What region is the region beyond a developed or settled area?

The region beyond a developed or settled area is often referred to as the "frontier" or "wilderness." This area typically consists of less populated or undeveloped land, which may include natural landscapes, forests, mountains, or uninhabited territories. It serves as a boundary between human civilization and untamed nature, often associated with exploration and resource discovery. In some contexts, it can also refer to areas that are economically or politically underdeveloped.
