Mayfield Colony, SD population, income and ZIP codes

Mayfield Colony CDP is a very small community in South Dakota, with 84 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #324 of 485 ranked by population — larger than 33% of them. The median age here is 20.8 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Mayfield Colony CDP earn a median of not published a year. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 68.9% 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 Mayfield Colony CDP is valued at not published, while median gross rent runs not published a month. The homeownership rate is not published. 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.

A median age of 20.8 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address. With 84 residents, a handful of survey responses moves every median on this page. Compare Mayfield Colony CDP against its county rather than against national figures.

The Census withheld household income, home value, gross rent for Mayfield Colony 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.
