St. Clair, MN population, income and ZIP codes

St. Clair city is a very small community in Minnesota, with 785 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #404 of 914 ranked by population — larger than 55% of them. The median age here is 38.8 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. Clair city earn a median of $101,375 a year, 29.1% above the national figure of $78,538 and 34% above the $75,469 median for the 361 Minnesota 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 4.1% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in St. Clair city is valued at $200,800, 33.8% below the national figure and 16% below the $240,400 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 2×, 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. 87.9% 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 785 residents, a handful of survey responses moves every median on this page. Compare St. Clair city against its county rather than against national figures.

The Census withheld gross rent for St. Clair city 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.
