Swan Lake, MT population, income and ZIP codes

Swan Lake CDP is a very small community in Montana, with 226 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #233 of 497 ranked by population — larger than 53% of them. The median age here is 43.6 years against 39.1 nationally, a slightly older profile than the country as a whole. 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 Swan Lake CDP earn a median of $78,125 a year, essentially level with the national figure of $78,538 and 24% above the $62,992 median for the 94 Montana cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 16.4% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Swan Lake CDP is valued at $492,900, 62.5% above the national figure and 96% above the $250,900 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 6.3×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 92.9% 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.

Home values sit at 6.3× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere. With 226 residents, a handful of survey responses moves every median on this page. Compare Swan Lake CDP against its county rather than against national figures.

The Census withheld gross rent for Swan Lake 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.
