Based on the historical population data for the ZIP code 61486, which covers the village of Viola in Illinois, the area has consistently maintained a low population density over the past decade. In 2022, the population density was approximately 30.84 people per square mile, with an estimated population of 1,245 individuals.

Given these population figures, the ZIP code 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, taking advantage of the natural environment and the large expanses of land available per household, typically more than 5 acres.

The estimated number of housing units corresponding to the 2022 population is around 477, assuming the national average household size of 2.61 persons per household. This suggests that the area is composed of widely dispersed homes, likely on large plots of land, which is consistent with the remote rural classification.
