St. Regis, MT population, income and ZIP codes

St. Regis CDP is a very small community in Montana, with 344 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #191 of 497 ranked by population — larger than 61% of them. The median age here is 30.3 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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. Regis CDP earn a median of $50,833 a year, 35.3% below the national figure of $78,538 and 19% below the $62,992 median for the 94 Montana 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 34.3% 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 St. Regis CDP is valued at $186,100, 38.7% below the national figure and 26% below the $250,900 peer median, while median gross rent runs $908 a month, 35.4% below the national figure, or roughly $10,896 across a full year. A household on the local median income would put about 21.4% 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 3.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 54.1% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

With 344 residents, a handful of survey responses moves every median on this page. Compare St. Regis 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.
