Oak Grove, MN population, income and ZIP codes

Oak Grove city is a mid-size town in Minnesota, with 9,031 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #109 of 914 ranked by population — larger than 88% of them. The median age here is 44.5 years against 39.1 nationally, a slightly older profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Oak Grove city earn a median of $114,679 a year, 46% above the national figure of $78,538 and 52% above the $75,469 median for the 361 Minnesota cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 1.5% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Oak Grove city is valued at $394,100, 29.9% above the national figure and 64% above the $240,400 peer median, while median gross rent runs $2,052 a month, 45.9% above the national figure, or roughly $24,624 across a full year. A household on the local median income would put about 21.5% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 3.4×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 94.2% 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. 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.

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.
