Sun Prairie, MT population, income and ZIP codes

Sun Prairie CDP is a small town in Montana, with 1,514 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #73 of 497 ranked by population — larger than 85% of them. The median age here is 49.5 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 Sun Prairie CDP earn a median of $61,004 a year, 22.3% below the national figure of $78,538 and 3% 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 9.3% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Sun Prairie CDP is valued at $156,800, 48.3% below the national figure and 38% below the $250,900 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 2.6×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 98.5% 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. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

The Census withheld gross rent for Sun Prairie 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.
