Round Lake, MN population, income and ZIP codes

Round Lake city is a very small community in Minnesota, with 383 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #567 of 914 ranked by population — larger than 38% of them. The median age here is 44.9 years against 39.1 nationally, a slightly older 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 Round Lake city earn a median of $63,661 a year, 18.9% below the national figure of $78,538 and 16% below the $75,469 median for the 361 Minnesota 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 5.8% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Round Lake city is valued at $87,800, 71.1% below the national figure and 63% below the $240,400 peer median, while median gross rent runs $593 a month, 57.8% below the national figure, or roughly $7,116 across a full year. A household on the local median income would put about 11.2% 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 1.4×, 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. 74% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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 383 residents, a handful of survey responses moves every median on this page. Compare Round Lake city 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.
