The Rural Health Data Mapping initiative is dedicated to closing the information gap in healthcare access, delivery, and outcomes across Bangladesh’s remote and underserved rural communities. Drawing on extensive data collection, GIS technology, and community-based participatory approaches, the project systematically documents the availability and distribution of health facilities, workforce resources, essential medicines, patient flows, and service gaps. Special focus is placed on maternal and child health, disease prevalence, and the challenges of health infrastructure in rural areas. The mapping exercise enables precise identification of underserved regions, inequities in health resource allocation, and priority areas for intervention. The resulting health data maps and analytical findings provide evidence for government agencies, health NGOs, and development partners to design targeted programs, improve resource distribution, and monitor progress toward universal health coverage in rural Bangladesh.
