St. Martin city, MN in context
How this area compares with national benchmarks.
St. Martin city is a very small community in Minnesota, with 322 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #596 of 914 ranked by population — larger than 34% of them. The median age here is 38.4 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. Martin city earn a median of $71,250 a year, 9.3% below the national figure of $78,538 and 6% below 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 17.1% of residents here, above the 12.4% national rate.
The typical owner-occupied home in St. Martin city is valued at $210,500, 30.6% below the national figure and 12% below the $240,400 peer median, while median gross rent runs $525 a month, 62.7% below the national figure, or roughly $6,300 across a full year. A household on the local median income would put about 8.8% 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 3×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 80.3% 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.
