Appalachia is made up of 423 counties across 13 states and spans 206,000 square miles, from Southern New York to Northern Mississippi. The region’s 26.4 million residents live in parts of Alabama, Georgia, Kentucky, Maryland, Mississippi, New York, North Carolina, Ohio, Pennsylvania, South Carolina, Tennessee, and Virginia, and all of West Virginia.
The region also comprises three federally recognized and five state recognized Native American tribal communities, with tribal entities in Appalachian Alabama, Georgia, Mississippi, New York and North Carolina.
Appalachia Then and Now
Since 1965, ARC has funded over 34,000 economic development projects and invested over $6 billion in Appalachia, which has been matched by over $12 billion in other federal, state and local funding sources.
While significant improvements have been made in key economic factors such as poverty, per capita income and high school graduation rates, Appalachia still lags behind the rest of the nation on a number of socioeconomic indicators. More work is needed to help Appalachia recover from economic disruptions, address the substance use disorder crisis, and attract additional private sector investment.
