St. Joseph, WI population, income and ZIP codes

St. Joseph CDP is a very small community in Wisconsin, with 530 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #530 of 807 ranked by population — larger than 34% of them. The median age here is 34.9 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 St. Joseph CDP earn a median of $84,583 a year, 7.7% above the national figure of $78,538 and 14% above the $73,880 median for the 395 Wisconsin 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 7.6% of residents here, below the 12.4% national rate.

The typical owner-occupied home in St. Joseph CDP is valued at $264,400, 12.9% below the national figure and 25% above the $211,900 peer median, while median gross rent runs $883 a month, 37.2% below the national figure, or roughly $10,596 across a full year. A household on the local median income would put about 12.5% 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 3.1×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 69.5% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
