Grafton, WI population, income and ZIP codes

Grafton village is a mid-size town in Wisconsin, with 12,274 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #79 of 807 ranked by population — larger than 90% of them. The median age here is 43.5 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 Grafton village earn a median of $88,634 a year, 12.9% above the national figure of $78,538 and 20% above the $73,880 median for the 395 Wisconsin 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 4.2% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Grafton village is valued at $301,300, essentially level with the national figure and 42% above the $211,900 peer median, while median gross rent runs $1,162 a month, 17.4% below the national figure, or roughly $13,944 across a full year. A household on the local median income would put about 15.7% 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 3.4×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 63.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
