Oak Creek, WI

ZIP code 53154 is assigned to Oak Creek, WI, and falls within Milwaukee County. Like every US postal code, it began as a mail-routing device rather than a geographic boundary — the US Postal Service groups delivery routes under a single code so carriers and sorting equipment can process mail efficiently. Today it also serves as a practical shorthand for the area itself: roughly 36,473 people live inside it.

At 1,282 residents per square mile spread over 28.451 square miles, 53154 reads as a suburban area. It is a populous postal code, and density shapes almost everything else on this page — how people get to work, whether they own or rent, and what housing costs.

Household earnings run above the national median. At $93,120, 53154 sits comfortably in the upper half, ahead of 78% of them. The US median for comparison is $70,109. Bear in mind that median income describes the midpoint household, not the average — it is not pulled upward by a handful of very high earners the way a mean would be.

Housing in 53154 costs close to the national median. A typical home is valued at $305,100 against a US median of $207,500, and median gross rent runs $1,397 a month. The split between owning and renting is fairly even at 59.4% owner-occupied, which tends to indicate a mix of housing types rather than one dominant form.

The building stock is dominated by detached single-family houses, which account for 57.8% of housing units here. The median construction year is 1992, making the housing here from the later twentieth century. At 2.8%, vacancy is low — housing here is tightly held.

The population skews broadly in line with the national age profile, with a median age of 38.9 against 42 nationally. The average household holds 2.41 people, and 59.7% are family households.

Getting to work takes 24.7 minutes on average one way. The dominant mode is drove alone at 78.2% of workers, while 11.4% work from home. Commute patterns are one of the better proxies for how a place actually functions day to day.

Beyond addressing mail, 53154 does a lot of quiet administrative work. Retailers use it to calculate shipping and sales tax at checkout. Insurers use it to set premiums, since risk profiles vary geographically. Employers and marketers use it to define service areas. Government agencies use it to route benefits and organise reporting. If you have ever been asked for a postal code by a form that clearly does not intend to send you anything, this is why.

For anyone weighing a move, 53154 offers a compact profile of Oak Creek: 36,473 residents, a median household income of $93,120, 38.4% of adults holding a bachelor's degree or higher, and an unemployment rate of 0.8%. A handful of figures like these answer more relocation questions than most neighbourhood guides do.

One caution worth repeating: a postal code is not a neighbourhood. 53154 may cover parts of several distinct areas, and a single neighbourhood in Oak Creek may be split across more than one code. Boundaries also shift as USPS adjusts delivery routes. Treat the figures here as describing a delivery area, which is what they actually measure.
