South Hills, MT population, income and ZIP codes

South Hills CDP is a very small community in Montana, with 634 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #137 of 497 ranked by population — larger than 72% of them. The median age here is 47.5 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 South Hills CDP earn a median of $160,417 a year, 104.3% above the national figure of $78,538 and 155% above 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 0.8% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in South Hills CDP is valued at $652,400, 115% above the national figure and 160% above the $250,900 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 4.1×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 97.8% 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. 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.

With 634 residents, a handful of survey responses moves every median on this page. Compare South Hills CDP against its county rather than against national figures.

The Census withheld gross rent for South Hills 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.
