Alexandria, SD population, income and ZIP codes

Alexandria city is a very small community in South Dakota, with 725 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #111 of 485 ranked by population — larger than 77% of them. The median age here is 37 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 Alexandria city earn a median of $92,500 a year, 17.8% above the national figure of $78,538 and 41% 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 1.8% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Alexandria city is valued at $168,300, 44.5% below the national figure and 13% below the $192,800 peer median, while median gross rent runs $714 a month, 49.2% below the national figure, or roughly $8,568 across a full year. A household on the local median income would put about 9.3% 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 1.8×, 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. 82.3% 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. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

With 725 residents, a handful of survey responses moves every median on this page. Compare Alexandria city against its county rather than against national figures.
