Remote rural areas are characterized by very sparse populations, minimal infrastructure, and limited services. The lifestyle in such areas is predominantly agricultural or undeveloped, focusing on privacy and self-sustainability. Residents often engage in outdoor and recreational activities due to the natural environment and the large expanses of land available per household, typically more than 5 acres.

The estimated housing units corresponding to the 2022 population, based on the national average household size of 2.61, is approximately 1,301 units. This relatively low number of housing units spread across the 86.83 square miles of the ZIP code further reinforces the remote rural nature of the area.
