The historical population data for the ZIP code 60152, which corresponds to Marengo in Illinois, reveals a relatively stable population trend over the past decade. The population has remained within the range of 11,200 to 11,900 residents, with minor fluctuations from year to year. The most recent data point for 2022 shows a population of 11,443, slightly lower than the peak observed in 2011 at 11,923.

The ZIP code area spans 94.6 square miles, resulting in a population density of approximately 121 people per square mile in 2022. This population density falls within the range typically associated with rural areas, which are characterized by larger living spaces, lower infrastructure density, and a community-oriented lifestyle centered around local schools and small businesses.

Given the national average household size of 2.61, the estimated number of housing units corresponding to the 2022 population is 4,384. This suggests that the area likely features a mix of single-family homes and smaller multi-family dwellings, with lot sizes potentially ranging from 1 to 5 acres, as is common in rural settings.
