Underserved populations refer to groups of people who do not have adequate access to essential services such as healthcare, education, housing, or employment opportunities. These populations often face barriers such as poverty, discrimination, and limited resources that prevent them from enjoying the same level of access and quality of services as other groups in society. Research in this area aims to understand the needs and challenges faced by underserved populations, identify strategies to address these disparities, and advocate for policies and programs that promote equity and social justice for all individuals. By focusing on underserved populations, researchers seek to improve the overall well-being and quality of life for these marginalized groups.
