The term "vulnerable population" refers to groups of people who are at a higher risk for negative health outcomes due to various social, economic or environmental factors. These factors can include poverty, lack of access to healthcare services, limited education, exposure to violence and abuse, living in areas with high levels of pollution or crime, among others. Vulnerable populations often experience higher rates of chronic diseases, mental illnesses, and premature death compared to the general population. Addressing the needs of vulnerable populations is an important aspect of public health efforts, as these groups are at a greater risk for preventable health problems.
