Marine on St. Croix, MN population, income and ZIP codes

Marine on St. Croix city is a very small community in Minnesota, with 712 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #423 of 914 ranked by population — larger than 53% of them. The median age here is 58 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Marine on St. Croix city earn a median of $123,750 a year, 57.6% above the national figure of $78,538 and 64% above the $75,469 median for the 361 Minnesota 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.

The typical owner-occupied home in Marine on St. Croix city is valued at $464,100, 53% above the national figure and 93% above the $240,400 peer median, while median gross rent runs $2,200 a month, 56.5% above the national figure, or roughly $26,400 across a full year. A household on the local median income would put about 21.3% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 3.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 94.2% 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. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
