Johnstown, PA

ZIP code 15901 is assigned to Johnstown, PA, and falls within Cambria 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 3,466 people live inside it.

At 2,279 residents per square mile spread over 1.521 square miles, 15901 reads as a suburban 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 are well below the national median. At $27,946, 15901 ranks among the lower-income postal codes, ahead of 1% 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 15901 costs well below the national median. A typical home is valued at $19,200 against a US median of $207,500, and median gross rent runs $476 a month. The split between owning and renting is fairly even at 41.1% 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 52.5% of housing units here. The median construction year is 1947, making the housing here mid-century. The vacancy rate of 25.7% is high, which in many places reflects seasonal or second-home use rather than abandonment.

The population skews older than the national median, with a median age of 49 against 42 nationally. Households average just 1.77 people, and 65.7% consist of one person living alone — a signature of areas with a lot of studio and one-bedroom stock.

Getting to work takes 21.0 minutes on average one way. The dominant mode is drove alone at 74.3% of workers, while 11.2% walk. Commute patterns are one of the better proxies for how a place actually functions day to day.

Beyond addressing mail, 15901 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, 15901 offers a compact profile of Johnstown: 3,466 residents, a median household income of $27,946, 11.7% of adults holding a bachelor's degree or higher, and an unemployment rate of 11.1%. 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. 15901 may cover parts of several distinct areas, and a single neighbourhood in Johnstown 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.
