Given the ZIP code's size of 38.52 square miles and the 2022 population density, this area can be classified as a remote rural region. Remote rural areas are characterized by very sparse populations, minimal infrastructure, and limited services. The lifestyle in such areas is predominantly agricultural or undeveloped, with a focus on privacy and self-sustainability. Residents often engage in outdoor and recreational activities due to the natural environment.

The estimated number of housing units corresponding to the 2022 population is 178.9, considering the national average household size of 2.61 people. This suggests that the area is likely to have large expanses of land per household, often more than 5 acres, which is typical of remote rural areas.
