ZIP code 53204

ZIP 53204 is a small city in Milwaukee County, Wisconsin, with 40,008 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #18 of 783 ranked by population — larger than 97% of them. The median age here is 29.1 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 ZIP 53204 earn a median of $43,645 a year, 44.4% below the national figure of $78,538. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 32.6% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in ZIP 53204 is valued at $106,000, 65.1% below the national figure, while median gross rent runs $964 a month, 31.4% below the national figure, or roughly $11,568 across a full year. A household on the local median income would put about 26.5% 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 2.4×, 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. 26.4% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. 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.

A median age of 29.1 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.

ZIP 53204 is tabulated inside Milwaukee County, Wisconsin, one of 36 ZIP areas the Census publishes for that county and 783 across Wisconsin. This is a dense urban ZIP, where a single postal boundary can hold more residents than an entire rural county. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 53204 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 53204 reports a median household income of $43,645, 36% below the $68,482 county median, and 41% below the $73,420 typical WI ZIP. Owner-occupied homes are valued at a median of $106,000, 48% below the county figure and 51% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $964 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

A taxable purchase made inside 53204 carries 7.9% at the register, assembled from the Milwaukee jurisdiction stack: the Wisconsin state rate plus every county, municipal and special district levy that reaches this address. Because those district boundaries were drawn for schools, transit and hospital funding rather than for mail delivery, two addresses inside 53204 can legitimately fall under different totals — the rate shown here is the one that applies to the dominant jurisdiction.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 53204 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
