South Fork, CO population, income and ZIP codes

South Fork town is a very small community in Colorado, with 615 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #266 of 482 ranked by population — larger than 44% of them. The median age here is 57.5 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 Fork town earn a median of $75,938 a year, 3.3% below the national figure of $78,538 and 12% below the $86,484 median for the 223 Colorado 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 10% of residents here, below the 12.4% national rate.

The typical owner-occupied home in South Fork town is valued at $381,600, 25.8% above the national figure and 16% below the $453,600 peer median, while median gross rent runs $874 a month, 37.8% below the national figure, or roughly $10,488 across a full year. A household on the local median income would put about 13.8% 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 5×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 68.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

A median age of 57.5 puts South Fork town well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. With 615 residents, a handful of survey responses moves every median on this page. Compare South Fork town against its county rather than against national figures.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
