Northfield city, MN in context
How this area compares with national benchmarks.
Northfield city is a mid-size town in Minnesota, with 20,678 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #59 of 914 ranked by population — larger than 93% of them. The median age here is 28.3 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Northfield city earn a median of $92,000 a year, 17.1% above the national figure of $78,538 and 22% above 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 7.2% of residents here, below the 12.4% national rate.
The typical owner-occupied home in Northfield city is valued at $305,300, essentially level with the national figure and 27% above the $240,400 peer median, while median gross rent runs $1,036 a month, 26.3% below the national figure, or roughly $12,432 across a full year. A household on the local median income would put about 13.5% 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 3.3×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 69.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
A median age of 28.3 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.
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.
