Big Rock, IL population, income and ZIP codes

Big Rock village is a small town in Illinois, with 1,208 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #642 of 1,462 ranked by population — larger than 56% of them. The median age here is 40.6 years against 39.1 nationally, a slightly older 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 Big Rock village earn a median of $126,667 a year, 61.3% above the national figure of $78,538 and 71% above 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 4.6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Big Rock village is valued at $290,100, 4.4% below the national figure and 62% above the $179,100 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 2.3×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 96% 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. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

The Census withheld gross rent for Big Rock 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.
