Stillwater ZIP codes — Stillwater County, Montana

Stillwater County is a mid-size town in Montana, with 9,052 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 47.4 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Stillwater County earn a median of $81,503 a year, 3.8% above the national figure of $78,538. 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 8.3% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Stillwater County is valued at $355,600, 17.2% above the national figure, while median gross rent runs $968 a month, 31.2% below the national figure, or roughly $11,616 across a full year. A household on the local median income would put about 14.3% 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 4.4×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 80.8% 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.
