The historical population data for the ZIP code 61370, which corresponds to Tonica in Illinois, reveals a predominantly rural lifestyle with a low population density. Over the past decade, from 2010 to 2022, the population has fluctuated between 883 and 1,053 residents, with the most recent data point in 2022 showing a population of 883 and a density of 21.66 people per square mile.

Given the ZIP code's size of 40.76 square miles and the 2022 population, the estimated number of housing units is approximately 338, assuming the national average household size of 2.61 persons per household. This low housing unit count, coupled with the sparse population density, suggests that the area is characterized by large expanses of land per household, likely exceeding 5 acres on average.

The population density of 21.66 people per square mile in 2022 falls well below the threshold of 50 people per square mile typically associated with remote rural areas. This indicates that Tonica and the surrounding area within the ZIP code have very sparse populations, minimal infrastructure, and limited services. The lifestyle in such areas is often focused on privacy, self-sustainability, and agricultural or undeveloped land use, with residents engaging in outdoor and recreational activities due to the natural environment.
