Mill Creek, IL population, income and ZIP codes

Mill Creek village is a very small community in Illinois, with 32 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1422 of 1,462 ranked by population — larger than 2% of them. The median age here is 45.8 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Mill Creek village earn a median of $107,500 a year, 36.9% above the national figure of $78,538 and 45% above the $74,244 median for the 698 Illinois cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 15.6% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Mill Creek village is valued at not published, while median gross rent runs not published a month. 100% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

Median income runs above the national figure while poverty also runs above it — a split distribution, not a uniformly comfortable place. Averages hide that; the two numbers together do not. With 32 residents, a handful of survey responses moves every median on this page. Compare Mill Creek village against its county rather than against national figures.

The Census withheld home value, gross rent for Mill Creek village 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.
