Research, Evaluations, Maps and Data

ARC’s economists, mapping specialists, evaluators and data analysts regularly publish research reports and maps, as well as maintain an updated county-specific searchable data report tool. Research reports address critical socioeconomic issues impacting the Appalachian Region, while evaluations assess ARC’s own investment portfolios. ARC’s research and data helps policymakers and our regional partners better understand Appalachia’s challenges and make informed, effective decisions to address them. These publications also provide valid data for external researchers who are studying Appalachia.
