The historical population data for the ZIP code 62518, which corresponds to Chestnut in Illinois, indicates a consistently low population density over the years. In 2022, the population density was 9.35 people per square mile, with a total population of 240 individuals. This extremely low population density suggests that the area is classified as remote rural, characterized by vast expanses of land per household and a predominantly agricultural or undeveloped lifestyle.

Given the estimated 91.95 housing units in 2022, based on the national average household size of 2.61, the area likely features large, widely-spaced properties with minimal infrastructure and limited services. Residents of this ZIP code are expected to lead a lifestyle focused on privacy and self-sustainability, with common activities revolving around outdoor recreation and appreciation of the natural environment.

The population trend in the ZIP code shows a gradual decline from 355 in 2010 to 240 in 2022, with minor fluctuations in between. This suggests that the area has not experienced significant urban development or population growth over the past decade.
