Based on the historical population data for the ZIP code 61321, which corresponds to Dana in Illinois, the area has experienced fluctuations in population and population density over the years. The population peaked in 2011 at 469 residents and has since declined to 330 residents in 2022. The current population density stands at 10.14 people per square mile, indicating a very sparsely populated area.

Given the low population density, the ZIP code falls into the category of a remote rural area. Remote rural areas are characterized by minimal infrastructure, limited services, and large expanses of land per household. 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, based on the national average household size of 2.61, is approximately 126 units. This suggests that the area is likely composed of large, widely spaced properties, potentially with significant portions of undeveloped land.
