Austin, TX

ZIP code 78701 is assigned to Austin, TX, and falls within Travis 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 11,114 people live inside it.

At 7,370 residents per square mile spread over 1.508 square miles, 78701 reads as a densely built-up 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 $154,867 places 78701 in the upper reaches of American postal codes, ahead of 97% 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 78701 costs far above the national median. A typical home is valued at $653,600 against a US median of $207,500, and median gross rent runs $2,732 a month. The split between owning and renting is fairly even at 49.0% owner-occupied, which tends to indicate a mix of housing types rather than one dominant form.

The building stock is dominated by larger apartment buildings of twenty units or more, which account for 82.6% of housing units here. The median construction year is 2006, making the housing here relatively modern.

The population skews broadly in line with the national age profile, with a median age of 41.5 against 42 nationally. Households average just 1.52 people, and 60.7% consist of one person living alone — a signature of areas with a lot of studio and one-bedroom stock.

Getting to work takes 24.8 minutes on average one way. The dominant mode is worked from home at 43.6% of workers, while 13.9% walk, 43.6% work from home. Commute patterns are one of the better proxies for how a place actually functions day to day.

Beyond addressing mail, 78701 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, 78701 offers a compact profile of Austin: 11,114 residents, a median household income of $154,867, 81.4% of adults holding a bachelor's degree or higher, and an unemployment rate of 1.5%. 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. 78701 may cover parts of several distinct areas, and a single neighbourhood in Austin 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.
