Vulnerable populations are defined as those who:

The definition of vulnerable populations encompasses individuals who are at an increased risk of harm, whether due to physical, emotional, or social factors. This category of people may require tailored interventions or specific treatments due to their heightened susceptibility to adverse outcomes. Vulnerable populations often include the elderly, individuals with disabilities, the homeless, low-income groups, and those with chronic health conditions. These individuals may have barriers to accessing healthcare or may not receive adequate support during emergencies, making it critical for emergency medical personnel to recognize their unique needs.

The other options, while they may describe some individuals within vulnerable populations, do not provide a comprehensive definition that captures the breadth of vulnerability as related to health and social care. For example, societies may marginalize certain groups, but not all marginalized individuals fit into the definition of vulnerable populations needing specific treatment. Similarly, while language deficits and mental instability can make individuals vulnerable, they do not encompass the wider range of risks faced by various groups. Focusing only on immigrants who do not speak the language narrows the scope and overlooks other factors that contribute to vulnerability, such as economic status, access to education, or physical health.
