Prospect, KY

ZIP code 40059 is assigned to Prospect, KY, and falls within Jefferson 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 19,899 people live inside it.

At 705 residents per square mile spread over 28.206 square miles, 40059 reads as a small-town area. It is a mid-sized postal code by population, 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 here sit well above the national picture. The median household income of $165,000 places 40059 in the upper reaches of American postal codes, ahead of 98% 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 40059 costs well above the national median. A typical home is valued at $533,800 against a US median of $207,500, and median gross rent runs $1,844 a month. Ownership dominates: 88.2% of occupied homes are owner-occupied, which usually signals an established residential area with relatively low turnover.

The building stock is dominated by detached single-family houses, which account for 89.0% of housing units here. The median construction year is 1998, making the housing here from the later twentieth century.

The population skews older than the national median, with a median age of 48 against 42 nationally. The average household holds 2.51 people, and 77.6% are family households.

Getting to work takes 27.8 minutes on average one way. The dominant mode is drove alone at 70.3% of workers, while 20.6% work from home. Commute patterns are one of the better proxies for how a place actually functions day to day.

Beyond addressing mail, 40059 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, 40059 offers a compact profile of Prospect: 19,899 residents, a median household income of $165,000, 70.6% of adults holding a bachelor's degree or higher, and an unemployment rate of 4.6%. 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. 40059 may cover parts of several distinct areas, and a single neighbourhood in Prospect 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.
