Boulder Junction, WI population, income and ZIP codes

Boulder Junction CDP is a very small community in Wisconsin, with 221 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #674 of 807 ranked by population — larger than 16% of them. The median age here is 39.8 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 Boulder Junction CDP earn a median of $55,972 a year, 28.7% below the national figure of $78,538 and 24% below the $73,880 median for the 395 Wisconsin cities we cover. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 21.3% 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 Boulder Junction CDP is valued at $312,500, 3% above the national figure and 47% above the $211,900 peer median, while median gross rent runs $854 a month, 39.3% below the national figure, or roughly $10,248 across a full year. A household on the local median income would put about 18.3% 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 5.6×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 28.6% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

With 221 residents, a handful of survey responses moves every median on this page. Compare Boulder Junction 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.
