In which areas is the population of the Appalachian region primarily located?

The population of the Appalachian region is primarily located on coastal plains and in river valleys due to the geography that supports sustainable living conditions. The coastal plains and river valleys provide more fertile land and better access to water resources, which are crucial for agriculture and transportation. This accessibility allows for the establishment of communities and the development of economic activities such as farming, fishing, and trade.

In contrast, while the mountainous areas of the region may have some population, they are less conducive to large-scale settlement due to their rugged terrain and limited accessibility. Dense forests and rural areas are characteristic of parts of the Appalachian region, but populations tend to congregate in areas where resources and accessibility are better, which correlates with the coastal plains and river valleys. Urban centers do exist but are not the primary areas of population density within the broader Appalachian region.
