Isabel town, SD in context

How this area compares with national benchmarks.

Isabel town is a very small community in South Dakota, with 182 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #245 of 485 ranked by population — larger than 49% of them. The median age here is 38.1 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 Isabel town earn a median of $70,625 a year, 10.1% below the national figure of $78,538 and 8% above the $65,500 median for the 79 South Dakota cities we cover. 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 9.3% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Isabel town is valued at $49,300, 83.8% below the national figure and 74% below the $192,800 peer median, while median gross rent runs $756 a month, 46.2% below the national figure, or roughly $9,072 across a full year. A household on the local median income would put about 12.8% 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 0.7×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 56% 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.

With 182 residents, a handful of survey responses moves every median on this page. Compare Isabel town against its county rather than against national figures.
