Allentown, NJ

ZIP code 08501 is assigned to Allentown, NJ, and falls within Monmouth 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 6,297 people live inside it.

At 231 residents per square mile spread over 27.208 square miles, 08501 reads as a small-town area. It is a smaller 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 $133,015 places 08501 in the upper reaches of American postal codes, ahead of 94% 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 08501 costs well above the national median. A typical home is valued at $530,100 against a US median of $207,500, and median gross rent runs $1,457 a month. Ownership dominates: 91.4% 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 94.3% of housing units here. The median construction year is 1991, making the housing here from the later twentieth century. At 2.3%, vacancy is low — housing here is tightly held.

The population skews older than the national median, with a median age of 48.8 against 42 nationally. The average household holds 2.58 people, and 81.2% are family households.

Getting to work takes 34.5 minutes on average one way. The dominant mode is drove alone at 63.7% of workers, while 25.3% work from home. Commute patterns are one of the better proxies for how a place actually functions day to day.

Beyond addressing mail, 08501 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, 08501 offers a compact profile of Allentown: 6,297 residents, a median household income of $133,015, 59.7% of adults holding a bachelor's degree or higher, and an unemployment rate of 8.4%. 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. 08501 may cover parts of several distinct areas, and a single neighbourhood in Allentown 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.
