St. Pierre, MT population, income and ZIP codes

St. Pierre CDP is a very small community in Montana, with 467 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #161 of 497 ranked by population — larger than 67% of them. The median age here is 19.9 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. Pierre CDP earn a median of $34,141 a year, 56.5% below the national figure of $78,538 and 46% below the $62,992 median for the 94 Montana cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 38.8% 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. Pierre CDP is valued at not published, while median gross rent runs $388 a month, 72.4% below the national figure, or roughly $4,656 across a full year. A household on the local median income would put about 13.6% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. 54% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

A median age of 19.9 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address. With 467 residents, a handful of survey responses moves every median on this page. Compare St. Pierre CDP against its county rather than against national figures.

The Census withheld home value for St. Pierre CDP 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.
