Boulder Canyon, SD population, income and ZIP codes

Boulder Canyon CDP is a very small community in South Dakota, with 487 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #151 of 485 ranked by population — larger than 69% of them. The median age here is 37.9 years against 39.1 nationally, a slightly younger 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 Boulder Canyon CDP earn a median of $71,846 a year, 8.5% below the national figure of $78,538 and 10% above the $65,500 median for the 79 South Dakota 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% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Boulder Canyon CDP is valued at $510,400, 68.2% above the national figure and 165% above the $192,800 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 7.1×, 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. 52.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.

Home values sit at 7.1× 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 487 residents, a handful of survey responses moves every median on this page. Compare Boulder Canyon CDP against its county rather than against national figures.

The Census withheld gross rent for Boulder Canyon 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.
