Mounds, IL population, income and ZIP codes

Mounds city is a very small community in Illinois, with 855 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #741 of 1,462 ranked by population — larger than 49% of them. The median age here is 36.5 years against 39.1 nationally, a slightly younger profile than the country as a whole. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Mounds city earn a median of $27,333 a year, 65.2% below the national figure of $78,538 and 63% below the $74,244 median for the 698 Illinois cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 46.6% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in Mounds city is valued at not published, while median gross rent runs $559 a month, 60.2% below the national figure, or roughly $6,708 across a full year.

The Census withheld home value for Mounds city because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
