Rock Falls, WI population, income and ZIP codes

Rock Falls CDP is a very small community in Wisconsin, with 184 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #704 of 807 ranked by population — larger than 12% of them. The median age here is 35.5 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 Rock Falls CDP earn a median of $68,500 a year, 12.8% below the national figure of $78,538 and 7% below the $73,880 median for the 395 Wisconsin 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 4.9% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Rock Falls CDP is valued at $165,000, 45.6% below the national figure and 22% below the $211,900 peer median, while median gross rent runs $900 a month, 36% below the national figure, or roughly $10,800 across a full year. A household on the local median income would put about 15.8% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 2.4×, 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. 81.6% 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.

With 184 residents, a handful of survey responses moves every median on this page. Compare Rock Falls CDP against its county rather than against national figures.

All values below were released by the Census for this exact geography, with no gap-filling on our side. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
