Answer:
In the late 18th century, there were generally six or more colonists per square mile settled across most of the Appalachian mountain region.
In depth: The population density across most of the Appalachian mountain region varied over time. In 1900, the population density in the Southern Appalachians was about 35 per square mile
. However, in the late 18th century, there were pockets of settlement west of the Appalachian Mountains, with the generally settled area (6 people or more per square mile) covering a large swath of the Northeast and the Mid-Atlantic, and stretching south into Georgia
. Additionally, in 1820, the sparsely settled frontier territory gained population density west of the Appalachians
. Therefore, the population density across the region ranged from about 6 people or more per square mile in the late 18th century to about 35 per square mile in 1900.
