North Spearfish, SD population, income and ZIP codes

North Spearfish CDP is a small town in South Dakota, with 2,201 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #43 of 485 ranked by population — larger than 91% of them. The median age here is 38.9 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 North Spearfish CDP earn a median of $69,792 a year, 11.1% below the national figure of $78,538 and 7% above the $65,500 median for the 79 South Dakota 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 19.9% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in North Spearfish CDP is valued at $321,800, 6.1% above the national figure and 67% above the $192,800 peer median, while median gross rent runs $1,074 a month, 23.6% below the national figure, or roughly $12,888 across a full year. A household on the local median income would put about 18.5% 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 4.6×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 81.4% 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. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
