Dublin, PA

ZIP code 18917 is assigned to Dublin, PA, and falls within Bucks 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 2,176 people live inside it.

At 2,905 residents per square mile spread over 0.749 square miles, 18917 reads as a suburban area. It is a sparsely populated 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 track close to the national picture. The median of $75,000 puts 18917 near the middle of the pack, ahead of 58% 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 18917 costs well above the national median. A typical home is valued at $356,100 against a US median of $207,500, and median gross rent runs $1,342 a month. The split between owning and renting is fairly even at 59.9% 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 63.2% of housing units here. The median construction year is 1973, making the housing here from the later twentieth century.

The population skews broadly in line with the national age profile, with a median age of 42 against 42 nationally. The average household holds 2.19 people, and 51.8% are family households.

Getting to work takes 31.8 minutes on average one way. The dominant mode is drove alone at 83.9% of workers.

Beyond addressing mail, 18917 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, 18917 offers a compact profile of Dublin: 2,176 residents, a median household income of $75,000, 34.2% of adults holding a bachelor's degree or higher, and an unemployment rate of 3.0%. 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. 18917 may cover parts of several distinct areas, and a single neighbourhood in Dublin 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.
