Underserved populations refer to groups of people who have limited access to resources and services, such as healthcare, education, and economic opportunities. These populations may include low-income individuals, racial and ethnic minorities, people with disabilities, and those living in rural or remote areas. Research in this area aims to identify the unique challenges and barriers faced by these populations and develop strategies to address their needs and improve their access to essential services. This may involve advocating for policy changes, implementing targeted programs, and increasing awareness of disparities in access to resources and opportunities.
