Background and Objectives: This qualitative study explored perceived community strengths and health issues among 3 underserved and under-studied populations in the Atlanta, Georgia—older adults, Black or African American persons, and refugees/immigrants/migrants. Methods: Eight focus groups were conducted with 92 participants who were members of the 3 populations in Atlanta between November 2022 and March 2023. Results: Although there were variations among groups, all groups emphasized diversity within their community as the foundation of community strength. Elements of the built environment such as parks, convenience stores, the Atlanta Beltline, and food outlets bolstered community strength. Furthermore, community members being able to voice concerns and the responsiveness of governmental institutions helped form strong relationships to build a strong community. Regarding health issues, common physical health concerns included hypertension and obesity, with varied mental health issues. Accessibility and affordability of healthy foods were significant social concerns, alongside challenges in healthcare access such as navigating complex systems and high medical costs. Conclusion: Tailored interventions recognizing community strengths and addressing specific health issues are crucial for improving outcomes in marginalized communities, necessitating a health-in-all policies approach considering social, cultural, and structural determinants of health.
