The Appalachian Region had a population of 26.6 million in 2023, a 4% increase — or just over one million more residents — than it had in mid-2010. Though two subregions have experienced growth, most of the region has lost population and its overall growth is slower than the national average of 7.8%.
The region’s population is generally aging at the same rate as the nation, with the median age rising to 41.3 years over the 2010-2023 period. However, certain portions of Appalachia are aging faster than others and the nation as a whole.
