provide health care coverage to individuals and families with low income. It assists a variety of vulnerable populations, allowing them access to necessary health care services they might otherwise be unable to afford. By focusing on those with limited financial resources, Medicaid plays a crucial role in ensuring that essential medical services are available to individuals who may struggle to pay for them.

The program is not limited to children, people with mental health issues, or military personnel; rather, it encompasses a broader demographic. This includes pregnant women, individuals with disabilities, elderly people needing long-term care, and working families who meet specific income criteria. Therefore, the premise that it serves "people who cannot afford health care services" accurately captures the overarching mission of Medicaid in providing necessary health care access to those in financial need.
